BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a zeolite type battery and a method of manufacturing the same. Specifically, nickel oxide, which is an oxide, is made of nickel oxide nano by crushing with oxygen gas, and then replaced with hydrogen gas to be porous. Nickel oxide powder was prepared, rolled to a thickness of 0.02 mm, and then annealed to prepare a cathode electrode material, and copper oxide nano made by crushing copper oxide with oxygen gas. Substituted by hydrogen gas to make copper oxide powder (roller oxide powder) and then rolled to a thickness of 0.02mm and annealing to prepare a cathode electrode material. Electrolyte (KOH) is prepared by mixing an electrolyte material with a low unit critical Fermi constant in a stirring furnace for a long time to prepare an electrolyte (KOH), and the pores are fine and filled with a three-dimensional honeycomb electrode. The present invention relates to a zeolite type battery and a method of manufacturing the same, which have a function of dissipating and dissipating a large amount of ion particles quickly due to a low resistance value during discharge.

In general, a storage battery is mounted on a vehicle regardless of a gasoline vehicle or a diesel vehicle, and is used as a power source for starting, ignition, lighting, and other electrical equipment of an engine.

Car batteries, which have been widely used, are also called lead acid batteries because the working substance is lead, and was invented by French physicist Gaston Plante in 1859 and was used for the first time in the 1920s.

Such a battery is composed of a positive electrode and a negative electrode made of different metals as electrodes, and these and an electrolyte are connected, and when the positive electrode is connected with a conductor, the chemical energy of the working material and the electrolyte of each electrode can be made into electrical energy.

On the contrary, the addition of electrical energy allows it to revert back to the original agent with chemical energy.

The reversible action is called a battery (secondary cell), and the irreversible one is called a primary cell.

The difference between batteries and primary cells is that they can generate and supplement electrical energy as needed, and are generally classified into lead-acid and alkaline batteries.

Lead-acid storage batteries are widely used in vehicles as batteries using dilute sulfuric acid (2H2SO2) as an electrolyte, lead peroxide (PbO2) as the positive electrode, and pure lead (Pb) as the positive electrode.

Alkali storage battery is a battery that uses potassium hydroxide (KOH) solution as electrolyte, 2 nickel hydroxide (2Ni (OH) 3) for positive electrode plate, and cadmium (Cd) for positive electrode plate. It is easy but the price is high and there is a disadvantage that can not meet the demand of nickel.

And since 1991, when the charging (or secondary) lithium-ion battery system was introduced and industrialized, it has received considerable attention not only in the battery field but also in the electric and automotive industry. In lithium-ion batteries, carbon or graphite is used as the cathode, the lithiated transition metal intercalation compound is used as the anode, and LiPF 6 is used as the electrolyte in the carbonate-based organic solvent.

For example, the overall cell scheme of an oxide comprising a reaction at an electrode and a lithium insertion compound is as follows:

charge

Anode LiMO2 ⇔ Li1-XMO2 + xLi + + xe-

Discharge

charge

Cathode C + xLi + + xe- ⇔ LiXC

Discharge

charge

Total LiMO2 + C ⇔ LiXC + Li1-XMO2 <10>

Discharge

LiMO2 here represents a lithium metal oxide insertion compound.

Recent cathode

Heavy carbon and graphite are used as active negative electrode materials in commercial lithium-ion batteries. Polyvinylidene fluoride (PVDF) is used as a binder to improve the mechanical properties of the electrode. Copper is widely used as the substrate for cathodes. Heavy carbon and graphite materials are mixed in PVDF and an organic solvent and the mixture is coated on a copper substrate to prepare the cathode.

Circulation life and self discharge problem

During the charge-discharge process, the insertion and removal of lithium-ions results in significant expansion and contraction of the negative electrode, resulting in loose mechanical properties resulting in increased impedance of the electrode. This increase in negative impedance results in a decrease in the capacity of the lithium-ion battery in circulation. Current lithium-ion batteries in the art provide approximately 500 cycles with 100% discharge and 80% capacity retention. Many applications (eg, aerospace and transportation) require high cycle life.

Another disadvantage of lithium-ion batteries in the art is the relatively high self-discharge. Current lithium-ion batteries lose capacity between 7% and 12% per month at ambient temperature. This loss is higher at higher temperatures.

Overcharge / Overdischarge Problems

Current lithium-ion batteries in the art require overcharge / over-discharge protection circuits and / or devices so that the cells can be charged and discharged within a range of potentials. Overdischarge causes decomposition of the copper used as the substrate of the carbon negative electrode, which degrades battery performance.

During overcharge, many lithium-ions migrate to the carbon cathode and the cathode does not have enough space to accommodate them, causing metallic lithium precipitation on the cathode, heating the composition, and finally dissipating heat in the cell. .

Overcharge / over-discharge protection circuits and / or devices also increase the weight and cost of lithium-ion batteries. Reliable and inexpensive overcharge / over-discharge protection for multi-cell lithium-ion batteries is a major obstacle to the commercialization of electric transport devices and other high potential applications.

Lithium ion cells are generally used as host cathode and anode materials for reversible insertion of guest ions (eg, lithium ions or other alkaline metal ions) when providing an electrochemical reaction to generate a current. Different intercalating compounds, ie intercalating materials, are used.

During discharge of a lithium ion cell, lithium ions are extracted from the lithium ion containing anode material and ionically transferred into the cathode through the electrolyte / seperator, with the generation of an external current. A reverse process, along with the reversal of ion flow, occurs during charging of the cell.

Lithium ion cells may be conventional liquid electrolyte cells, which generally have a non-aqueous organic nature, ie, have a free liquid, or have a "solid state" with a polymeric porous substrate to which the electrolyte is immobilized. May be a cell of ".

The polymer matrix consists of a porous partition between the anode and the cathode so that the necessary ions can be transferred between the anode and the cathode.

In solid state rechargeable or "secondary" cell systems, lithium (or other electrochemically active metal) is contained in a non-aqueous electrolyte, whether free or fixed in a polymer matrix. It is transferred back and forth between the cathode and the anode in the form of dissolved ions.

Due to the electrolyte fixation in the polymer cell, the necessary function of the cell structure, the stability and the flexibility of the dimensions, the rate of ion transfer is reduced.

This results in lowering both the cell discharge capacity and the regeneration efficiency, especially under the use conditions after the high temperature storage condition.

Although various methods have been used, particularly in various cell components, and especially in the types of electron and ion transfer enhancing additives and stabilizers included in the anode and the electrolyte, these methods have only a slight effect. Aside from ion conductivity and electronic conductivity, other variables are included in the degradation of cell performance that conventional approaches have failed to efficiently address.

Thus, Korean Patent No. 10-0830247 (Lithium-ion Electrochemical Cell and Battery) dated May 09, 2008 was proposed.

It comprises an aprotic non-aqueous electrolyte body, first and second electrodes in contact with the electrolyte, the first electrode comprising a lithium intercalating mixture, and the second electrode having a predetermined discharge rate and charge rate. A substrate designed to provide overcharge and overdischarge capacity to a battery having a substrate, the substrate comprising a carbon-carbon composite material,

A plurality of electrochemical cells, each cell comprising a non-aqueous secondary battery, each cell having a predetermined discharge rate, and each cell having a negative electrode of a carbon based material providing a battery having an overdischarge capacity; Each cell consisted of a negative electrode having a substrate comprising a carbon-based material.

In addition, in the structure of the conventional lithium-ion battery,

Cathode positive and negative electrode plates (cathode electrode materials) were fabricated in a concave-convex shape or a patterned shape to expand the unit area on a 0.01 to 0.02mm copper foil plate for excellent workability.The main materials are LiCoO3, LiNiO2, and LiMnO4. Recently, China's BYD and SS USA's EnerDel have been known to use LiFe2PO4 material, which has been booming in China because of its easy alloy and low price. I use material.

Cathode charging and discharging electrode plates, which are anodes (cathode electrode materials), are also manufactured in a concave-convex shape or a patterned shape in order to expand the unit area on a 0.01 to 0.02mm copper foil sheet for excellent workability. , China and the United States adhere to the Ni / MH specification.

Potassium hydroxide (KOH) is the easiest material to produce an electrolyte of oxide metal that chemically reacts a cathode and an anode to produce a positive electrode and a negative electrode.

Polyolefin (Polyolefin) is a polyamide-based separator used in combination with polypropylene.

However, according to the conventional lithium-ion electrochemical cell and the lithium-ion battery including the battery, the number of pores is limited to the two-dimensional electrode plate and the manufacturing method thereof, which are processed in the form of unevenness or etching on the cathode and the anode. Potassium hydroxide (KOH), which is an electrolyte of an oxide metal that produces a positive electrode and a negative electrode by chemically reacting a cathode and an anode, as well as maximizing charging ability, has many problems in terms of function.

Accordingly, the present invention is to solve the conventional problems as described above, to form a nickel oxide nano nanoparticles (nickel oxide nano) while crushing the nickel oxide (nickel-oxide) oxide with oxygen gas and replaced by hydrogen gas porous After making nickel oxide powder, it is rolled to a thickness of 0.02mm and annealed to produce a positive electrode material, and the pores are fine in a three-dimensional Bee-Hive type in which the anode electrode and the cathode electrode are three-dimensional. It is an object of the present invention to provide a zeolite-type battery and a method of manufacturing the same, which have a function of dissipating and dissipating a large amount of ion particles quickly due to a low resistance value during charging and discharging.

The copper oxide nano made by crushing copper oxide with oxygen gas is made, and then substituted with hydrogen gas to make copper oxide powder, which is rolled to a thickness of 0.02mm and annealed to form a cathode electrode material. It is another object to make the material.

In addition, another object of the present invention is to prepare an electrolyte (KOH) by mixing an electrolyte material synthesized with a hydroxide having a low unit critical Fermi constant in a stirring furnace for a long time.

The zeolite battery of the present invention and its manufacturing method for achieving the above object,

In the process of producing a porous nickel oxide powder by replacing with hydrogen gas in a rotary kiln at high temperature,

A process of preparing an electrolyte (KOH) by mixing a hydroxide and a metal synthesized with a low unit critical Fermi constant in a stirring furnace for a long time to produce an anode, a cathode, and an electrolyte (KOH) to ionize the carbon fine pores It collects ion particles released by a lithium gas, and the anode and cathode electrodes, which are the combined structure of nano metal zeolite, are three-dimensional honeycomb type, and the pore size is fine and the resistance value is small during charging and discharging. In addition to having the function of dislocation and dissipation of particles, the unit microparticles to be exchanged are nano-type and zeolite-type having many pores, and thus can move rapidly and a large amount of ionic particles effectively in a low resistance state. Zeolite type with many pores to induce electrons well Characterized in that configured.

According to the zeolite type battery according to the present invention and a method for manufacturing the same, the average capacity of the current battery when the existing positive electrode and the negative electrode are applied to the zeolite type positive electrode, the zeolite type negative electrode and the electrolyte (KOH) as the metal zeolite It is expected that the capacity of 20 to 40V and 140 to 200Ah is greatly improved from 3 to 4V and 20Ah, and it is possible to improve the Fermi dislocation particles and to suppress the potential electron absorption disturbance element by absorbing oxygen and hydrogen in a large amount, and to suppress the generation of moisture. It works.

In addition, since the metal zeolite has a pore amount of 2,000 to 20,000 times compared to the method of forming pores by two-dimensional unevenness or etching on a conventional negative electrode material thin plate, a large amount of charged ion particles are collected in the negative electrode material. It will have the ability to charge.

When the potential of the electron particles at the cathode of the metal zeolite and the anode and anode of the anode is lowered, a larger amount of hydrogen is generated as the Fermi level decreases, but the metal zeolite easily releases hydrogen due to the increase of the particle interface generated during charging. Absorption increases the filling of the ion particles.

The anode electrode plate is mainly made of nickel oxide, and it is easy to manufacture various kinds of electrode plates such as Ni / MN, LaNi5, MnNi5, 2LiMO2, LiCo2, LiNiO2, and the cathode electrode plate may be manufactured using mainly copper oxide. When oxygen is generated in electrolyte, the surface area of the interface is suppressed to prevent water generation, and thus, it charges and discharges quickly and controls many ion particles by controlling the electronic unit Fermi value.

When the hydroxide, which is a conventional electrolyte (KOH), is composed of nano zeolite, hydrogen and oxygen of the cathode, anode react to generate water. By trapping and releasing the generated gas, it is possible to suppress the increase in pressure, increase the ion particle potential, and to realize a secondary battery having high efficiency.
