Description

Battery with a battery cell

Technical Field

This application claims prior benefit from U.S. patent application Ser. No. 12/344,211, filed 24, 2008, and Taiwan patent application Ser. No. 97118207, filed 16, 5, 2008. The entire contents of the above two patent documents are incorporated herein by reference.

The present invention relates to a battery and a method for manufacturing the same, and more particularly, to a battery using chlorophyll to generate electric energy and a method for manufacturing the same.

Background

In recent years, portable electronic devices such as mobile phones, portable video cameras, notebook computers, digital cameras, PDAs, CD players, and the like have been developed, and in order to achieve a reduction in size and weight, they have also been attracting attention as portable power sources, i.e., batteries. The battery types include dry batteries, nickel-metal hydride batteries, lithium batteries, fuel cells, and the like. A general battery will be briefly described below.

The dry batteries used in daily life are mostly zinc-manganese batteries, also called carbon-zinc batteries. The housing of a carbon zinc battery is typically constructed of zinc, which can serve as both the container and the negative electrode of the battery. Carbon zinc cells were developed from liquid lecranch cell. The traditional or general type carbon zinc battery takes ammonium chloride as electrolyte; the super or high-energy carbon zinc battery is usually a carbon zinc battery using zinc chloride as electrolyte, and is an improved version of a generally cheap battery. The positive electrode of the carbon-zinc battery is mainly composed of powdery manganese dioxide and carbon. The electrolyte is a paste solution formed by dissolving zinc chloride and ammonium chloride in water. Carbon zinc cells are the cheapest primary cell and are therefore the primary choice for many manufacturers, who often distribute the cells in their equipment. The zinc-carbon battery can be used for devices with low power, such as remote controllers, flashlights, toys or transistor radios and the like.

However, when the carbon zinc battery is used for a certain period of time, the zinc can becomes thinner gradually as the metallic zinc is oxidized into zinc ions. Thus, the zinc chloride solution can often leak out of the cell. The zinc chloride that leaks out tends to make the surface of the battery sticky. Some older batteries have no leakage protection. The service life of the zinc-carbon battery is short, and the storage life is generally one and a half years. In addition, even if the battery is not used, ammonium chloride in the battery has weak acidity and can react with zinc, and the zinc can is gradually thinned.

Lithium batteries commonly mentioned in the 3C industry are actually lithium cobalt batteries, and the broad sense of rechargeable lithium batteries is that a graphite cathode, a cathode using cobalt, manganese or iron phosphate, and a lithium batteryElectrolyte for transporting lithium ions. While the primary lithium ion battery may have lithium metal or lithium intercalation materials as the negative electrode. The lithium battery industry has been mainly focused on the 3C industry for more than 20 years, and is rarely applied to the market with larger energy storage and power batteries (instantly needing larger current) in market economic scale, and the market covers the fields of pure electric vehicles, oil-electricity hybrid vehicles, medium and large UPS, solar energy, large energy storage batteries, electric hand tools, electric motorcycles, electric bicycles, aerospace equipment, batteries for airplanes and the like. The main reason for this is the lithium cobalt positive electrode material (LiCoO) used in lithium batteries in the past ₂ The most common lithium battery) can not be applied to special environments which need large current, high voltage and high torque and have the conditions of puncture resistance, impact resistance, high temperature, low temperature and the like, and more importantly, the most important lithium battery can not meet the absolute requirements of people on safety and suffers from scaling.

Meanwhile, the lithium cobalt battery cannot achieve the purposes of rapid charging and complete avoidance of secondary pollution, and a protection circuit must be designed to prevent overcharge or overdischarge, which would cause explosion and even cause huge capital recovery for NB owners of the global brand due to the explosion of Sony batteries.

In addition, the price of cobalt is higher and higher, and the biggest producing country of cobalt element in the world has congo and many war breaks down, so that the price of the cobalt element is continuously increased. The price of the powder of the lithium cobalt battery is continuously increased, and the price is increased from original 40 dollars per kilogram to 60-70 dollars. The lithium iron phosphate powder is good or bad according to the quality, and the selling price of each kilogram is between 30 and 60 dollars.

The design of nickel-metal hydride batteries stems from nickel-cadmium batteries. In 1982, the U.S. OVONIC company requested a patent for hydrogen storage alloy to be used for electrode manufacturing, so that the material is regarded as important, and subsequently, in 1985, dutch Philips company breaks through the problem of capacity attenuation of the hydrogen storage alloy in the charging and discharging processes, so that the nickel-metal hydride battery is distinguished. At present, more than 8 manufacturers of nickel-metal hydride batteries exist in Japan, and the nickel-metal hydride batteries also exist in Germany, america, hong Kong and Taiwan, so that the market reaction is good. Also, the pollution caused by the nickel-metal hydride battery is much smaller than that of the nickel-cadmium battery containing cadmium, so that the nickel-cadmium battery has been gradually replaced by the nickel-metal hydride battery.

Fuel cells (Fuel cells) are devices that use Fuel to perform chemical reactions to generate electricity, and were first put into practical use by Grove in the uk in 1839. Most commonly, proton exchange membrane fuel cells using hydrogen and oxygen as fuel are suitable in fuel price, have no chemical risk to human bodies and no harm to environment, generate pure water and heat after power generation, are applied to the U.S. military in the 1960 s, and are applied to U.S. Gemini constellation plan Gemini constellation No. 5 spacecraft in the 1965 s. Some notebook computers are now also beginning to use fuel cells. However, the generated electric quantity is too small to provide a large amount of electric energy instantly, and the electric energy can only be used for smooth power supply. The fuel cell is a power mechanism in which a cell body and a fuel tank are combined. The fuel has very high selectivity, including pure hydrogen, methanol, ethanol, natural gas and even the most widely used gasoline at present, and can be used as the fuel of the fuel cell.

In the production of the novel carbon zinc battery, alkaline battery and secondary battery, which are emphasized to be environment-friendly, a small amount of mercury or other heavy metals such as cobalt is used, and polluting substances are used in raw materials and production, so that the novel carbon zinc battery, alkaline battery and secondary battery are harmful to the environment and human body.

Lithium batteries, which are widely used at present, belong to unstable electrochemical devices, and can cause explosion if the lithium batteries are improperly packaged and operated under low load. Multiple complex protection mechanisms are therefore required, such as including protection circuits for preventing overcharge, overdischarge, overload, overheating, etc., vent holes, isolation membranes, etc.; the vent hole is used for avoiding overlarge internal pressure of the battery; the separator has high puncture resistance to prevent internal short circuits, and also melts at an excessive temperature inside the battery, preventing lithium ions from passing therethrough, retarding the battery reaction, and increasing the internal resistance (to 2 k.OMEGA.).

Positive electrode for lithium battery (e.g., li) _1-x CoO ₂ ) Negative electrode (Li) _x C) The main raw material lithium ore is less and less, so that the price of the lithium ore rapidly rises.

Lithium batteries begin to rapidly degrade in both performance and life in the presence of slightly elevated temperatures outdoors or in an environment.

The nickel-cadmium battery or nickel-hydrogen battery has memory effect, and is easy to cause reduction of available capacity due to poor charging and discharging.
