Abstract
The method for greatly increasing specific energy of combined battery features that low-rigidity, low-quality and light material such as thiner elastic rubber or plastics is used as shell of individual sub-battery and the sub-batteries are grouped in a large casing with better rigidity to bear higher pressure and load.
Description
The present invention relates to a kind of high voltage large capcity battery and production method thereof.Particularly a kind of method that can increase substantially the battery specific energy, and the novel battery group that adopts this method to make, this battery can be widely used in the various occasions that space travel, field work and electric automobile etc. need the high storage battery of specific energy.
The famous U.S. OVONIC laboratory of research high-energy battery of generally acknowledging in the world today, production can be used for battery (see figure 3) on the civilian use electric automobile, adopts formations that is together in series of 200 1.2V monomer Ni-MH batteries, it is 210Wh/L that its volume energy compares; Mass-energy is than being 70Wh/kg.This battery is considered to the highest electrokinetic cell of specific energy in the world at present.Because the monomer Ni-MH battery produces the gas hydrogen (H that responds in the charge/discharge process
2), its pressure reaches as high as tens kilograms/cm
2, therefore, each cell all must have intensity higher rigidity shell to bear this reaction gas pressure.The battery of this class is as fuel, zinc sky, aluminium sky, NI-G, lithium battery or the like.Export the occasion of big voltage or big electric current at needs, these cells need be together in series or parallel.At this moment, the outer rigid housing of each cell more volume that not only accounted for has also increased bigger weight; So just caused the unit volume or the Unit Weight of battery pack to export the little unfavorable result of energy down, influenced the extensive use of electrokinetic cell, particularly on the electric automobile practicability and civil nature that the saving power and preventing pollution that needs in 21st century dyes, produce very adverse influence.
The objective of the invention is to overcome the defective of prior art, a kind of method that can increase substantially the battery specific energy is provided.
This method is applicable to that all are in order to obtain the battery pack that high voltage carries out tandem compound and produces reacting gas, pressure.
Another object of the present invention is to overcome the shortcoming of existing battery, and a kind of very special battery pack of high-energy-density that has is provided.
Further purpose of the present invention is to provide a kind of and has simple in structurely, and low cost of manufacture does not have the battery pack of the high-energy-density of special special material.
Technical solution of the present invention is as follows: a kind of method that can increase substantially the storage battery specific energy comprises the steps:
A. battery lead plate (positive and negative pole plate or electrode) is packed into and battery lead plate have identical shaped cavity or the cover in, this cover coelosis is to be made by impervious elastic insulating material or other materials.
B. with contact conductor by the chamber or put corresponding hole or the conduit left and draw, and will seal up between lead-in wire and hole or the conduit; As adopt described below the third to implement can blow-by between alignment and hole or the conduit.
C. in chamber or cover, charge into the electrolyte of certain volume or other reactive material gas etc., then cover is sealed up, make it to be isolated from the outside;
D. will after above-mentioned a, b, c step, make a plurality of cells and pack in the rigid housing, and make and join each other between each cell unit and lean against on the inwall of stiff case;
E. with joining between the contact conductor both positive and negative polarity of above-mentioned each cell or being connected in parallel, draw, form battery pack through total contact conductor of outer rigid housing.
A kind of high-specific energy battery group that adopts said method to make, comprise a plurality of cells, the positive and negative electrode lead-out wire that forms on stiff case and the housing, described each cell by positive and negative pole plate, positive and negative electrode lead-out wire, the cavity that holds pole plate or elastic insulated cover and be contained in elastic insulated chamber or cover in electrolyte or other reactive material form; Described positive/negative plate or electrode are installed in chamber or the elastic insulated cover, in described chamber or put and have hole or conduit, positive and negative lead wires is drawn the outer or sealing of cover draws outside the cover, each cell phase ground connection is each other packed in the described outer rigid housing, and the positive and negative electrode lead-in wire of each cell links together in series or in parallel and joins with the contact conductor of shell.
The present invention compares with existing storage battery has the specific energy height, simple in structure, advantages such as the unrestricted and low cost of manufacture of materials used, and it can rationally use the interior space of battery case to greatest extent.Compare with the product of U.S. OVONIC company, under equal conditions, volume energy ratio can improve 35%, and the mass-energy ratio can improve 30%.Therefore, can be widely used in space travel, the field work, particularly it will provide good prerequisite to the development of electric automobile industry.

With reference to the accompanying drawings, the present invention is improved the method for battery specific energy and adopts the battery pack of this method manufacturing to be described further.
According to the mechanics basic principle, active force and reaction force equal and opposite in direction, direction are opposite, act on respectively on two objects.When the stiff case of losing each cell unit (this housing plays the gas pressure that the balance internal-response produces) and after changing elastic insulated cover into, when battery charging/discharging, the inner reaction gas pressure compressing resilient sleeve that produces expands, when the resilient sleeve after all spaces are inflated is full of, the power of the generation between each cell unit is cancelled out each other, and the expansion of cell unit that nestles up the outer rigid housing inwall is by the outer rigid housing balance.
Can also adopt second kind of scheme, soon stiff case is made the container of airproof and a charge valve is installed on housing, and at this moment, each the cell unit in the stiff case needn't closely be close together, and also can allow the gap between the inner walls.Before charge/discharge, the gas that charges into earlier certain pressure (equating with cell reaction gas maximum pressure) in airtight stiff case (can be air, hydrogen, nitrogen or carbon dioxide gas etc.), this gas pressure acts on enclosure interior everywhere equably, thus the bulbs of pressure that each cell is produced balance out.
Can also adopt the third scheme, the single battery that is combined in the stiff case not done independently sealing, and only stiff case is sealed.Work hard in glove with mutually by space in valve body, wireway and the rigid crust of an anti-liquid outflow, all single batteries that are combined in the rigid crust have a common balanced pressure environment with this, can be provided with tongue and groove in order to make the rigid crust physical efficiency bear bigger rock deformation pressure on housing.
