Abstract
The present invention relates to a magnesium manganese laminated battery. The anode material of said laminated battery is a continuously-cast or continuously cast-rolled magnesium alloy thin sheet which is a alloy in which the magnesium is used as base body and several elements are added, and its anode and cathode combined conductive layer is multifunctional, and its battery diaphragm is made up by adopting natural fibre paper impregnated with polysulfone solution.
Description
Technical field:
The present invention relates to a kind of chemical power source, especially belong to magnesium manganese laminated cell group.
Technical background
The characteristics of magnesium manganese laminated cell group are high voltage, high power, high power capacity, anti-storage, low temperature performance excellence, environmental protection (no mercury lead-free and cadmium-free).In addition, this battery raw material aboundresources, production technology are simple, and production cost is low.Communication, electrical equipment, military affairs etc. need the advanced more laminated cell group of performance.Magnesium manganese laminated cell group does not obtain commercialization and promotes, and except that the factor of technical elements, magnesium alloy costs an arm and a leg, and lacks the effective ways that reduce cost.
(GJB885-90 GJB319A-97) can find, the specific energy of existing magnesium manganese laminated cell group is not high by military magnesium cell standard.Press the criterion of the specific energy of battery preferably, the actual specific energy can reach the 1/3-1/5 of theoretical value, the theoretical specific energy of magnesium manganese cell is 726 watt-hour/kilograms, and the 54 watt-hour/kilograms of only having an appointment during in fact existing magnesium manganese laminated cell group heavy-current discharge, only reach 1/13.5 of theoretical value, obviously do not reach due level.Have many from theory analysis reason wherein, the raising that the processing technology that comprises magnesium alloy anode haves much room for improvement, the anode alloy tissue is unfavorable for current efficiency, bipolarity conducting film function defectiveness, the temperature during because of the big work of the internal resistance of cell raise and cause battery electrolyte volatilization loss etc.
Magnesium alloy belongs to the close-packed hexagonal crystal structure, have only a slip plane in room temperature, so the plastic deformation ability of magnesium alloy is than aluminium alloy difference.Magnesium manganese laminated cell group magnesium alloy sheet uses extruding or rolling mode, production process complexity, production cost height now.
The tissue of extruding or rolling magnesium alloy plate is not suitable for the requirement of magnesium manganese laminated cell anode, and stress corrosion and breakaway corrosion take place the both easily, reduces the utilance of magnesium.
Magnesium anode one side has one deck bipolarity conducting film to contact with electric core negative electrode in magnesium manganese laminated cell, its effect is that negative and positive the two poles of the earth are connected with minimum resistance, the bipolarity conducting film must possess the function of anti-electrolyte permeability, anti-magnesium alloy corrosion simultaneously, make the magnesium alloy electrode be in stable state, otherwise electrolyte infiltrates and causes the magnesium corrosion, the utilance that had both caused magnesium reduces, and also causes the internal resistance of cell to increase, and voltage drop is accelerated.
The barrier film of magnesium manganese laminated cell is different with other battery request to be that its resistance should be littler, owing to above-mentioned identical, when the internal resistance of barrier film is big, also must cause the electric core dehydration of battery serious, voltage drop is accelerated during work.
Summary of the invention:
The present invention adopts the casting of rapid solidification or rolling casting technology can realize the requirement of electrochemistry anode to material structure better, continuous casting or continuous casting and rolling can be produced the magnesium alloy plate of the thickness below 1 millimeter of magnesium manganese laminated cell needs economically, and laminose tissue characteristic is from the ingrown column crystal of superficial layer, meets the requirements especially.
The standard electrode potential of metal can be used as the foundation of weighing its resistance to corrosion, and the standard electrode potential of magnesium is-2.37 volts, is very low in metal, therefore very easily corrosion.Must possess low resistance, flawless, bottom as the bipolarity conductive layer of magnesium alloy anode in battery has good wetability and high adhesion force, anti-overvoltage, resisting high-concentration salt solution, inhibition, anti-infiltration, strong cohesive force, cost lower to magnesium alloy.But magnesium manganese laminated cell group waits deeply the research of magnesium alloy anode conductive at present.The present invention studies the formation of conductive for this reason, from film forming matter, conductive filler, diluent, curing agent, all too many levels control of antirust chromic salts filler, meets multi-functional requirement to reach.
Barrier film adopts natural fiber paper, compares with other existing diaphragm material.After adopting natural fiber paper, not only performance improves but also production cost reduces.But common wood fibre paper can not stop the diffusion of manganese dioxide particle fully, may cause battery short circuit, do not increasing under the resistance prerequisite of barrier film for this reason, take to prevent the measure of manganese dioxide particle via the diffusion of fibre gap anode, the pellicle that does not promptly allow to see through manganese dioxide particle with seeing through electrolyte ion is handled.The present invention adopts the natural fiber matter paper of polysulfone semipermeable membranes processing.
Magnesium manganese laminated cell group adopts version, technical parameter and the using method of common zinc-manganese laminated cell group in addition, so that the interchangeability of different battery when using.And with process route, the device fabrication magnesium manganese laminated cell group of common zinc-manganese laminated cell group, so that different battery production can be compatible.
Embodiment
Magnesium manganese laminated cell group adopts version, technical parameter, process route, the equipment identical with zinc-manganese laminated cell group to produce.
Magnesium alloy anode thin slice composition is to be matrix with magnesium, and contain the aluminium of 5-8%, the zinc of 0.5-2.5%, the manganese of 0.1-0.5%, the trace additives of 0.1-1% (trace additives can be alkali metal, alkaline-earth metal, rare earth metal etc.), optimal components is: 6% aluminium, 1.5% zinc, 0.35% manganese, 0.25% alkaline-earth metal, all the other are magnesium.
The anode thin slice is to adopt continuous casting or continuous casting rolling technology from the one-time formed magnesium alloy thin slice of liquid magnesium alloy, and the thickness of anode magnesium alloy thin slice is chosen according to the model of battery.
Anode conductive layer contains 60～80% graphite, 10～23% bituminous epoxy, the lanolin of 5-15%, the chromate of 1-2%, 4%-10% polytetrafluoroethylene.
The natural fiber matter paper that barrier film adopts polysulfone semipermeable membranes to handle, about 0.1 millimeter of dried paper thickness, polysulfones are glue connection and micropore between the paper fiber, micropore accounts for 40%, 2 microns of micro-pore diameters.
It is same as the prior art that present embodiment is not stated part.
The present invention has carried out the experiment of assembled battery group, and is every functional, and index is apparently higher than the common zinc-manganese laminated cell group of same model and the military standard of magnesium manganese laminated cell group, and better low temperature performance and high temperature resistant storge quality are arranged.Experimental result shows that it is simple that the present invention has manufacture method, and is cheap, high comprehensive performance, and the non-environmental-pollution problem during use and same model zinc-manganese laminated cell group compatibility, can be exchanged.
