Abstract
The invention provides safe battery electrolyte. The safe battery electrolyte is prepared from the following raw materials in parts by weight: 50-70 parts of sulfuric acid, 20-30 parts of aluminum sulfate, 10-20 parts of anhydrous sodium sulfate, 10-20 parts of fumed silica, 3-8 parts of dodecyl acid diethanolamide, 1-5 parts of magnesium sulfate, 3-6 parts of powdered aluminum, 5-10 parts of inorganic additives and 1-3 parts of other auxiliaries. According to the safe battery electrolyte provided by the invention, the selected materials and lithium ion battery electrode materials have excellent compatibility, and also have the characteristics of relatively higher heat stability, relatively stronger oxidoreduction resistance, no aluminum foil corrosion and the like. If no non-water electrolysis functional additives are used, the electrolyte have more excellent high-temperature circulation and storage performance compared with the existing LiPF6 electrolyte prepared lithium ion battery.
Description
Technical field
The present invention relates to the electrolyte field in electrochemical techniques, be specifically related to the battery liquid of a kind of safety.
Background technology
Electrolyte be chemical cell, electrochemical capacitor etc. use have certain corrosive medium, the normal work for them provides ion.And ensure that the chemical reaction occurred in work is reversible.Liquid is relatively big with the contact area of medium, so helpful to promoting capacitance.Next to that use the electrochemical capacitor that electrolyte manufactures, can the high temperature of resistance to 260 °, thus can pass through wave-soldering (one important procedure of SMT paster installation), resistance to pressure is the strongest simultaneously.Additionally, use electrolyte to do the electrochemical capacitor of negative electrode, after medium is breakdown, as long as breakdown current does not continues, then electric capacity can spontaneous recovery.But existing electrolyte has the disadvantage in that the most readily volatilized, seepage, very big to life-span and stability influence, electrolyte is it is also possible to instant vaporization at high temperature under high pressure, and volume increase sets off an explosion, and some compositions has harm to environment, use dangerous；And resistance to low temperature is poor, battery under low temperature environment, is easily made to lose power supply capacity；Capacity stability is the highest, and after being used for multiple times, rated capacity decrement is relatively big, and battery availability factor is relatively low.
Detailed description of the invention
Not enough for prior art, the invention provides a kind of electrolyte using safety that can improve ion battery high temperature circulation, high/low temperature stable storage performance and capacity stability.
The present invention solves above-mentioned technical problem and uses this technical scheme to be: the battery liquid of a kind of safety, including the raw material of following parts by weight: 50 ~ 70 parts of sulphuric acid, 20 ~ 30 parts of aluminum sulfate, anhydrous sodium sulfate 10 ~ 20 parts, aerosil 10 ~ 20 parts, lauric acid diethyl amide 3 ~ 8 parts, 1 ~ 5 part of magnesium sulfate, Ethyl methyl carbonate 2 ~ 6 parts, aluminium powder 3 ~ 6 parts, inorganic additive 5 ~ 10 parts and other auxiliary agents 1 ~ 3 part.
