The invention can eject the residue gas in the cell after the pre-charge in order to avoid the safety hidden trouble.
Description
[technical field]
The present invention relates to the lithium ion battery field, be specifically related to the manufacture method and the battery of lithium ion battery.
[technical background]
In recent years, the function of computer, communication electronic product and consumption electronic products is more and more stronger, and its overall dimension requirement is more and more littler, quality is more and more lighter, so high power capacity, undersized battery product receive an acclaim.Lithium ion battery particularly, characteristics such as capacity is big, energy density is high, voltage height that it has constantly rise in the occupation rate of market of products such as mobile phone, notebook computer, digital camera.
Lithium ion battery is with lithium and cobalt oxides (LiCoO
2), lithium nickel oxide (LiNiO
2) or lithium manganese oxide (LiMn
2O
4) wait and be positive electrode active materials, be negative active core-shell material with lithium metal, lithium alloy or material with carbon element.Its electrolyte can use liquid state organic electrolyte or solid gel electrolyte, and the latter is called lithium polymer battery (Lithium Polymer Battery) again, and commonly used is liquid electrolyte at present.The liquid electrolyte that lithium ion battery uses is organic non-aqueous solution, as ethylene carbonate (EthyleneCarbonate, EC), diethyl carbonate (Diethyl Carbonate, mixture DEC) is a solvent, with lithium salts (as LiPF
6) be solute, and add a small amount of additive and form.
The lithium ion battery production technology generally comprises following steps: the assembling of both positive and negative polarity batching → both positive and negative polarity coating → both positive and negative polarity film-making → electric core → → fluid injection and preliminary filling → seal.Because battery is in charge and discharge process, the polarity active material of battery can produce in some gases, particularly preliminary filling process with the electrolyte reaction, and the gas of generation is more, as untimely discharge, will bring potential safety hazard to battery.
[summary of the invention]
At the deficiency of above present lithium ion battery production technology, the object of the present invention is to provide a kind of inside battery gas behind the preliminary filling can the discharge, avoid bringing the lithium ion battery manufacture method of potential safety hazard to battery.
Another object of the present invention is to provide a kind of lithium ion battery made from said method.
For achieving the above object, the present invention is by the following technical solutions:
A kind of lithium ion battery manufacture method, step such as it comprises batching, coating, film-making, assembling, fluid injection, preliminary filling, seal is characterized in that: also comprise the step that the battery behind the preliminary filling is toasted.
The further part of this technical scheme is: the battery behind the preliminary filling is positioned in the baking oven toasts, and use the dry gas protection.
Above-mentioned dry gas comprises dry air, nitrogen, inert gas etc., preferred nitrogen.
The temperature of toasting in the said method is 40-80 ℃, preferred 55-65 ℃, and most preferably 60 ℃.
The time of toasting in the said method is 4-8 hour, preferred 5-7 hour, and most preferably 6 hours.
The present invention also provides a kind of lithium ion battery made from said method.
Adopting said method to compare the beneficial effect that is produced with prior art is: by increasing the step of baking, can more completely the gas that remains in inside battery behind the preliminary filling be discharged, thereby avoid because the potential safety hazard that residual gas brings to battery.
[embodiment]
The invention provides a kind of lithium ion battery manufacture method, step such as it comprises batching, coating, film-making, assembling, fluid injection, preliminary filling, seal is characterized in that: also comprise the step that the battery behind the preliminary filling is toasted.By the battery behind the preliminary filling is toasted, can more completely the gas that remains in inside battery behind the preliminary filling be discharged, thereby avoid because the potential safety hazard that residual gas brings to battery.The temperature why the present invention selects to toast is 40-80 ℃, is because if the temperature of baking is when being lower than 40 ℃, and the efficient of baking is not high can not discharge residual gas more completely, and the time of baking is longer, has prolonged the battery manufacturing cycle; When being higher than 80 ℃, return electrolyte volatilization on the one hand with liquid state, bring adverse effect to battery performance, temperature is too high on the other hand, can destroy the battery positive/negative plate barrier film, and barrier film is a macromolecular material, and the contraction situation appears in the too high meeting of temperature.The time why selection is toasted is 4-8 hour, is because the time too short (＜4 hours), baking not exclusively can not drain residual gas; Stoving time long (＞8 hours) has prolonged production cycle of battery.Be because avoided moisture to enter battery with dry gas protection when battery toasts in baking oven, bring adverse effect to battery, preferred nitrogen be because, the nitrogen price is compared with inert gas and is not too expensive, to compare composition single with air.To further specify realization of the present invention with concrete example below.
