Abstract
A method for injecting electrolyte into lithium battery includes laying stainless steel support with liquid injection holes being arranged regularly towards to injection product into soaking box of injection liquid, covering and sealing said box then vacuuming said box to form negative pressure at internal of said battery, injecting electrolyte into said box and automatically sucking in electrolyte by said battery in said box under action of negative pressure.
Description
Technical field
The present invention relates to a kind of injection process technical field, relate in particular to the electrolyte method for implanting technical field of battery, electric capacity.
Background technology
Traditional battery, the fluid injection of electric capacity, be to adopt the rotating disc type fluid injection, need to be about to the battery of fluid injection or the liquid injection hole of electric capacity upwards to arrange, on rotating disc type fluid injection machine, filling head inserts and treats in the liquid injection hole of intercell, pulls out a filling head before the fluid injection earlier, be placed in the beaker under it, extract the air in all the other battery liquid-filling needle tubings, have electrolyte to flow out in the pipe behind the no bubble on the filling head in beaker, can transfer reservoir quantity to carry out fluid injection.Battery after each fluid injection all needs to weigh, and confirms whether battery fills complete.Then need carry out fluid injection more than the secondary to the battery of high power capacity, just can reach designing requirement.If meet the battery of different models, then will manually adjust to the filling head height.Homogeneity of product with the fluid injection of said method institute is poor, and is in batches little, troublesome poeration, and production efficiency is low, and rotating a circle usually at most can only fluid injection more than 10, the equipment cost height, maintenance, maintenance and human input are all more.
Summary of the invention
The purpose of this invention is to provide a kind of easy to operate, effective, big in batches liquid filling method for lithium battery.
Technical scheme of the present invention be achieved in that with neat discharging have liquid injection hole downwards and half-finished support integral body for the treatment of fluid injection put into the sealing of fluid injection soaking box and build, and soaking box vacuumized, after treating the inner formation of semi-finished product negative pressure, inject electrolyte in case, semi-finished product then suck electrolyte automatically in the case under suction function.
The present invention is when fluid injection, and the semi-finished product of disposable fluid injection can reach 200～500, and does not have repetition fluid injection phenomenon, has improved labor productivity greatly; The fluid injection high conformity has guaranteed the quality of fluid injection, and has realized energy-saving and cost-reducing.Process of the present invention is rationally advanced, and is effective.
Embodiment
Method of the present invention is to have liquid injection hole to treat that downwards the half-finished stainless steel stent integral body of fluid injection puts into fluid injection soaking box sealing and build neat discharging, and the fluid injection soaking box vacuumized, after treating the inner formation of semi-finished product negative pressure, inject electrolyte in case, semi-finished product then suck electrolyte automatically in the case under suction function.Vacuum degree and reservoir quantity according to treating the half-finished quantity of fluid injection, preestablish before fluid injection.With 413450A type battery is example, adjusts control air pressure before the fluid injection, sets vacuum degree to be-0.1Mpa, and reservoir quantity is 2.7g/.1,350 semi-finished product liquid injection holes will treating fluid injection neatly are emitted on downwards on the stainless steel stent, again stainless steel stent integral body are put into the fluid injection soaking box, build seal cover; 2, the fluid injection soaking box is vacuumized; 3, when vacuum degree in the case reach-during 0.1Mpa, reservoir channel is opened automatically, and by predefined 2.7g/ reservoir quantity fluid injection in case only.At this moment, the electrolyte that will inject automatically in the case under suction function of the semi-finished product in the case is drawn onto in the semi-finished product body.Every case fluid injection time generally only needed to finish in 3-4 minute.
