Abstract
A method for rapid penetration of a lithium ion battery electrolyte into a winding core is as follows: after electrolyte injection of a lithium ion battery, performing constant voltage constant current charging to 3500mV with the charging current of 0.05 C and the charging time of 40-60 min; putting the lithium ion battery aside for 4-10 min; performing constant current discharging to 3000mV with the discharging current of 0.05 C and the discharging time of 40-60 min; again putting the lithium ion battery aside for 4-10 min; and circulating from the first step to the fourth step for 5 times. The advantages of the method are that: the lithium-ion battery electrolyte can rapidly penetrate into the winding core, the production cycle is shortened, the whole production process of the lithium ion battery is more smoothly, and the production efficiency is increased.
Description
Technical field
The present invention relates to a kind of method of electrolyte permeability volume core, relate in particular to a kind of method of lithium-ion battery electrolytes rapid osmotic volume core.
Background technology
At present, lithium ion battery has advantages of high voltage, height ratio capacity and high-specific-power, important new forms of energy have been become, be widely used on mobile phone, notebook computer, digital camera, video camera, portable DVD player, panel computer and various power tool, existing lithium ion battery is used after fluid injection the i.e. 1440 ~ 2880min of standing 24 ~ 48h() thus electrolyte slowly permeate volume core re-use can charging/discharging apparatus on chemical synthesis technology, but its shortcoming is when to be lithium ion battery standing, temperature is normal temperature, time of repose is long, efficiency is low, also needs to arrange standing place.
Summary of the invention
The object of the present invention is to provide a kind of method of lithium-ion battery electrolytes infiltration volume core, the direct use of the method can discharge and recharge the little electric current of lithium ion battery to make electrolyte rapid osmotic volume core direct chemical synthesis technology again by charging/discharging apparatus, can reduce the electrolyte permeability time, raise the efficiency, shorten the production cycle.
The present invention is achieved like this, and it is characterized in that method step is:
(1) constant-current constant-voltage charging is to 3500mV, charging current 0.05C, charging interval 40-60min;
(2) lithium ion battery is shelved 4-10min;
(3) constant-current discharge is to 3000mV, discharging current 0.05C, discharge time 40-60min;
(4) lithium ion battery is shelved 4-10min again;
(5) the circulation first step to the four step is 5 times;
(6) arrange and normally change into work step.
Of the present invention by after lithium ion battery homepage, be arranged on can charging/discharging apparatus on, arrange and above-mentionedly start charging/discharging apparatus after discharging and recharging step.
Battery-heating so that electrolyte rapid osmotic in charge and discharge process of the present invention.
The electrolyte permeability process required time 440-700min altogether that discharges and recharges of the present invention.
Advantage of the present invention is: make lithium ion battery electrolyte rapid osmotic volume core, shorten the production cycle, make the whole production process of lithium ion battery more smooth, enhance productivity.
