Description
Technical field
The utility model relates to technical field of lithium batteries, especially with regard to a kind of ternary fast charge lithium battery.
Background technique
Ter-polymers lithium battery refers to that positive electrode uses lithium nickel cobalt manganese or the tertiary cathode material of nickel cobalt lithium aluminate
Lithium battery, compared to traditional lead storage battery, it have energy density it is higher the service life is longer, voltage rating is higher, from
Many advantages, such as discharge rate is lower, while quality is lighter, energy conservation and environmental protection.But there are still no small security risks for it, and at present one
The lithium battery of a little ternary fast charging types, structure do not do any processing to shell, so in such a way that shell directly wraps up battery core
It is steady because of lithium battery because some emergency cases are likely to result in falling for battery and during taking or transports cell
Qualitative difference, hard shell can not play good buffer function, the shock of unbearable big degree to battery, therefore fall
Battery pole is easy to damage, and security risk lithium battery is also increased while wasting cost.
In addition, because charging rate is fast, often there are the excessively high feelings of temperature in the charging or use process of ternary lithium battery
Condition, this is obviously shortened the service life of battery.Existing technical solution is to increase coolant liquid in inside battery to be cooled down, the party
The defect of method is that coolant liquid is easily caused to leak and make cell damage when battery is hit.
Summary of the invention
In view of this, the utility model is to solve excessively high existing lithium battery charging temperature, Yi Fare and intolerant to the skill fallen
Art problem provides a kind of ternary fast charge lithium battery.
