Abstract
The invention relates to the field of lithium ion batteries, and in particular relates to a device for improving performance of a lithium ion battery. Heat energy is supplied by a heating module, so that the lithium ion battery can work at the temperature of 20-40 DEG C, and thus, the reaction activity of the lithium ion battery is high, and the energy can be fully released. The heating module is a printer, and the heat energy produced during the working of the printer is transferred to a lithium ion battery bin through heat conducting holes so as to increase the temperature of the lithium ion battery bin, thereby ensuring that the lithium ion battery can work at the temperature of 20-40 DEG C as much as possible. A printer bin contacts the lithium ion battery bin, so that the heat transfer is fully improved, and an internal space of the device can be saved.

Background technology
Lithium ion battery has liquid lithium ionic cell (LIB) and polymer Li-ion battery (PLB) two class at present.Wherein, liquid lithium ionic cell refers to that Li+ inlaid scheme is the secondary cell of positive and negative electrode.Positive pole adopts lithium compound-cobalt acid lithium, LiMn2O4, and negative pole adopts lithium-carbon intercalation compound.Lithium ion battery because operating voltage is high, volume is little, quality is light, energy is high, memory-less effect, pollution-free, self discharge is little, have extended cycle life, and is the desirable energy carrier of 21 century development.
Lithium ion battery is generally that use lithium alloy metals oxide is positive electrode, graphite is negative material, uses the battery of nonaqueous electrolyte.Wherein the operation principle of lithium ion battery is as follows:
The reaction that charging positive pole occurs is
LiCoO2==Li (1-x) CoO2+XLi++Xe-(electronics);
The reaction that charging negative pole occurs is
6C+XLi++Xe-＝LixC6；
Rechargeable battery overall reaction: LiCoO2+6C=Li (1-x) CoO2+LixC6;
