Abstract

The invention provides an elliptic dynamic lithium ion battery, comprising a shell, a top cover of the shell, a bottom cover of the shell, wherein a roll core is arranged in the shell; the top cover of the shell is provided with a positive electrode pillar and a negative electrode pillar; the upper end of the roll core is provided with a negative electrode flow collecting ring corresponding to the negative electrode pillar; and the lower end of the roll core is provided with a positive electrode flow collecting ring corresponding to the positive electrode pillar. The invention has the advantages that the elliptic dynamic lithium ion battery can reduce current resistance when discharging, and has simple structure and low cost.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to an elliptical power lithium ion battery. Background technique [0002] Lithium-ion batteries are developed from lithium batteries. The positive electrode material of lithium batteries is manganese dioxide or thionyl chloride, and the negative electrode is lithium. After the battery is assembled, the battery has voltage and does not need to be charged. This battery can also be charged, but the cycle The performance is not good. During the charging and discharging cycle, lithium dendrites are easy to form, causing the internal short circuit of the battery. Therefore, charging of this battery is generally prohibited. Later, a lithium battery with a carbon material as the negative electrode and a lithium-containing compound as the positive electrode appeared. During the charge and discharge process, there is no metal lithium, only lithium ions, which is the lithium ion battery. ...
