Ion battery has many advantages, such as that energy density is high, light-weight, metamorphosis is more, can be made into ultra-thin battery, therefore current electronics
Mobile product majority is using flexible packing lithium ion battery as the energy.
Because tab is aluminium strip in the battery core anode ear of conventional material, because postorder processing needs, most flexible-packed batteries
A necessary process be that aluminium-to-nickel is carried out to anode.The anode ear that some cell production companies are directly taken a turn for the better using aluminium-to-nickel,
Some cell production companies carry out turning nickel when cell package is completed.When both anode ears turn nickel, the top edge and pole of nickel strap
The distance of ear glue is larger.One necessary operation of two ways are as follows: the fixed tab of rubberizing and folding tab.This nickel mode of turning
Anode ear and production method easily lead to the problems such as thin battery core head super thick, tab deflection, high tab fracture ratio.
