Microporous Copper Foil

Microporous Copper Foil

New type of current collector: Secondary processing is performed on the basis of the original lithium battery foil, and holes are made by mechanical processing, which can maximize the maintenance of the physical and chemical properties of the foil itself. Used in lithium ion batteries, super capacitors, lithium ion capacitors, etc.

Microporous Copper Foil structure mode
 
1. Full surface micro hole aluminum foil/micro hole copper foil: no side wall for full-width
2. Retaining micro hole aluminum foil/micro hole copper foil: According to the battery design, it can meet the needs of the retaining. It can be divided into the following three types: can be divided into the following three types: both sides can be blocked, both sides + middle ribs, multi-wide ribs
Technical requirements for ribs: In ribs series products, the density of micro hole in the ribs should be less than 10% of the effective hole density.
