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.
