Microporous aluminum foil
Product performance and use: a new type of current collector, secondary processing on the basis of the original lithium battery foil, using mechanical processing to make holes, which can maximize the maintenance of the physical and chemical properties of the foil itself.

|
Energy Density |
After perforating, it produces a weight reduction effect (the same area of the foil, the weight is reduced by 17%),At the same time, it can accommodate more positive and negative materials, and the energy density is 3.5%~8% higher than the existing foil |
|
Rate performance |
The coating materials on both sides of the current collector form a whole, the electrolyte can be fully infiltrated, the lithium ion migration path is changed from a two-dimensional diffusion mode to a three-dimensional longitudinal direction that complements each other, and the lithium ion migration efficiency is improved. |
|
Cycle life |
The electrodes made of microporous foils form a complete "I" type occlusion through the pores on the front and back to prevent the electrode material from falling off after long-term charging and discharging, and effectively improve battery life. |
|
Safety performance |
Lithium dendrites are one of the main culprits leading to safety accidents of lithium-ion batteries. The lithium ions on both sides of the microporous current collector can play a self-balancing effect due to the presence of micropores, which can effectively alleviate the phenomenon of lithium evolution caused by uneven coating and improve safety performance. |
