Used for lithium-ion batteries
Micro porous copper foilCurrent collector is a commonly used material for manufacturing lithium-ion batteries. Here are some suggestions for choosing microporous copper foil current collectors for lithium-ion batteries:
Corrosion resistance: The microporous copper foil current collector used in lithium-ion batteries should have good corrosion resistance to prevent damage caused by corrosive substances during battery operation.
● Conductivity: When selecting a microporous copper foil current collector for lithium-ion batteries, its conductivity needs to be considered to ensure that the battery can function properly.
● Deformation performance: When selecting a microporous copper foil current collector for lithium-ion batteries, its deformation performance needs to be considered to avoid deformation or damage during long-term use.
Cost: When choosing a microporous copper foil current collector for lithium-ion batteries, its cost needs to be considered to ensure that its price meets market demand.
Micro porous copper foil current collector is a high surface area copper foil made by printing or etching micro pores on the surface, with a large number of micro pores and micro slits, which can meet the high conductivity, high safety, and high heat transfer requirements of lithium-ion battery current collectors.

Micro porous copper foil current collectorThere are two preparation methods: one is anodizing, which uses the anode to oxidize the copper foil surface to form copper oxide to prepare microporous copper foil current collectors; Another method is to prepare by laser etching.
The role of microporous copper foil current collector in lithium-ion batteries is to uniformly mix the active materials of the positive and negative electrodes with conductive agents to form electrode sheets. Then, the electrode sheets are connected to aluminum foil or copper foil electrodes through the current collector, allowing charges to freely flow between the electrodes, thereby achieving the storage and release of lithium ions.
At present, microporous copper foil current collector has become one of the most widely used conductive current collectors in lithium-ion battery production, widely used in fields such as electronics, communication, medical equipment, public transportation, energy storage, etc.
In summary, when selecting a microporous copper foil current collector for lithium-ion batteries, multiple factors need to be considered to ensure that its performance meets the requirements.
