     4-micron ultra-thin lithium battery copper foilMicro porous copper foil is two different copper foil materials that are suitable for different application scenarios. 4-micron ultra-thin lithium battery copper foil is a very thin copper foil material commonly used to manufacture electrodes for lithium batteries.
Due to the high specific energy and power density required for lithium batteries, electrode materials need to have high conductivity and high specific surface area. Ultra thin copper foil can provide a larger specific surface area, thereby improving the efficiency and performance of the electrode.
     Micro porous copper foilIt is a copper foil material with micro pores, commonly used for manufacturing micro devices such as micro filters, microfluidic chips, and micro heaters. The pore size of microporous copper foil can be adjusted between a few micrometers to several hundred micrometers, with good filtration and heat transfer performance, enabling precise fluid and temperature control.

4-micron ultra-thin lithium battery copper foil and microporous copper foil are also commonly used materials in lithium-ion batteries, mainly used to manufacture electrolyte copper foil for batteries.
