Description
Porous aluminum foil current collector is based on the current commonly used ordinary current collector or coated carbon sets, on the base of current collector, to solve the current collector to reduce weight. improve the utilization rate of active material, improve the electrode conductive ability reduce the polarization, enhance battery power density and energy density is developed by a new set aperture is50~100 um current collector products. At the same time, the current collector can be used to solve the problem of effective migration of lithium ions. This product can effectively improve the first charge and discharge efficiency of the battery. the charging and discharging capacity of the large ratio, the cycle service life and make an important contribution to the high energy density quick charge battery.
Advantage：
◎ Reduces the weight of current collector.
◎ lmprove the active substance and the adhesion of current collector.
◎ Reduce interface resistance and reduce battery resistance.
◎ Reduce polarization, increase battery rate charging and discharging performance and active material gram capacity play.
◎ Reduce heat of battery, improve battery safety.
◎ Increase the migration rate of lithium ions.
◎ Improve battery energy density.
