Power aluminum battery foil

Jun 03, 2022

Aluminum foil is widely used in daily life, mainly used in flexible packaging, medicine packs, food packaging and so on. Although aluminum foil has long been used in lithium batteries, its consumption is minimal. Previously, aluminum foil for lithium batteries has not been the main development direction of the aluminum foil industry. The thickness of power aluminum battery foil for lithium-ion batteries ranges from 10 to 50 microns. The commonly used aluminum foils for lithium-ion batteries are mainly 1 series and 3 series. The alloy grades mainly include 1060, 1050, 1235 and 3003 aluminum foil, etc., and the alloy state Mainly O state and H state.

In recent years, the use of lithium batteries has greatly expanded, and the demand for aluminum foil has rapidly increased. At the same time, the technical requirements for Aluminum foil for Lithium battery have greatly increased. Battery foil is becoming an independent aluminum foil variety. Lithium battery aluminum foil is used as a current collector for lithium-ion batteries and can be divided into power lithium battery foil, consumer battery foil, and energy storage battery foil. Among them, power lithium battery foil is currently in the largest demand, and the consumer battery aluminum foil market is basically saturated. Some analysts in the industry believe that in the future, the proportion of aluminum foil for Lithium battery demand will further increase, and the aluminum foil for energy storage batteries will also gradually increase.
