Steel shell battery" target="_blank">lithium battery

Early lithium-ion batteries were mostly steel casings. Due to the large weight of the steel shell, the safety is poor, but the stability of the steel is strong, many manufacturers through the safety valve, PTC and other devices to optimize the design structure, greatly increased its safety performance. Some, such as today's mobile phone batteries, have replaced steel with aluminum and soft packaging.

Aluminum shell lithium battery

Aluminum-shell lithium-ion battery is lighter and safer than steel-shell lithium-ion battery.

Flexible packaging lithium battery

Flexible packaging lithium-ion battery is gradually expanding its market share due to its advantages of light weight, low die opening cost and high safety.
