Steel-shelled lithium-ion batteries

In the early days, angular lithium-ion batteries were mostly steel shells, mostly used in mobile phone batteries, and later due to the low weight specific energy of steel shells and poor safety, they were gradually replaced by aluminum shells and flexible packaging lithium-ion batteries. At present, there are still some small factories that use steel shells to make B mobile phone batteries and some low value-added MP3 and MP4 batteries.

But in the column lithium-ion battery, there is another scene, most manufacturers are using steel as the battery shell material, because the physical stability of the steel material, the pressure resistance is much higher than the aluminum shell material, after the design structure of each manufacturer is optimized, the safety device has been placed inside the battery cell, the safety of the steel shell column battery has reached a new height, you don't see that most of the current notebook computer battery cells are made of steel shell as the carrier.

Flexible packaging lithium-ion batteries

Flexible packaging lithium-ion batteries are gradually expanding their market share due to their light weight, low mold opening cost, and high safety. It is mainly used in digital products, and is gradually developing into the market of mobile phones, laptops, power tools, etc. It is foreseeable that in the next few years, the market share of flexible packaging lithium-ion batteries will continue to expand steadily, and the scope of use is more extensive.
