AI Technical Summary
Technical Problem
Existing rechargeable batteries are prone to pullback of electrode assembly and resulting impact damage when they fall, and tape cannot effectively prevent these problems.
Method used
By using an adhesive to form a bonding portion on the outside of the separator of the electrode assembly and the electrode plate, the adhesive is applied on at least one surface facing the housing to fix the electrode plate and the membrane to prevent pullback and reduce impact.
Benefits of technology
Effectively prevent or reduce the pullback of the electrode assembly when it falls, and reduce damage caused by impact, improving the durability of the battery.
