release time:2024-03-08 Hits:     Popular:AG11 battery

  

  1. Good safety performance

  The soft-pack battery is structurally packaged with aluminum-plastic film, and in the case of safety hazards, the soft-pack battery will only burst open at most, rather than explode like the steel-shell aluminum shell cell.

  2. Light weight

  The weight of the soft pack battery is 40% lighter than that of the steel shell lithium battery of the same capacity, and 20% lighter than the aluminum shell battery.

  3. Large capacity

  The capacity of the soft pack battery is 10 ~ 15% higher than that of the steel shell battery of the same size, and 5 ~ 10% higher than that of the aluminum shell battery.

  4. Low internal resistance

  The internal resistance of the soft pack battery is small, and the internal resistance of the domestic soft pack battery core can be as little as 35mΩ, which greatly reduces the power consumption of the battery.

  5. Flexible design

  The shape of the soft pack battery can be customized according to the needs of customers, and new cell models can be developed.

  However, the existing soft pack lithium battery cell models are less, can not meet the market demand; At the same time, developing new models is costly.
