Why Li Polymer Batteries Bump Up?

Shenzhen Sinoli Electronic Co.,Ltd | Updated: Nov 25, 2018

Why Li Polymer Batteries Bump up?


There are impurities in the production process; there are problems with SEI; there is water in it.


From the point of view of technology, the following aspects can be considered:


1. It is better to use the opening material at the same time. It is suggested that the material should be packaged with aluminium-plastic film. The material should be baked at high temperature and vacuum for more than 12 hours before use.


2. Control of moisture content in the baking of coated posterior pole sheet and core baking;


3. The batteries need to be aged at high temperature for more than 24 hours after injection.


4. The limitation of voltage and current is relatively high. I haven't studied it yet. I don't have any reference data. I need to explore it myself.


5. In battery design, 1:1 is recommended for the matching of positive and negative capacities.


6. The chemical component capacity of the soft-pack battery can be clamped up, and then degassed and sealed.
