- •
Thermal generation behavior of 18650 NCM523 batteries is investigated.
- •
The decreased thermal effect is ascribed to the increased internal resistance.
- •
The high environment temperature also leads to a capacity fading obviously.
- •
The crystal/nano structure of the cathode is destroyed at high temperature.
