6 FAQs about [Lithium battery overcharge internal temperature drops]

How to improve overcharge performance of lithium-ion batteries?

Rupture of the pouch and separator melting are the two key factors for the initiation of TR during overcharge process. Therefore, proper pressure relief design and thermal stable separator should be developed to improve the overcharge performance of lithium-ion batteries.

What causes a battery to overcharge at a low temperature?

At low temperature, the overcharge degree will be the minimum within the upper and lower limits of normal charging, and too high voltage will cause the overcharge degree to increase. The temperature and overcharge degree of different batteries during thermal runaway at a 1.00 C rate

Why is the initial runaway temperature of a lithium battery high?

The initial runaway temperature of 2.00 C overcharge is slightly higher than 1.50 C, which may be because in the later stage of 2.00 C charging, under the limitation of the battery limit current density, there is no excess charge, resulting in the decrease of lithium evolution, so the thermal stability of the battery is also relatively high.

What happens if the battery temperature drops sharply?

After the temperature drops sharply, the battery is a completely thermal runaway, and the overcharge degree decreases slightly or remains unchanged. It can be seen from the figure (b) that the overcharge degree of 32,650 battery increases slightly before reaching the initial runaway temperature.
