New Energy Battery Explosion-proof Cap

Are lithium batteries prone to thermal runaway?

Despite the rapid progress in material development and technology for higher-energy-density and safer lithium batteries, current lithium battery technology is still exposed to the risk of thermal runaway, although the probability is relatively low.

Can Li-ion battery thermal runaway protection be encapsulated?

An encapsulated method is proposed for largescale Li-ion battery thermal runaway protection. A series of nail penetration experiment are conducted for thermal abuse analysis. Data-intensive modeling is designed for single and 10 cell pack thermal abuse simulation.

Are explosion-proof cells safe?

While the cells enclosed in an explosion-proof box are considered to be safe, there are reports that the thermal runaway propagation from a single cell will ignite the space within the enclosure to a pressure far beyond its limit [12, 18, 19].

Can encapsulation prevent cascaded thermal runaway?

Encapsulation method can effectively dissipate heat and prevent cascaded thermal runaway. The catastrophic consequences of cascading thermal runaway events on lithium-ion battery (LIB) packs have been well recognised and studied.

How is heat dissipated from a battery thermal runaway?

The heat generated by battery thermal runaway is dissipated in three forms of heat transfer: thermal conduction in encapsulation and enclosure; thermal convection and radiation in the upper part and outside of the enclosure.
