Batteries Protection

Safety Hazard of Lithium ion batteries

The Lithium ion batteries can hardly work stably in special conditions under  puncture, collision, large temperature variations, significantly high or low temperature. External impacts on the batteries may result in short circuit, electrolyte leakage, fire and even explosion, causing safety risks for human, properties, and polluting environment.

· 2016 - Sony battery explosion resulted in massive recalls from around the globe at huge costs.

· 2007 - Nokia recalled 46 million pieces of batteries related to 52 types from the whole world.

· 2012 - May 26 BYD electric mobile fire break-out caused death of the driver and two passengers.

· 2013 - Boeing 787 suspended for flights globally due to a Lithium battery failure.

· 2013 - Battery fire of Tesla Model S cars occurred for three times in six weeks.

Solution: Battery packaging with nanomaterials

The multi-functional battery package made of nano-mesoporous materials by our patented technologies can solve a series of safety problems: resistance to collision by absorb contact energy, instant absorption of leaked electrolyte, heat insulation and extension of battery lifetime.


Three characteristics :


absorption of energy

absorb 3000-20000 joules of energy generated during collision, significantly reducing fire probability.


absorption of fluid

rapidly absorb the leaked electrolyte and effectively prevent fire and environmental pollution.


heat insulation

reduce the effects of external temperature variation and expand the working temperature range for Lithium batteries.
