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.
