Li-ion batteries are one of the most potential candidates as the energy storage devices mainly due to their high energy densities with fairly good rate capabilities and a fairly long cycle life.  Currently, Lithium-ion batteries are nearing their theoretical energy density limit and battery manufacturers are beginning to focus on improving manufacturing methods and increasing safety. In this presentation, I will introduce Microvast’s non-flammable battery technology for lithium-ion batteries resolves battery safety issues through a multi-level approach from materials to the system level. The new technology takes both active and passive protection measures in order to enhance product safety, including improvements to the battery's electrolyte, separator and protection system.  Meanwhile, the fast charging and superb cycle life are maintained for the automotive application. The nonflammable, fast charging & superb cycle life battery technology can solve the current key constraints in electric vehicle development and to redesign electric vehicle power systems to the mass adoption of electric vehicles.
