　　According to foreign media reports, thanks to a study on battery research and development by Australia's top universities Monash University and Toyota Research Institute of North America (TRINA), the performance of high-energy-density batteries may be improved. Toyota Research Institute North America, located in Ann Arbor, Michigan, is a division of Toyota Motor Research North America (TMNA).

　　The new battery material discovered this time is non-volatile, non-flammable and electrochemically stable electrolyte, which can be used in batteries. Technologies such as mobile phones, laptops, hybrid and electric vehicles rely on lithium-ion batteries, which are mainly composed of graphite anodes and cobalt-based cathodes. The electrolytes are often composed of flammable and volatile organic electrolytes. A research team from Monash University and Toyota Research Institute North America has discovered a new electrolyte based on liquid salt that can be used in batteries to eliminate flammability and improve their stability.

　　Professor Doug MacFarlane from Monash University's School of Chemistry said: "We have also found that this type of new electrolyte can be used in rechargeable magnesium metal and lithium metal battery technologies, allowing the use of higher voltage materials in lithium-ion batteries, thereby enhancing the battery's storage capacity. Ability.”

　　"The new material is based on carborane anions and is made of boron clusters," said project leader Rana Mohtadi, a principle scientist at Toyota Research Institute of North America. "Recent research has shown that such materials are very stable and can be used in chemicals such as lithium batteries." We hope to exploit the stability of such ions to create high-energy-density batteries with lithium and magnesium metals. In fact, this is the first time that liquid ions have been shown to be used in magnesium metal batteries."
