Japanese researchers recently developed a more secure lithium-ion battery electrolyte, even in the face of high temperature and other environments are not easy to burn or explode. Lithium batteries are widely used in electric vehicles or mobile phones and other electronic devices, but the traditional lithium-ion battery used It is a very flammable organic electrolyte, security risks are serious.
Researchers from institutes such as Tokyo University said in a new issue of the British journal Nature & Energy that they developed a highly concentrated electrolyte containing flame retardant trimethyl phosphate, which is not flammable , And can achieve high stability charge and discharge more than 1,000 times or more than one year, the service life comparable to or even more than the traditional lithium-ion battery.
The research team pointed out that this electrolyte can make lithium-ion battery operating voltage increased from the current 3.7 volts to 4.6 volts, will be suitable for electric vehicles and other high-energy density, high safety requirements of the battery, the research team Will promote the research and related enterprises.
