Lithium batteries are widely used in electric vehicles or cell phones and other electronic devices, but the traditional lithium-ion batteries are extremely flammable organic electrolyte, security risks 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.
