Researchers in South Korea have developed an additive that prevents the degradation of electrodes in large-capacity lithium-ion batteries by heat.
Teams from The Daegu Gyeongbuk Institute of Science and Technology (DGIST) and Dongguk University developed the additive, reported South Korean media outlet Aju Business Daily.
The electrolyte additive uses lithium tetrafluorophosphate (LFMP) to create a protective layer on the cathode and anode of batteries.
The researchers say the protective layer boasts electrode performance after 250 cycles in about 600 Celsius (1400 Fahrenheit).
The additive also helped the battery maintain its initial charge voltage for 80 days, noted the report.
DGIST aims to develop the additive so it can be immediately added to commercial lithium-ion batteries.
