UNIST team develops new electrolyte additive for high-energy-density Li-ion batteries
Researchers at the Ulsan National Institute of Science and Technology (UNIST) in Korea have developed an innovative electrolyte additive that enables a high-energy-density Li-ion battery to retain more than 80% of its initial capacity even after hundreds of cycles.
When this additive was added to a large-capacity battery composed of a high-nickel anode and a silicon mixed anode, the initial capacity was maintained at 81.5% even after 400 charging and discharging cycles 10% to 30% better than commercial additives such as FEC (fluoroethylene carbonate) or VC (vinylene carbonate).
An open-access paper on their work is published in
