  • Electrolyte additive and use thereof in lithium-ion battery
    Patent number: 9812739
    Abstract: The present disclosure discloses an electrolyte additive and its use in a lithium-ion battery. The lithium-ion battery may include an electrolyte solution. The electrolyte solution may include an organic solvent, a lithium salt, and an electrolyte additive. The electrolyte additive may comprise a multi-nitrile compound and a sulfur-oxygen double bond-containing compound. The use of the electrolyte additive in a lithium-ion battery enables the lithium-ion battery to maintain a good cycle life, low-temperature discharge characteristics, and high-temperature storage characteristics even at a high voltage.
