  • Publication number: 20220158188
    Abstract: The present invention provides carbon-coated lithium metal phosphate which is doped with aluminium such that the aluminium content is between 300 and 5000 ppm and which has a BET surface area of less than or equal to 15 m2/g. The carbon-coated lithium metal phosphate finds use as a cathode active material and provides improved electrochemical performance at low temperatures.
