摘要：
The invention provides a cathode active material for use in a rechargeable battery, comprising a coated lithium nickel oxide powder or a coated lithium nickel manganese oxide powder, the powder being composed of primary particles provided with a glassy lithium silicate surface coating. A method for preparing the cathode active material comprises the steps of: providing a lithium transition metal based oxide powder, providing an alkali mineral compound comprising a Li2−xSiO3−0.5x compound, wherein 0
