Abstract
In order to increase the electrochemical stability of a cathode material for lithium cells, the cathode material includes an iron-doped lithium titanate. A method for manufacturing a lithium titanate includes: a) calcinating a mixture of starting materials to form an iron-doped lithium titanate; and b) at least one of electrochemical insertion and chemical insertion of lithium into the iron-doped lithium titanate.
