The atomic ratio of boron and bismuth to the total of metal atoms other than boron and bismuth is 5-70 times of the atomic ratio in the whole of the secondary particles. Independent claims are also included for the following: (i) an anode for lithium secondary cells containing the positive electrode material and a binder; (ii) a lithium secondary cell comprising the above anode, a cathode and an electrolyte; and (iii) the manufacture of the anode material by forming the raw material mixture into a particle shape, and sintering at a temperature higher than the melting point of the boron and bismuth compounds to form the secondary particles.",
