| Abstract: | The influences of the synthetic conditions of the positive electrode material Li 1+ x Cr y Mn 2- y O 4 for the secondary lithium ion battery on its structure and electrochemical properties were studied.The experimental results showed that although the Cr substitution reduced the initial capacity,it was beneficial to the cycles of LiMn 2O 4. |
