CATHODE COMPOSITIONS FOR LITHIUM ION BATTERIES |
| 摘要 |
A cathode composition for a lithium ion battery that contains lithium having the formula (a) Li¿y<[M?1¿¿(1-b)?Mn¿b?]O¿2? or (b) Li¿y?[M?1¿¿(1-b)?Mn¿b?]O¿1.5+C? where 0<=y<1, 0<b<1 and 0<c<0.5 and M?1¿ represents one or more metal elements, with the proviso that for (a) M?1¿ is a metal element other than chromium. The composition is in a form of a single phase having an O3 crystal structure that does not undergo a phase transformation to a spinel crystal structure when incorporated in a lithium-ion battery and cycled for 100 full charge-discharge cycles at 30C and a final capacity of 130 mAh/g using a discharge current of 30 mA/g. |
