Manganese phosphates and related electrode active materials |
| 摘要 |
The invention provides electrode active materials comprising lithium or other alkali metals, manganese, a +3 oxidation state metal ion, and optionally other metals, and a phosphate moiety. Such electrode active materials include those of the formula:
AaMnbMIcMIIdMIIIePO4
wherein
(a) A is selected from the group consisting of Li, Na, K, and mixtures thereof, and 0<a≦1;(b) 0<b≦1;(c) MI is a metal ion in the +3 oxidation state, and 0<c<0.5;(d) MII is metal ion, a transition metal ion, a non-transition metal ion or mixtures thereof, and 0≦d<0.5;(e) MIII is a metal ion in the +1 oxidation state and 0<e<0.5; and wherein A, Mn, MI, MII, MIII, PO4, a, b, c, d and e are selected so as to maintain electroneutrality of said compound. |
