20140246619 | DESIGN OF MULTI-ELECTRON LI-ION PHOSPHATE CATHODES BY MIXING TRANSITION METALS - In general, the invention relates to electrode materials, e.g., novel cathode materials with high density, low cost, and high safety. A voltage design strategy based on the mixing of different transition metals in crystal structures known to be able to accommodate lithium in insertion and delithiation is presented herein. By mixing a metal active on the +2/+3 couple (e.g., Fe) with an element active on the +3/+5 or +3/+6 couples (e.g., V or Mo), high capacity multi-electron cathodes are designed in an adequate voltage window. | 09-04-2014 |
