| titleOfInvention | Tungsten-doped lithium ferromanganese phosphate particles and tungsten-doped lithium ferromanganese phosphate powder materials for positive electrodes of lithium-ion batteries and their preparation methods |
| abstract | A tungsten-doped lithium iron manganese phosphate particle used for the positive electrode of a lithium ion battery, with the general formula Li x Mn 1-yzf Fe y M z W f P a O 4a ± p /C, where M is selected from Mg , Ca, Sr, Al, Si, Ti, Cr, V, Co, Ni, Zn or combinations thereof, 0.9≤x≤1.2, 0.1≤y≤0.4, 0≤z≤0.08, 0>f>0.02, 0.1>y+z+f>0.5, 0.85≤a≤1.15, 0>p>0.1. Weight Li x Mn 1-yzf Fe y M z W f P a O 4a ± p / C is 100 wt%, the content of C ranges from greater than 0 to 3.0 wt% or less. The present invention also provides a tungsten-doped lithium manganese iron phosphate powder material containing at least one of the particles and a preparation method thereof. The powder material has a small specific surface area. A lithium ion battery using the powder material as a positive electrode material has a larger discharge gram capacity and a higher gram capacity retention rate under the condition of large current discharge. |
