Abstract
A positive-electrode material includes lithium vanadium phosphate particles having an average primary particle diameter from 0.3 μm to 2.6 μm and crystallite sizes from 24 nm to 33 nm. The lithium vanadium phosphate particles are coated with a conductive carbon of a range of 0.5 mass % to 2.4 mass % with respect to a total lithium vanadium phosphate particles.
Claims9
A positive-electrode material comprising:
- lithium vanadium phosphate particles, an average primary particle diameter of which is 0.3 μm or more and 2.6 μm or less, and crystallite sizes of which are 24 nm or more and 33 nm or less,
- wherein a crystallization degree of the lithium vanadium phosphate particles is 98% or more, and
- wherein the lithium vanadium phosphate particles are coated with a conductive carbon of a range of 0.5 mass % to 2.4 mass % with respect to a total mass of the lithium vanadium phosphate particles.
