A 5 L beaker was charged with 2 L of ion-exchanged water, and 252 g of lithium hydroxide was added to the beaker, and dissolved. After the addition of 364 g of vanadium pentoxide to the solution, the mixture was stirred for 1 hour. After the addition of 72 g of glucose and 692 g of 85% phosphoric acid to the mixture, the mixture was stirred for 1 hour to obtain a raw material mixture. The raw material mixture was supplied to a spray dryer (hot blast inlet temperature: 230° C., hot blast outlet temperature: 120° C.) to obtain a spray-dried product. The spray-dried product was placed in a saggar made of mullite, and calcined at 900° C. for 12 hours in a nitrogen atmosphere. The calcined product was disintegrated using a jet mill to obtain a lithium vanadium phosphate-carbon composite sample. FIG. 5 shows the particle size distribution measurement results for the lithium vanadium phosphate-carbon composite sample.
