Fig. 5: Demonstration of large-scale production of NVOPF/KB composite and prototype 26,650 full-cell performance.

a The charge–discharge profiles of mass-manufactured NVOPF/KB cathode and commercial hard carbon anode. Inset: the as-synthesized kilogram-scale NVOPF/8% KB products (left) and the preparation of the slurry (right). b Photograph of 26,650 prototype cells. Inset: the weight of a prototype 26,650 battery. c Rate capabilities of 26,650 cell from 0.1 to 5C. d Cycling performance of 26,650 cell at 3C.
