Abstract

A hard carbon material has a flake-like structure, where a length of the flake-like structure is denoted as L, and a width of the flake-like structure is denoted as D1, where L satisfies: 2 µm ≤ L ≤ 16 µm; and D1 satisfies: 0.1 µm ≤ D1 ≤ 3 µm. The hard carbon material can have good contact between particles thereof, better processing performance, and a higher gram capacity, thereby further increasing the compacted density of the battery electrode plate, reducing electrode plate resistance, and improving the energy density of the secondary battery while improving the rate performance, and cycling performance of the secondary battery.
