Abstract
A composite artificial graphite includes a first graphite and a second graphite. The first graphite includes secondary particles and has a graphite interlayer spacing d002 of 0.33560 nm to 0.33610 nm. The second graphite includes primary particles and has a graphite interlayer spacing d002 of 0.33620 nm to 0.33670 nm. A mass percentage of the first graphite in the composite artificial graphite is 40% to 90%.
