Claim Text:
1. A porous carbon material, comprising: a porous carbon structure having a plurality of macropores, a plurality of mesopores and a plurality of micropores, wherein each of the macropores has a diameter larger than 50 nanometers, each of the mesopores has a diameter ranging from 2 nanometers to 50 nanometers, and each of the micropores has a diameter less than 2 nanometers, wherein based on the total pore volume of the porous carbon structure, a distribution proportion of the pore volume of the macropores ranges from 10-25%, a distribution proportion of the pore volume of the mesopores ranges from 20-80%, and a distribution proportion of the pore volume of the micropores ranges from 0.01-20%, wherein the mesopores have three main pore diameters, wherein the three main pore diameters are 2-4 nm, 5-15 nm and 20-50 nm, respectively, wherein based on the total pore volume of the mesopores, a distribution proportion of the pore volume of the mesopores with the diameter of 2-4 nm ranges from 5-20%, a distribution proportion of the ore volume of the mesopores with the diameter of 5-15 nm ranges from 15-35%, and a distribution proportion of the pore volume of the mesopores with the diameter of 20-50 nm ranges from 20-40%.
