    摘要： The object of the present invention is to provide a manufacturing method of carbonaceous material for a negative electrode of lithium ion capacitors, wherein the carbonaceous material is obtained from plant-derived char as a source, potassium and iron are sufficiently removed, and an average particle diameter thereof is small; and a carbonaceous material for a negative electrode of lithium ion capacitors. The object can be solved by a method for manufacturing a carbonaceous material having an average diameter of 3 to 30µm, for a negative electrode of lithium ion capacitors comprising the steps of: (1) heating plant-derived char having an average particle diameter of 100 to 10000µm at 500°C to 1250°C under an inert gas atmosphere containing a halogen compound to demineralize in a gas-phase, (2) pulverizing a carbon precursor obtained by the demineralization in a gas-phase, (3) calcining the pulverized carbon precursor at less than 1100°C under a non-oxidizing gas atmosphere.
