摘要：The present invention provides a carbon material for use in an electrode of a nonaqueous secondary battery which shows excellent properties and combines high-rate charge/discharge characteristics and high cycle characteristics. Furthermore, a subject for the invention is to shorten the time period required for an absorption of an electrolyte and to thereby shorten battery production steps and reduce the cost of battery production. A carbon material for nonaqueous-electrolyte secondary-battery negative electrode is provided, which satisfies the followings (1) and (2): (1) the carbon material has an aspect ratio of 10 or less; (2) the amount of CO eliminated from the carbon material during heating to 1,000°C, as determined with a temperature programmed decomposition mass spectrometer (TPD-MS), is 2-15 µmol/g.
