Summary:Provided is a coated carbon material from which it is possible to obtain a secondary battery exhibiting an excellent initial efficiency and high peel strength. As a result, the present invention addresses the problem of providing a high-performance secondary battery, and the problem is solved by a coated carbon material that is for secondary batteries, that is capable of occluding/discharging lithium ions, and that has, on a carbon material, a specific coating formed from an organic compound. L'invention concerne un matériau carboné revêtu à partir duquel il est possible d'obtenir une batterie secondaire présentant un excellent rendement initial et une résistance au pelage élevée. Ainsi, la présente invention aborde le problème de la fourniture d'une batterie secondaire à haute performance, et le problème est résolu par un matériau carboné revêtu qui est destiné à des batteries secondaires, qui est capable de bloquer/décharger des ions lithium, et qui a, sur un matériau carboné, un revêtement spécifique formé à partir d'un composé organique. 初期効率に優れ、ピール強度が高い二次電池を得ることが可能な被覆炭素材を提供し、その結果として、高性能な二次電池を提供することを課題とし、リチウムイオンを吸蔵・放出可能な二次電池用被覆炭素材であって、炭素材に有機化合物による特定の被膜を有する二次電池用被覆炭素材により課題を解決する。
