Title (EN) ELECTRODE MATERIAL FOR SECONDARY CELL
(FR) MATÉRIAU D'ÉLECTRODE POUR BATTERIE SECONDAIRE
(JA) 二次電池用電極材料
Abstract: front page image
(EN)The present invention is a novel silicon-containing electrode material for a secondary cell. This electrode material for a secondary cell includes a silicon-based material containing at least sialon. The sialon may include β-sialon. Since the sialon stores and releases lithium ions, this electrode material for a secondary cell is suitable for use as an electrode active material for a lithium-ion secondary cell.
(FR)La présente invention concerne un nouveau matériau d'électrode contenant du silicium pour une batterie secondaire. Ce matériau d'électrode pour une batterie secondaire comprend un matériau à base de silicium contenant au moins un alliage de sialon. Le sialon peut comprendre du sialon β. Etant donné que le sialon stocke et libère des ions lithium, ce matériau d'électrode pour une batterie secondaire s'avère approprié pour servir de matériau actif d'électrode pour une batterie secondaire au lithium-ion.
(JA) 本発明は、珪素を含む新規の二次電池用電極材料である。本発明の二次電池用電極材料は、少なくともサイアロンを含む珪素系材料を含有する。サイアロンは、β-サイアロンを含むとよい。本発明の二次電池用電極材料は、サイアロンがリチウムイオンを吸蔵および放出するため、リチウムイオン二次電池の電極活物質として好適に用いられる。
