Description
また、負極活物質吸収層はアモルファスシリコンから成るとよい。
本発明に係る二次電池用電極の実施例について、図1〜図3を用いて詳細に説明する。本実施例では、二次電池としてリチウムイオン電池を例として説明する。すなわち、本実施例に係る二次電池用電極10は、リチウムイオン電池の負極として用いられる。
以下、本実施例に係る二次電池用電極10(10A,10B)の製造方法について、図3を用いて説明する。
したがって、得られた二次電池用電極10は、炭素系材料2と負極活物質吸収層3との反応を防止することで電気抵抗値の増大を抑制するとともに、電池性能の低下を抑制する。
2 炭素系材料(カーボンナノチューブ)
3 負極活物質吸収層
4 中間層
4a 第1中間層
4b 第2中間層
10(10A,10B) 二次電池用電極
