Abstract
집전체 위에 실리콘층을 형성하고, 실리콘층 위에 리튬을 포함한 용액을 도포하여, 열처리를 행함으로써, 실리콘층 중에 적어도 리튬을 도입시킬 수 있다. 리튬을 포함한 용액을 이용함으로써, 복수의 실리콘의 미립자로 형성된 실리콘층이어도, 미립자와 미립자의 간극에 리튬을 포함한 용액이 들어가, 리튬을 포함한 용액에 접촉한 실리콘의 미립자에 리튬을 도입시킬 수 있다. 또한, 실리콘층이 박막의 실리콘인 경우에도, 혹은 복수의 위스커나 위스커군을 포함하는 실리콘층인 경우에도, 용액을 균일하게 도포하는 것이 가능하고, 용이하게 실리콘에 리튬을 함유시키는 것이 가능하다.
