正極活物質層20は正極活物質を含み、正極活物質としては、リチウムと遷移金属との複合酸化物、遷移金属酸化物、遷移金属硫化物、PbO2、AgOまたはNiOOHなどを用いることができる。
負極活物質層30は負極活物質を含み、負極活物質としてはTiO、Ti2O3TiO2またはSnO2などの金属酸化物、Li4/3Ti5/3O4、またはLi7MnNなどのリチウムと遷移金属との複合酸化物、Li−Pb系合金、Li−Al系合金、Li、およびCからなる群より選択される少なくとも1種などが挙げられる。
イオン伝導層10は、全固体高分子からなるセパレータに電解質をしみ込ませることによって形成され、正極活物質層と負極活物質層とを電気的に絶縁するとともに、放電時には負極活物質層から正極活物質層に流れるイオンを通過させ、充電時には正極活物質層から負極活物質層に流れるイオンを通過させる。セパレータは特に限定されないが、ポリプロピレン、またはポリオレフィンなどが挙げられる。これらは不織布または微多孔膜などの電解液を通過させる形状で用いられうる。
集電体の材質は、特に限定されないが、ニッケル、ステンレス、鉄、チタン、アルミニウム、タンタル、ニオブ、ハフニウム、ジルコニウム、亜鉛、タングステン、ビスマス、および銅からなる群より選択される少なくとも1種が挙げられ、より好ましくはニッケルまたはステンレスであり、さらに好ましくはステンレスである。
