Summary:To improve a coulomb efficiency in an initial charge and discharge cycle.SOLUTION: An anode-less battery 10 comprises: a negative electrode 22 having a negative electrode collector 22a and a lithium deposition layer 22b; a positive electrode 21 having a positive electrode collector 21a and a positive electrode active material layer 21b; a separator 23; and a non-aqueous electrolyte containing a LiN(FSO2)2. On a front surface of the lithium deposition layer 22b, an aluminum containing layer 22c containing a material having an Al-O coupling is formed.SELECTED DRAWING: Figure 1 【課題】初期の充放電サイクルにおけるクーロン効率を向上させる。【解決手段】アノードレス電池１０は、負極集電体２２ａ及びリチウム析出層２２ｂを備える負極２２と、正極集電体２１ａ及び正極活物質層２１ｂを備える正極２１と、セパレータ２３と、ＬｉＮ（ＦＳＯ２）２を含む非水電解質とを備える。リチウム析出層２２ｂの表面には、Ａｌ－Ｏ結合を有する物質を含むアルミニウム含有層２２ｃが形成されている。【選択図】図１
