The positive electrode is not particularly limited, and a known positive electrode can be used. For example, a positive electrode current collector, a positive electrode active material, a conductive agent, a binder, and the like are used. Examples of the positive electrode current collector include aluminum and stainless steel. Examples of the positive electrode active material include LiNiVO 4 , LiCoPO 4 , LiCoVO 4 , LiCrMnO 4 , LiCr x Mn 2−x O 4 (0 <x <0.5), LiCr 0.2 Ni 0.4 Mn 1.4 O 4 , LiPtO 3 , Li x Fe 2 (SO 4 ) 3 , LiFeO 2 , LiMnO 2 , LiMn 2 O 4 , LiCoO 2 , LiMn 1.6 Ni 0.4 O 4 , LiFePO 4 , LiNi 1/3 Mn 1/3 Co 1/3 O 2 , LiNi 1/2 Mn 1/2 O 2 , LiNi 0.5 Mn 1.5 O 4 , LiNi 0.8 Co 0.2 O 2 , LiNiO 2 , Li 1 + x (Fe 0.4 Mn 0.4 Co 0.2 ) 1-x O 2 can be used. . Among these, LiMn 2 O 4 , LiCoO 2 , LiFePO 4 , LiCoPO 4 , LiNiPO 4 , LiNi 1/3 Mn 1/3 Co 1/3 O 2 and LiNi 0.8 Co 0.2 O 2 , NCA (= LiNi 0.8 Co 0.15 Al 0.05 O 2 ) is preferred. In order to increase the output, it is preferable to use a material having a high potential of 4 V or more as the positive electrode material. Examples of the material having a high potential include LiCoO 2 (4.2 V), LiCr x Mn 2−x O 4 (0 <x <0.5) (4.2 V), LiCr 0.2 Ni 0.4 Mn 1.4 O 4 ( 4.7V), LiNi 0.5 Mn 1.5 O 4 (4.7V), LiCoPO 4 (4.8V), LiNiPO 4 (5.1V), LiNi 1/3 Mn 1/3 Co 1/3 O 2 (4. 2V), NCA (= LiNi 0.8 Co 0.15 Al 0.05 O 2 ) (4.2 V), and the like.
