摘要：A battery capable of improving cycle characteristics is provided. An anode active

material layer is formed by a vapor phase method, and includes Si as an element. In theanode active material layer, a plurality of primary particles formed by growth in athickness direction are included, and the plurality of primary particles are agglomeratedto form a plurality of secondary particles. Each secondary particle is separated by agroove formed by charge and discharge, and some of primary particles are split particlessplit by the groove. The average number of the split particles per secondary particle in 5or more adjacent secondary particles is 10 or more. Moreover, the primary particles andthe secondary particles are inclined to the same side.
