An anode and a battery, which have a high capacity and can improve battery characteristics such as large current discharge characteristics and low temperature discharge characteristics are provided. An anode has an anode current collector and an anode active material layer provided on the anode current collector. The density of the anode active material layer is in the range from 1.5 g/cm3 to 1.8 g/cm3. Further, the anode active material layer contains a granulated graphite material which is obtained by granulating a flat graphite particle in nodular shape and mesocarbon microbeads. Thereby, the granulated graphite material is prevented from being destroyed, and diffusion path of lithium ions is secured. |
