主权项 1. An anode active material comprising at least one iron oxide selected from the group consisting of amorphous iron oxides, ferrihydrite, and lepidocrocite, the at least one iron oxide comprising iron and oxygen as main components, and further comprising silicon and/or phosphorus, the at least one iron oxide having an elemental ratio of iron to silicon or phosphorus of 60-99.9:40-0.1 by atomic percent, with the proviso that the total of iron and silicon or phosphorus by atomic percent is taken as 100, or the at least one iron oxide having an elemental ratio of iron to silicon to phosphorus of 66-87:2-27:1-32 by atomic percent, with the proviso that the total of iron, silicon, and phosphorus by atomic percent is taken as 100.
