MATERIAL FOR ELECTRODE OF POWER STORAGE DEVICE, POWER STORAGE DEVICE, AND ELECTRICAL APPLIANCE |
摘要 |
To improve the reliability of a power storage device. A granular active material including carbon is used, and a net-like structure is formed on part of a surface of the granular active material. In the net-like structure, a carbon atom included in the granular active material is bonded to a silicon atom or a metal atom through an oxygen atom. Formation of the net-like structure suppresses reductive decomposition of an electrolyte solution, leading to a reduction in irreversible capacity. A power storage device using the above active material has high cycle performance and high reliability. |
