| 发明名称 | Composite nano porous electrode material, process for production thereof, and lithium ion secondary battery | ||
| 摘要 | This invention provides a nano composite porous electrode material that has high charge-discharge behavior and charge or discharge capacity and a manufacturing method thereof. It also provides a lithium-ion secondary battery using this nano composite porous electrode material. The nano composite porous electrode material according to this invention has a porous structure such that nano-size pores are three-dimensionally connected with each other wherein walls of the pores thereof are composed of olivine type LiMnPO4 and carbon, a specific surface area Sa is 55 m2g−1<Sa<248 m2g−1, an amount of contained carbon Cc is 15.5 wt %<Cc<28 wt % and a diameter of crystallite is less than 39 nm. This enables a high charge-discharge capacity and a fast charge or discharge behavior to be obtained. | ||
