Alkali-metal based electrode for secondary battery. |
摘要 |
Disclosed is an electrode for secondary battery, which comprises an alkali metal as the active substance carried on a carrier composed of (1) 100 parts by weight of a carbonaceous material satisfying the following conditions: (A) a hydrogen/carbon atomic ratio of less than 0.15 and (B) a spacing (d002) of the (002) plane according to the X-ray wide angle diffraction method of 3.37 ANGSTROM or more and a crystallite size in the c-axis direction (Lc) of 5 ANGSTROM or more, and 0 to 70 parts by weight of a metal capable of forming an alloy with the active substance or an alloy of said metal and (2) 0.1 to 40 parts by weight of a fibrous organic polymer as the binder, which can give a negative electrode having excellent charging and discharging cycle characteristics and good flexibility to obtain secondary battery having large charging capacity. |
