NONAQUEOUS ELECTROLYTE BATTERY, BATTERY PACK AND VEHICLE |
摘要 |
A nonaqueous electrolyte battery includes a negative electrode and a nonaqueous electrolyte. The negative electrode comprises an active material having a lithium ion insertion potential of 0.4V (vs Li/Li+) or more, a conductive agent and a current collector. The nonaqueous electrolyte contains first sultones having an unsaturated hydrocarbon group. A diameter distribution of pores of the negative electrode when measured by mercury porosimetry has a first peak having a mode diameter of 0.01 to 0.2 mum and a second peak having a mode diameter of 0.003 to 0.02 mum. A volume of pores having a diameter of 0.01 to 0.2 mum and a volume of pores having a diameter of 0.003 to 0.02 mum, which are measured by the mercury porosimetery, are 0.05 to 0.5 mL and 0.0001 to 0.02 mL, respectively, per g of the negative electrode excluding the current collector. |
