  • Lithium Ion Battery
    Publication number: 20160006077
    Abstract: A high-input and high-output battery having a large capacity while guaranteeing safety is provided. As a composition of an electrolytic solution, a composition ratio of ethylene carbonate (EC) is 20 vol % or more and 30 vol % or less, and a composition ratio of dimethyl carbonate (DMC) is 36 vol % or more and 50 vol % or less, and a composition ratio ? (DMC/EMC) of dimethyl carbonate (DMC) and ethyl methyl carbonate (EMC) is 1.0???1.7. Furthermore, a composition ratio of an additive is 0.1 wt. % or more and 1.0 wt. % or less, and a concentration of lithium salt is 1.0 mol/L or more and 1.5 mol/L or less.
