Title:
POWER STORAGE DEVICE AND CARBON MATERIAL USED THEREFOR
Document Type and Number:
Japanese Patent JP2018011015
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device which can keep a sufficient capacity even if it is used under a low-temperature environment.SOLUTION: A carbon material is to be used for an electrode of a power storage device. The carbon material is 0.3 mL/g or more in meso hole volume, of which the mole ratio of acid functional groups to basic functional groups is within a range of 0.7 to 2.0. A power storage device comprises: a pair of electrodes spaced apart from each other; and a nonaqueous electrolyte solution interposed between the electrodes. Of the pair of electrodes, at least one electrode includes the carbon material.SELECTED DRAWING: None
