Abstract
A battery pack is provided in which battery characteristics are not degraded in normal use and, even if a cell reaches a high temperature and a high-temperature gas is released from the inside of the cell, the spread of combustion to the entire pack can be suppressed to reduce damage. The battery pack is provided with cells, a housing for accommodating the cells and a thermal expansion section capable of reducing internal clearances between the cells and the housing upon the application of heat.
