    • A lithium ion secondary battery is provided that suppresses an increase of an internal pressure of a battery caused by gases generated therein so as to suppress battery swelling which is linked to a variation of a thickness of the battery and an increase of a binding force of the battery, and is trouble-free in manufacturing as an on-vehicle battery module, so that a high reliability is provided. The lithium ion secondary battery includes a clathrate compound in a battery container, and the clathrate compound is one or more types of compounds selected from a group consisting of cyclodextrins, calixarenes, and crown ethers. With this configuration, CO gas, CO2 gas, and H2 gas in the battery container are absorbed, and the battery swelling caused by the gases is suppressed.
    • 提供了一种锂离子二次电池,其抑制由其中产生的气体引起的电池内部压力的增加,从而抑制与电池厚度的变化相关联的电池膨胀以及电池的粘合力的增加 电池,并且在作为车载电池模块的制造中是无故障的,从而提供高可靠性。 锂离子二次电池在电池容器中包含包合化合物,并且包合化合物是选自由环糊精,杯芳烃和冠醚组成的组中的一种或多种化合物。 利用这种构造,电池容器中的CO气体,CO 2气体和H 2气体被吸收,并且由气体引起的电池膨胀被抑制。
