Title:
LITHIUM ION BATTERY AND ELECTRONIC DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/136722
Kind Code:
A1
Abstract:
This nonaqueous electrolyte lithium ion battery (E) comprises a positive electrode terminal (1), a negative electrode terminal (2) and a battery case (3), and an electrode body (10) is contained within the battery case (3). The electrode body (10) comprises a positive electrode collector (11), an electrode plate (12) for positive electrodes, a negative electrode collector (13) and an electrode plate (14) for negative electrodes. The electrode plate (12) for positive electrodes and the electrode plate (14) for negative electrodes are laminated with a separator (15) being interposed therebetween. A CO and CO2 adsorbent is disposed within the battery case (3) of this lithium ion battery (E). An LSX zeolite, X zeolite or A zeolite can be used as the adsorbent. In particular, an A zeolite ion-exchanged with Ca is preferable in terms of renewability in cases where the gas adsorbent adsorbs moisture and the gas adsorption performance thereof is decreased. A lithium ion battery according to the present invention is capable of reducing deformation of an air-tight container accompanying increase of the internal pressure due to a gas component such as CO or CO2, which is generated within the battery at the time of abnormality or during a long period of use.
