摘要:
The present invention provides: (i) a nonaqueous electrolyte for batteries, which is characterized by containing halogen; (ii) a nonaqueous electrolyte for batteries, which is characterized by containing pyrrol or its derivative and halogen; and (iii) a lithium secondary battery which is characterized by including the nonaqueous electrolyte (i) or (ii). The inventive lithium secondary battery has improvements in charge/discharge and cycle life characteristics at ambient and high temperatures, and/or storage characteristics and safety at high temperature.
摘要:
Disclosed are a safety element for a battery, which is provided with material having a Metal-Insulator Transition (MIT) characteristic where resistance abruptly drops at or above a certain temperature, and a battery with such a safety element. This battery with an MIT safety element is turned into a stable discharged state when it is exposed to an elevated temperature or a battery temperature rises due to external impact, so that it can ensure its safety.
