METHOD OF IMPROVING SAFETY OF NONPRESSURE TYPE CHEMICAL BATTERY

摘要

The safety of a non-pressurized electrochemical cell such as a Li/MnO2 cell, having a safety pressure vent and an organic electrolyte solvent is enhanced by, in conjunction with said vent, providing said organic electrolyte solvent with at least 80% by volume of a volatile component, such as dimethoxyethane, having a boiling point between 30 DEG C. to 130 DEG C. Upon cell venting, under abuse conditions, the cell is thereby rapidly evacuated and safely rendered inoperable under further abuse conditions.
