Lithium/thionyl chloride batteries (Li/SOCl2) are widely used because of their advantages of high specific energy and long storage life. Low discharge rate battery is mainly used for storage backup power and other uses requiring long working life, widely used in water meters, gas meters, electricity meters, smoke and anti-theft alarm and intelligent meters, instruments, etc. Large square batteries have been used in the military as emergency backup power, mainly for military backup power independent of commercial power supply and military equipment charging and so on. Medium and high discharge rate batteries have also been developed for various electrical and electronic equipment power supplies, mainly used in naval equipment, such as mines, torpedoes.
Glass fiber separator paper is made of glass fiber with a diameter of 3 μm-5 μm and is manufactured by wet process.The product has good chemical stability, good consistency, good temperature resistance and high safety. It has the function of preventing the short circuit of the positive and negative electrodes and absorbing the required electrolyte. The product effectively improves the energy density and charge-discharge performance of lithium/thionyl chloride battery.
-Good insulation to achieve the effect of isolating the positive and negative electrodes and prevent short circuit of the battery;
-Sufficient chemical stability to avoid corrosion by the battery electrolyte and ensure battery life;
-Sufficient pull The tensile strength and small shrinkage rate effectively prevent the deformation of the diaphragm;
-Good consistency. It not only has good permeability, but also has good wetting ability to the electrolyte, which ensures the lower resistance and higherion conductivity of the separator, thereby to improve the energy density and charge and discharge performance of the battery;
-High Safety. The glass fiber separator has sufficient puncture strength, the highest possible melting temperature and a suitable closed cell temperature, which not only prevents the battery from short circuiting, but also prevents the battery from overheating.
