Lithium sub-batteries, full name lithium - thionyl chloride batteries, lithium thionyl chloride batteries in all the batteries, are a very unique species. Its voltage is 3.6V. The cathode material is thionyl chloride (thionyl chloride), and also the > Lithium-ion batteries are common in consumer electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses fo electrolyte. This characteristic makes its specific energy very high. Is the highest voltage lithium battery. Storage life can be more than 10 years.
Lithium-thionyl chloride battery cell works: Li / SOCl2 battery to ies are technological evolution from lithium-ion batteries. The primary difference is that the lithium-salt electrolyte is not held in an organic solvent but in a solid polymer composite such as polyethylene oxide or polyacrylonitrile.
The advr lithium as cathode, carbon as a positive, anhydrous lithium tetrachloroaluminate (LiAlCl4) SOCl2 solution as electrolyte, SOCl2 is the cathode active material. LiFePO4-SOCl2 / C negative electrode: 4Li = 4Li + + 4e Positive electrode: 2SOCL2 + 4e = 2SO2 + weight and size benefits of Li-ion but are proven to be far safer in critical situations; coupled with a working life of 1,000 charging cycles, double that of other battery types.

As a result, Li / SOCl2 battery has a more serious voltage hysteresis phenomenon, the hysteresis of the voltage in a few minutes to restore the peak voltage to 95%. The LiCl film formed on the surface of the LiCl layer can be destroyed by the initial voltage of the LiCl / SOCl2 battery after two years storage at 25 , such as short circuit of the battery or intermittent discharge with large current for several times. restore. The products LiCl (white) and S (yellow) were deposited in the positive carbon black, partially blocking the micropores in the positive electrode. On the one hand, some positive expansion, on the other hand hinder the diffusion of the electrolyte, increasing the concentration of polarization, the battery gradually failure.
