More Information
Summary:The invention discloses a positive electrode of a high temperature lithium thionyl chloride battery. The positive electrode is composed of acetylene black, copper powder, a teflon emulsion, a chlorine containing macromolecule binder and a solvent in the mass ratio of 10 to 0.8 to (0.2-0.5) to (0.3-0.7) to 45.5. The positive electrode particles of the high temperature lithium thionyl chloride battery provided by the invention can keep spherical in electrolyte and can gather together, so that transfer resistance of reaction ions and electric charges in the multi-hole electrode is effectively reduced, the concentration polarization in a reaction process is alleviated, a discharging platform is improved, and voltage lag is relieved.
