Abstract
An inorganic electrolyte rechargeable electrical storage cell is shown which makes use of non-metallic electrodes in combination with an inorganic electrolyte that includes sulfur dioxide. The electrolyte can be for example a lithium and/or a calcium tetrachloroaluminate salt in sulfur dioxide. The anode of the cell is made of a carbon for example a graphite while the cathode is produced from a carbon having a relatively much higher surface area.
