One of the most common forms of the lithium cell that is more slanted towards consumer use is the one that uses a metallic form of lithium as the anode and manganese dioxide as the cathode, with a small amount of lithium salt to be used as the organic solvent necessary to facilitate the current to travel from the anode to the cathode of the battery.
The new thin sealing technology, which maximizes the battery's interior volume and allows additional space for more active materials, and the use of highly purified and densely packed manganese dioxide and finely granulated zinc, all improve the performance of the battery.
