Polyacetylene solid-state batteries
The present report summarizes the performances of the solid-state batteries using a superionic conductor as solid electrolyte and polyacetylene as electrode material. Two types of cells have been tested. A first class uses the mixed ionic solid RbAg/sub 4/I/sub 5/ together with a silver anode. The second one uses ..beta.. /SUP ''/ -Al/sub 2/O/sub 3/, /chi/Na/sub 2/O together with sodium-doped (CH) /SUB lx/ . Both fulfill the objective of being able to discharge at room temperature. In addition to the usual performances such as voltage, current, capacity, weight, shape, etc., we give the results over 4 yr of investigations on the discharge life and storage life. Many practical problems have been encountered, especially in the case of the sodium-polyacetylene battery. They are also reported, as well as some improvements made during that period such as encapsulation, diffusion inhibitors, and separation of the components until the first charge. The conclusion is that polyacetylene is proved to be a useful electrode material in solid-state batteries at the laboratory level. The possible further development to reach the industrial stage is discussed in terms of lifetime energy, density, and cost.
