Commutator (electric) A commutator is a moving part of a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.
The word equation that would represent the formation of lithium oxide from lithium metal and oxygen is: lithium + oxygen to lithium oxide. In chemical symbols, the balanced chemical equation is expressed as: Li + O2 = Li2O.
2. The battery according to claim 1 wherein said lithium copper oxide is represented by the nominal formula Li 2-x CuO 2 and deintercalates a quantity x of lithium ions for transfer to said negative electrode, where x is greater than 0 and less than or equal to 2.he lithium hydroxide is of the formula LiOH and the copper oxide starting material formula is CuO. The copper oxide starting material (CuO) is available as a 99 percent pure compound from Aldrich Chemical Company. Lithium hydroxide (LiOH) is available from a number of chemical outfits including Fluka and Aldrich.
