| A rechargeable transition metal battery includes a negative electrode, a positive electrode and an electrolyte.  The negative electrode includes a negative electrode material which is a transition metal or an alloy of the transition metal.  The positive electrode is electrically connected to the negative electrode and includes a host material and a positive electrode material.  The host material includes a carbon.  The positive electrode material is connected to the host material, and the positive electrode material is a compound of a metal, an elemental chalcogen or an elemental halogen.  The electrolyte is disposed between the positive electrode and the negative electrode. |
