A battery with a carbonaceous anode and a lithium manganese oxide spinel cathode. The carbonaceous anode is manufactured from graphite particles selected from the group consisting of: synthetic graphite particles, carbon-coated graphite particles, carbonized petroleum coke particles, carbon-coated coke particles and mixtures thereof. The lithium manganese oxide spinel cathode has a valence above 3.5. The production of the carbonaceous anode is obtained by: a) determining the initial coulombic efficiency and the specific capacity of the lithium manganese oxide spinel cathode in a cell against lithium metal; b) selecting a desired mixture of the graphite particles; c) comparing the initial coulombic efficiency of the graphite particles to that of the lithium manganese oxide spinel cathode; and d) selecting the appropriate amount and mixture of the graphite particles so that the initial coulombic efficiency of the carbonaceous anode is lower than that of the lithium manganese oxide spinel cathode. |
