Abstract: The discharge capacity and the cycle lifetime of Li-Mn-O spinel oxide with different technology factors were analyzed by chemical pattern recognition method, and some criteria for improving material properties were obtained. The ratio of lithium to manganese was the primary influencing factor on discharge capacities and cycle lifetime for Li-Mn-O spinel oxide. Additive was the secondary influencing factor. Synthesis temperature and time
impacted the properties slightly.

Key words: Li-Mn-O spinel oxide, Discharge capacity, Cycle life time, Chemical pattern recognition
