Battery chemistry may have improved battery performance. Iron, to alkaline, nickel-cadmium, nickel metal hydride to the various lithium variations. Weight and recharargability were the driving motives. However most of the improvements in live were centered around packing in more storage media or making high density batteries which often proved problematic
