Lab Improves Li-Ion Batteries by 30 Percent

PC Magazine reports: "A couple of problems faced by the widely-used lithium-ion batteries are the risk of overcharging and the subsequent degradation of charging capability. Research for the improvement of lithium-ion has reached a milestone in Argonne National Laboratory where longer battery life and a 30 percent increase in storage capacity have been achieved. To be able to prevent overheating and combustion, researchers replace cobalt oxide electrodes (which easily overheat) with manganese oxide--a more stable material."

The problem with battery technologies is that advances in this area are painfully slow.
