Found this awesome snippet of information:

Chemistry  Cobalt                                    Manganese (Spinel) Energy     140 Wh/kg                                 120 Wh/kg Safety     On overcharge, the cobalt electrode       On overcharge, the manganese electrode            provides extra lithium, which can         runs out of lithium causing the cell            form into metallic lithium, causing       only to get warm. Safety circuits can            a potential safety risk if not            be eliminated for small 1 and 2 cell            protected by a safety circuit.            packs. Temper.    Wide temperature range. Best suited       Capacity loss above +40°C. Not as            for operation at elevated temperature.    durable at higher temperatures. Aging      Short-term storage possible.              Slightly less than cobalt.

Due to continuous improvements,                                                      storage time is difficult to predict.

Cost       Raw material relatively high;             Raw material 30% lower than cobalt.            protection circuit adds to costs.         Cheaper, simpler protection circuit.
