Here are the 5 disadvantages of Cobalt as according to Lev:

1. Must have a safety separator cost $1/sq. ft in all cells.
2. Must have a plunger to cut the lead to stop over charge/discharge.
3. Must have a High-current Impedance circuit
4. Must have mechanical vent to vent gases.
5. Must have a metal casing because of the gas pressure.

Maganese based cells need none of these.
