Potassium, an alkali metal similar to lithium (and sodium) can be used in a rechargeable battery. In a 2004 paper published in the Journal of Power Sources , Ali Eftekhari noted that “ the potential of the potassium anode and lithium anode are approximately the same with only a 0.12V difference. For comparison, they built a Li?O

Iron–air batteries, originally proposed in the 1970s, have theoretical energy densities of more than 1,200 Wh/kg; by comparison, present-day lithium-ion batteries come in at about 600 Wh/kg, and even less (350 Wh/kg) if the weight of the cell casing is taken into account. The deposits do not decrease the power of the battery.
