A secondary battery having high electromotive force and including less lead or being free of lead is provided. The secondary battery includes a positive electrode including a positive electrode active material containing manganese oxide, a negative electrode including a negative electrode active material containing at least one selected from zinc, gallium, and tin, and an electrolytic solution containing at least one selected from phosphoric acid and organic oxoacid and having a pH of less than 7 at 25° C. This secondary battery has an open circuit voltage of more than 1.6 V in a fully charged state.

A process for recovering a nickel cobalt manganese hydroxide from recycled lithium-ion battery (LIB) material such as black mass, black powder, filter cake, or the like. The recycled LIB material is mixed with water and either sulfuric acid or hydrochloric acid at a pH less than 2. Cobalt, nickel, and manganese oxides from the recycled lithium-ion battery material dissolve into the acidic water with the reductive assistance of gaseous sulfur dioxide. Anode carbon is filtered from the acidic water, leaving the dissolved cobalt, nickel, and manganese oxides in a filtrate. The filtrate is mixed with aqueous sodium hydroxide at a pH greater than 8. Nickel cobalt manganese hydroxide precipitates from the filtrate. The nickel cobalt manganese hydroxide is filtered from the filtrate and dried. The filtrate may be treated ammonium fluoride or ammonium bifluoride to precipitate lithium fluoride from the filtrate. The composition ratio of nickel to cobalt to manganese in the acid filtrate may be adjusted to a desired ratio. The anode carbon is recovered and purified for reuse.

A primary battery includes a cathode having a non-stoichiometric metal oxide including transition metals Ni, Mn, Co, or a combination of metal atoms, an alkali metal, and hydrogen; an anode; a separator between the cathode and the anode; and an alkaline electrolyte.
