The behavior of Ni, NiO and LixNi1-xO in molten alkali carbonates is reviewed, analyzing step by step the process of lithiation, dissolution and sinterization at cell temperatures. The dissolution and the sintering processes of lithium nickel oxide in molten carbonates strongly depend on Li concentration in LixNi1-xO and on CO2partial pressure. The total amount of dissolved Ni species increases with x and PCO(2). Sintering process takes place in the presence of an appreciable amount of NiO2-or of Ni2+and O2-.
