Characterization of Na _x Li_0.67+y Ni_0.33Mn_0.67O₂ as a positive electrode material for lithium-ion batteries.

ABSTRACT: The relationship between the charge-discharge properties and crystal structure of Na _x Li_0.67+y Ni_0.33Mn_0.67O₂ (0.010 ≤ x ≤ 0.013, 0.16 ≤ y ≤ 0.20) has been investigated. Li/Na _x Li_0.67+y Ni_0.33Mn_0.67O₂ cells exhibit gradually sloping initial charge and discharge voltage-capacity curves. The initial charge capacity increased from 171 mA h g^-1 for thermally-treated Na_0.15Li_0.51Ni_0.33Mn_0.67O₂ to 226 mA h g^-1 for Na_0.010Li_0.83Ni_0.33Mn_0.67O₂ with an increase in the Li content. The initial maximum discharge capacity
