7 Investigations of Bulk Li–Mn–Ni–O Samples to Confirm the Combinatorial Studies
Fig. 7.6 Electrochemical data of half cells made from the M, N and R materials obtained by heating
in oxygen at 800
◦ C and quenching to room temperature. The cells were first cycled between 2.5–
4.6 V for two cycles (shown in all panels, with the first cycle shown as a thick red line in the dQ/dV
plots), then between 2–5 V for ten cycles (for clarity, only a few of these are included in the voltage
versus capacity plots). All measurements were performed at a constant specific current of 10 mA/g
such that the M-layered material was cycled at a rate of approximately C/24 (i.e., 24 h to charge or
discharge)
