LiNi0.91Co0.09O2 and LiNi0.86Co0.09Mg0.05O2 phases were comparatively cycled in 4/5 ‘A’-size lithium-ion cells (500 cycles, 60°C, C rate, 2 h floating at 4.1 V at each charge). The MgCo substituted positive electrodes exhibit a very small cap

IEEE 35th International Power Sources Symposium.
The electrochemical properties of LiCoO/sub 2/ and LiNiO/sub 2/ materials in lithium rechargeable cells are presented and discussed. Cell data indicate that 165-Wh/kg D cells operating over 80 cycles can be constructed with both materials. These cell
