摘要
Electrochemical characterisation of LiNi1-x-yCoxAlyO2 cathode material was conducted and a high reversible capacity of 184 mAh g(-1) was obtained with good capacity retention. Evaluation of LiNi1-x-yCoxAlyO2 performance with a graphitic carbon anode was undertaken in several alternative high energy density Li-ion cell configurations. These included a D-size (33,600) cell design, a flat, "soft-packaged" 10 Ah cell design and a high capacity 75 Ah metal case cell design. Energy densities of 160, 150 and 130 W h kg(-1) were achieved. respectively, for these cell designs. Further optimisation of these designs is envisaged to lead to projected energy densities, respectively, of 175, 180 and 150 W h kg(-1). (C) 2001 Elsevier Science B.V. All rights reserved.
