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 d
esign, 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) wer
e achieved. respectively, for these cell designs. Further optimisation of t
hese designs is envisaged to lead to projected energy densities, respective
ly, of 175, 180 and 150 W h kg(-1). (C) 2001 Elsevier Science B.V. All righ
