While the performance Of beta(bc) (bc: badly crystalline)-nickel hydroxide is relatively unaffected by the use of different lightweight supports., the specific discharge capacity of crystalline beta-Ni(OH)(2) doubles to approximately 355 mAh g(-1) Ni (theoretical, 456 mAh g(-1)) when pasted to a fibre support compared with 170 mAh g(-1) Ni when pasted to a nickel foam. Consequently, the fibre is a superior support as it is unaffected by the quality of the active material and extracts a consistently high performance irrespective of the degree of crystallinity, moisture content, morphology and composition of the active material. Electrochemical impedance measurements indicate that a lower charge-transfer resistance at low states-of-charge is responsible for the superior performance of fibre supported beta-Ni(OH)2 electrodes.
