The electrochemical performance of nickel foam, sintered nickel and nickel deposited on Reticulated Vitreous Carbon (RVCŽ) in KOH solutions has been investigated. The results indicate that the foam nickel is a very good carrier for redox couple Ni(OH)2/NiOOH which is used in alkaline rechargeable batteries as an electrode material. Also RVC covered with nickel is a good matrix for nickel hydroxide and it can be used as a positive electrode in secondary alkaline batteries. Foam nickel saturated with Ni(OH)2 has the best weight capacities in comparison to sintered nickel and nickel deposited on RVC. Sintered nickel saturated with Ni(OH)2 has the best volume capacity. However, Ni/RVC-NiOOH electrode has much better weight specific energy than that typical for sintered nickel saturated with NiOOH. The influence of additives (derivatives of cellulose) on sizes of pores and their distribution in sintered nickel and power capacity of positive electrode has been also studied.
