“…Changhong also produce pocket plate and sintered plate NiCd. Sintered plate electrodes tend to have improved discharge rate characteristics compared to other types of Ni electrode due to the short distance electrons have to travel to the current collector since NiOOH has a fairly low conductivity (17). There is a play off between the amount of active material and reduction in conductivity.…”

Utility scale electrochemical energy storage will become an important topic as countries across the globe set targets for electricity generation from renewable sources. Much current research is focused on improving energy density for portable electronic devices or electric vehicles. In distributed photovoltaic generation applications energy storage is required due to the intermittent nature of the electricity supplied. In these situations space and weight is at less of a premium so lifetime and safety should be the driving factors of development. Currently nickel based battery technologies offer long cycle lives. There are a number of cathode configurations available, from the earliest pocket plate designs to sintered plates and fiber plates. In this work these electrodes have been evaluated for use in nickel based battery chemistries with a particular emphasis on manufacturability. Sintered electrodes can be produced on a roll to roll production line which is an attractive way of cutting manufacturing costs at the scale required for large scale domestic electricity storage. Sintered plates can also improve fast rate discharge characteristics and energy density.

“…Ni plaques are current collectors of choice for battery applications demanding high power and reliability, along with long cycle life, such as batteries for aerospace and railway applications, power tools, and portable electronics. Significant advances in the development of Ni plaques were achieved by the use of filamentary Ni particles with high surface area, which provided improved contact with active material [3,4]. The pore size of Ni plaques is usually much smaller compared to that of other industrial current collectors, such as Ni foams.…”

“…The pore size of Ni plaques is usually much smaller compared to that of other industrial current collectors, such as Ni foams. The smaller pore size decreased the distance for electrons to travel from the current collector into the active material during cell discharge and, consequently, improved the discharge rate characteristics [3,4]. Ni hydroxide is used as a positive electrode material for a number of alkaline secondary cells such as Ni/Cd, Ni/Fe, Ni/Zn, and Ni/MH cells [5].…”

Manganese dioxide nanofibers with length ranged from 0.1 to 1 lm and a diameter of about 4-6 nm were prepared by a chemical precipitation method. Composite electrodes for electrochemical supercapacitors were fabricated by impregnation of the manganese dioxide nanofibers and multiwalled carbon nanotubes (MWCNT) into porous Ni plaque current collectors. Obtained composite electrodes, containing 85% of manganese dioxide and 15 mass% of MWCNT, as a conductive additive, with total mass loading of 7-15 mg cm -2 , showed a capacitive behavior in 0.5-M Na 2 SO 4 solutions. The decrease in stirring time during precipitation of the nanofibers resulted in reduced agglomeration and higher specific capacitance (SC). The highest SC of 185 F g -1 was obtained at a scan rate of 2 mV s -1 for mass loading of 7 mg cm -2 . The SC decreased with increasing scan rate and increasing electrode mass.
