He ical eNergy Storage1 A. Physical principlesA Nickel-Metal Hydride (NiMH) battery system is an energy storage system based on electrochemical charge/discharge reactions that occur between a positive electrode (cathode) that contains nickel oxyde-hydroxide as the active material and a negative electrode (anode) that is composed of a hy
Nickel hydroxide-based devices, such as nickel hydroxide hybrid supercapacitors (Ni-HSCs) and nickel-metal hydride (Ni-MH) batteries, are important technologies in the electrochemical energy storage field due to their high energy density, long cycle life, and environmentally-friendliness.
Their basic structure is identical to that of Ni-Cd batteries. With cylindrical nickel-metal hydride batteries, the positive and negative plates are seperated by the separator, wound into a coil, inserted into the case, and sealed by the sealing plate through an electrically insulated gasket. batteries.
Activated carbon (AC) and metal alloy storage materials are applied as anodes for Ni-HSCs and Ni-MH batteries, respectively. Alloys in Ni-MH batteries absorb hydrogen to form metal hydrides (MH) during the charging process and they release hydrogen, providing electrons for the electrochemical reactions during the discharge process.
