Inner pressure characterization of a sealed nickel-metal hydride cell

▶ We study the inner pressure of gases inside a sealed Ni-MH cell. ▶ The inner cell at continuous use does not increase for Ic up to 0.5 C. ▶ Overcharges at high rates significantly increase the inner cell pressure. ▶ Efficient fast charge by charging the cell up to 90% of nominal capacity. ▶ The cut-off discharge criterion at high rates for the complete discharge of battery.
