A. Brief Introduction of NiMH batteries
Rechargeable Ni-MH batteries are comprised of a positive electrode plate which uses nickel hydroxide as its main active material, a negative electrode plate which uses hydrogen-absorbing alloys as its main active material, a separator made of a thin non-woven fabric, an alkaline electrolyte, a metal case, a sealing plate provided with a self-sealing safety valve, and other components. The positive and negative electrode plates, isolated from each other by the separator, and rolled in a spiral shape inside the case and sealed by the sealing.
