Description

Technical Field

[0002] Nickel-metal hydride battery is a widely used rechargeable battery, with nickel hydroxide as the positive electrode and metal hydride as the negative electrode. Compared with traditional nickel-cadmium batteries, nickel-metal hydride batteries have higher energy density, lower self-discharge rate and more environmentally friendly advantages, so they have been widely used in many fields. The working principle of nickel-metal hydride batteries is based on the redox reaction of hydrogen ions. During the charging process, hydrogen ions move from the metal hydride at the negative electrode to the nickel hydroxide at the positive electrode, and electrons also flow from the negative electrode to the positive electrode through the external circuit to form a current. During the discharge process, hydrogen ions and electrons move in opposite directions, flowing from the positive electrode back to the negative electrode, thereby releasing electrical energy. The advantages of nickel-metal hydride batteries are their high energy density, low self-discharge rate, and environmentally friendly.
