Nickel–metal hydride battery

A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery.The chemical reaction at the positive electrode is similar to that of the nickel-cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.NiMH batteries can have two to …

What is a Nickel-Cadmium Battery : Working & Its Applications

The working of the nickel-cadmium battery is based on the chemical reaction taking place between the layers. The battery which is a source of DC voltage consists of two ports i.e. anode and cathode. While making the battery, first the cadmium layer is kept on the redox. The cadmium layer acts as the cathode terminal.

The Beginner''s Guide to How a Battery Works

When the battery is charged, the chemical composition of the cathode is transformed and the nickel hydroxide changes to nickel oxyhydroxide [NiOOH]. In the anode, cadmium hydroxide is transformed to cadmium. As the battery is discharged, the process is reversed, as shown in the following formula. Cd + 2H2O + 2NiOOH —> 2Ni(OH)2 + …

Zinc–carbon battery

Old 3 V zinc–carbon battery (around 1960), with cardboard casing housing two cells in series. By 1876, the wet Leclanché cell was made with a compressed block of manganese dioxide. In 1886, Carl Gassner patented a "dry" version by using a casing made of zinc sheet metal as the anode and a paste of plaster of Paris (and later, graphite powder). …

Discharge and Charging of Lead-Acid Battery

When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte. The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation.. As a …

23.7: Batteries

This reaction regenerates the lead, lead (IV) oxide, and sulfuric acid needed for the battery to function properly. Theoretically, a lead storage battery should last forever. In practice, the recharge is not (100%) efficient, because some of the lead (II) sulfate falls from the electrodes and collects on the bottom of the cells.
