Dry Cell

A dry cell is a type of electrochemical cell that was developed in the 19th century. A dry cell uses a chemical reaction between the electrodes and the electrolyte. These cells consist of low-moisture electrolytes in a paste form. A dry cell battery is a type of electric battery that is used in portable electronic […]

Zinc Carbon Battery

The technology behind zinc carbon batteries dates back to 1866 and the invention of a wet cell by Georges Leclanche. This makes it one of the oldest types of battery still in general use. The contemporary version is a single-use, non-rechargeable dry battery which delivers 1.5 volts per cell. How are they made? The structure […]

Frog Battery

This type of battery is exactly as its name suggests. It was developed in the 18th century as a method of storing usable energy based on the belief that electricity was generated solely by living creatures. An Italian physicist discovered that the muscles in the legs of dead frogs would twitch on the application of […]

Galvanic Cell

Galvanic Cell

A galvanic cell is a specific type of electrochemical cell that is commonly used to supply electric current. Named after the renowned scientists Luigi Galvani and Alessandro Voltais, it does this by transferring electrons via a redox reaction. A redox reaction is a type of chemical reaction that involves the transferring of electrons between two […]

Earth Battery

Earth Battery

Originally invented in 1841 by a scientist called Alexander Bain, the Earth Battery works by harnessing the electrical power of the earth to deliver an electrical charge. Alexander Bain was attempting to power telegraph lines when he discovered that burying a pair of electrodes made from different metals in damp ground or in water allowed […]

Aluminium Air

Aluminium Air

Aluminium air, or al-air, batteries are a major potential technology in the world of electric vehicles. Although they’re not currently routinely used in electric cars, this could change in the near future. Al-air batteries have a number of advantages over the lithium ion batteries which are generally used in electric cars. Aluminium is one of […]

Voltaic Pile

Voltaic Pile

The voltaic pile was invented by Italian chemist Alessandro Volta to provide a continuous electrical current to a circuit. It is widely hailed as the first battery invented and was widely used throughout the 19th century for industrial purposes until it was overtaken by the dynamo in the 1870s. The voltaic pile battery consisted of […]

Daniell Cell

Daniell Cell

The Daniell cell was invented by John Frederic Daniell in 1836. He was a British meteorologist and chemist who was looking to eliminate the voltaic pile’s hydrogen bubble issue and determined that zinc sulphate or sulphuric acid could be used to consume the hydrogen produced by the battery. His electrochemical cell consisted of an unglazed […]

Lithium Metal Battery

Lithium Metal Battery

Lithium metal batteries (sometimes also called ‘primary’ batteries) have metallic lithium as an anode, and are different to lithium-ion batteries, which contain both positive and negative electrodes. Lithium metal batteries are considered the optimum form of high specific energy batteries. Lithium metal batteries are usually non-rechargeable and can be found in a variety of applications, […]

Zinc Air Battery

Zinc Air Battery

A silver oxide battery is a primary cell with high energy density. Typically available as button cells, these types of batteries are primarily used in small appliances. A silver oxide battery has a silver cathode and a zinc anode. Energy is created through zinc oxidation with the silver oxide. What are silver oxide batteries used […]
