Magnesium Anode

Magnesium electrode is a kind of electrochemical energy technology utilizing magnesium or magnesium alloy as the active material, which includes various forms, such as magnesium alloy sacrificial anode, magnesium battery, magnesium ion electrode, and magnesium seawater fuel cell. Each of these forms has its own characteristics and application areas, which will be introduced separately below.

Magnesium alloy sacrificial anode: mainly used in the field of corrosion control and cathodic protection. They are characterized by high driving voltage and low current efficiency and are suitable for soil or freshwater environments. The current efficiency of magnesium anode is about 50%, which may be lower by the environment, so it is used under specific conditions.

Magnesium batteries: These include Mg/AgCl batteries, etc., which have a life span of 5 to 10 years, making them a relatively long-life battery system.

Magnesium Ion Electrode: This is a new electrochemical energy technology that uses magnesium ions as the positive electrode material of the battery, and generates electricity through the participation of magnesium ions in the electrolyte in an electrochemical reaction. Compared with traditional lithium batteries, magnesium ion electrode has the advantages of high energy density, long cycle life, safety and stability.

Magnesium Seawater Fuel Cell: This is a device that utilizes oxygen dissolved in seawater as an oxidant to convert the chemical energy of magnesium metal into electrical energy. It usually adopts an open structure design, with magnesium or magnesium alloy for the anode and different materials for the cathode according to different battery types.

Each of these forms of magnesium electrode technology has its own unique application scenarios and advantages, ranging from corrosion control to portable power sources to energy sources for deep-sea exploration, demonstrating the diversity and potential of magnesium electrode technology.
