Additionally, there are several magnesium batteries that are experimental, or in various stages of development iii) Magnesium-air batteries are also aqueous, primary batteries, but these use oxygen from the air for reduction at the cathode. Although much effort has been devoted for their development, up to date they have not been commercialized, iv) Magnesium-organic solvent...

Magnesium and aluminum are attractive candidates for use as anode materials in primary batteries. As shown in Table 1.1, Chap. 1, they have a high standard potential. Their low atomic weight and multivalence change result in a high electrochemical equivalence on both a gravimetric and a volumetric basis. Further, they are both abundant and relatively inexpensive.

The shelf life of the magnesium/manganese dioxide primary battery at various storage temperatures is compared with the shelf life of the zinc-carbon battery in Fig. 9.11. The magnesium battery is noted for its excellent shelf life. The battery can be stored for periods of 5 years or longer at 20°C with a total capacity loss of 10 to 20% and at temperatures as...

Magnesium primary batteries have been developed in other structures and with other cathode materials, but these designs have not achieved commercial success. Flat cells, using a plastic-film envelope, were designed but were never produced commercially.

Within each Part, chapters are included on all available types of primary batteries, secondary batteries and batteries available in primary and secondary versions. The primary batteries include carbon-zinc, carbon-zinc chloride, mercury-zinc and other mercury types, manganese dioxide-magnesium perchlorate, magnesium organic, lithium types (sulphur dioxide, thionyl chloride, vanadium pentoxide, iodine and numerous other lithium types), thermally activated and seawater batteries. Batteries available in primary and secondary Corms include alkaline manganese, silver-zinc, silver-cadmium, zinc-air and cadmium-air. The secondary batteries discussed include lead-acid, the nickel types (cadmium, iron, zinc, hydrogen), zinc-chlorine, sodium-sulphur and other fast ion types.
