Magnesium reserve cells

The last type of reserve cell is the thermally activated cell, lhe older designs use calcium or magnesium anodes newer types use lithium alloys as anodes. 

In previous sections of this chapter, magnesium anodes have been considered as replacements for zinc in Leclanche and air-depolarized cells. In sea water-activated reserve batteries, magnesium anodes are coupled with either silver chloride, lead chloride, manganese dioxide or, occasionally,... 

Numerous microorganisms synthesize PHAs by the fermentation of a carbon source and then accumulate them as intracellular carbon reserve inclusion bodies. In order to accumulate PHAs, in most bacteria an excess supply of carbon and limitation of nitrogen, phosphorus, oxygen or magnesium is required. These unfavourable growth conditions result in a decrease in cell growth and division, and a... 

Magnesium/Manganese Dioxide Battery. This reserve battery consists of a magnesium anode and a manganese dioxide cathode. - It is activated by pouring an aqueous magnesium perchlorate electrolyte into the cells of the battery, where it is absorbed by the separators. Electrolyte absorption occurs within a few seconds at 0°C or above, but 3 min or more are required at -40°C due to the viscosity of the electrolyte.
