CHEMICAL CELL ANODE AND METHOD OF MAKING SAID ANODE Russian patent published in 2013 - IPC H01M4/04 H01M4/46 

FIELD: chemistry.

SUBSTANCE: disclosed anode contains, wt %: magnesium 5-6, scandium 0.17-0.25, zirconium 0.05-0.12, beryllium 0.0001-0.005, copper 0.01-0.05, manganese 0.25-0.4, and inevitable impurities, including not more than 0.15 wt % iron and not more than 0.1 wt % silicon, having a structure which consists of grains of a solid solution having an elongated shape and thickness of 1-10 mcm, inclusions of aluminium-scandium-zirconium and aluminium-manganese-iron intermetallic phases and magnesium-silicon phases with size of 2-10 mcm and dispersed particles of the aluminium-scandium-zirconium phase with size of 2-10 nm. The disclosed method of making an anode of said composition involves melting an ingot of an alloy in form of a solid solution based on aluminium, with grain size and size of 30-90 mcm, with inclusion of intermetallic phases, homogenising annealing of the ingot, pressing the ingot into a strip, annealing the strip, straightening the strip by stretching and cutting an anode of given size.

EFFECT: use of the disclosed anode in an alkali-stannate electrolyte enables to reduce polarisation losses and increase maximum load current.
