Aluminum anode for aluminum–air battery–Part I: influence of aluminum purity Effect of iron-containing intermetallic particles on the corrosion behaviour of aluminium Solid-electrolyte interphases (SEI) in nonaqueous aluminum-ion batteries Performance of Al–0.5 Mg–0.02 Ga–0.1 Sn–0.5 Mn as anode for Al–air battery in NaCl solutions
The passivity of aluminum is detrimental to its performance as an anode in batteries. Soaking of native oxide-covered aluminum in a chloroaluminate deep eutectic solvent gradually activates the electrode surface, which is reflected in a continuously decreasing open circuit potential.
The present study builds on our previous efforts on the electrochemical study of pure aluminium, technical grade aluminium and some alloys namely, Al–In, Al–Sn, and Al–In–Sn as anodes for aluminium/air battery with sodium chloride electrolyte.
An Al metal, both native and with a very thin oxide film, was studied as an anode for Al-ion batteries. Studies were carried out in an acidic ionic liq. electrolyte, composed of AlCl3 in 1-ethyl-3-methylimidazolium chloride ([EMIm]Cl), with β-MnO2/C as a cathode.
(Royal Society of Chemistry) An aluminum-ion rechargeable battery comprised of an electrolyte contg. AlCl3 in the ionic liq., 1-ethyl-3-methylimidazolium chloride, and a V2O5 nano-wire cathode against an aluminum metal anode is reported.
Contrary to a Li-ion battery utilizing graphite as an anode, an Al chloride battery exploits the reversible oxidation of the graphite network, i.e., its cathodic functionality. The non-rocking-chair, i.e., mixed-ion, operation of the battery is clearly seen from Figure 1a. The following half-reactions take place upon charging: (I) (II)
