Abstract
The invention is a rare-earth-containing aluminum-air battery, where its aluminum alloy anode, air electrode and electrolyte all contain rare-earth elements, and because the rare-earth elements are activated, its service life is prolonged by 4-5 times as compared with the routine battery, and its cost is reduced by 50%.
Description
One. technical field
The present invention relates to field of chemical power source, particularly a kind of rare-earth containing aluminium air cell
Two background technologies
Aluminum-air cell normally is made up of aluminum metal anode, air electrode and electrolyte.The aluminum metal anode adopts Al-Ga-In-Sn more, Al-Ga-In-P, and etc. alloy aluminum, Ga wherein, In is an expensive metal; Catalyst in the air electrode is used precious metals ag more, and Pt, Co. cause the battery cost high.Battery life also cannot improve.Patent CN 1035408C has proposed improvement, and aluminum alloy anode still contains noble metal Ga.In, not the subject matter of workout cost and cycle life.As improve the utilance of aluminium alloy.Solve Al (OH) in the electrolyte
3Precipitation, thereby problems such as increase battery cycle life.
Three. summary of the invention
The objective of the invention is to propose a kind of rare-earth containing aluminium air cell
Purpose of the present invention can realize by following measure:
Rare-earth containing aluminium air cell comprises housing, aluminum metal anode, air electrode and electrolyte, aluminum metal anode in invention, adopt polynary aluminium tin rare-earth alloy material, its alloying component (quality) is: 0.01~0.15%Ca, 0.1~1.0%Sn, 0.01~0.5%Re, surplus Al; Air electrode is by catalyst layer, the stainless steel conducting matrix grain, and waterproof ventilative layer is formed.Wherein catalyst contains MnO
2And the mass ratio of ReO. between them is: MnO
2/ ReO=1/0.3~1.2; Electrolyte is 3~8mol/L NaOH+0.05~0.20mol/L Na
2SnO
3+ 0.01~0.5mol/L Re (OH)
3The rare earth element that adds is one or more combinations among La, Y, Pr, Nd, Gd, Tm, Er, Lu, the Sm.
Aluminum alloy anode in the battery of the present invention, air electrode all contains in the electrolyte and deposits rare earth element Re. and its advantage is that the activation of rare earth element makes aluminum alloy anode active high, and electric current is big, and cost is low, and catalyst contains rare earth it is active strong and lasting in the air electrode.Cost has only Ag, and 1/10 of Pt class catalyst contains Re (OH) in the electrolyte
3Can play the crystal seed effect and can make Al (OH)
3Rapid crystalline deposit.And make the life-span of this battery improve 3~5 times than existing aluminum-air cell.And price is low.
