Abstract
A modularized metal-air battery includes a metal-plate module, a first air-plate module and a second air-plate module. The metal-plate module has a metal anode enclosed in a frame that is thicker than the metal anode. Each of the first and second air-plate modules has an air cathode enclosed in a frame that is thicker than the air cathode. The first air-plate module, the metal-plate module and the second air-plate module are combined to constitute the metal-air battery in such a manner that the frames thereof are securely attached together thereby defining at least two chambers which are selectively filled with liquid electrolyte.
Claims20
A modularized metal-air battery comprising:
- at least one metal-plate module (11) having a metal anode (111) enclosed in a frame (112), the frame (112) of said at least one metal-plate module (111) having a thickness larger than said metal anode (111);
- a first and a second air-plate module (12, 13), each having an air cathode (121, 131) enclosed in a frame (122, 132), the frame (122, 132) of each air-plate module (12, 13) having a thickness larger than said air cathode (121, 131);
- said first air-plate module (12), said at least one metal-plate module (11) and said second air-plate module (13) being combined to constitute said metal-air battery in such a manner that said frames (122, 112, 132) thereof are securely attached together thereby defining at least two chambers (71);
- and liquid electrolyte selectively filled in said at least two chambers (71).
A method for manufacturing a modularized metal-air battery, comprising:
- a process for producing an air-plate module having the steps of:
- (a) providing a piece of film (1331) from a roll of film (133);
- (b) punching an aperture (1332) into said piece of film (1331);
- (c) providing a piece of metal screen (1341) by separating it from a roll of metal screen (134);
- (d) attaching said piece of metal screen (1341) to said piece of film (1331) such that said aperture (1332) is covered by said piece of metal screen (1341);
- (e) coating air cathode material (135) on said piece of metal screen (1341) attached to said piece of film (1331);
- (f) providing a piece of separator (1361) by separating it from a roll of separator (136);
- (g) attaching said piece of separator (1361) to said piece of metal screen (1341);
- (h) separating said piece of film (1331) from said roll of film (133);
- and
- (i) attaching a frame (137) to said piece of film (1331);
- and
- a process for producing a metal-plate module having the steps of:
- (a) providing a piece of metal screen (1441) from a roll of metal screen (144);
- (b) plastering metal powder (145) onto said piece of metal screen (1441);
- (c) pressing said metal powder (145) on said piece of metal screen (1441) to form a metal plate (146);
- (d) separating said piece of metal screen (1441) from said roll of metal screen (144);
- and
- (e) attaching a frame (147) to said piece of metal screen.
