Embodiment Construction

[0076] according to figure 1 and figure 2 A metal-air cell 1 , preferably comprising an aluminum-air cell, comprises a housing 2 that is electrically insulating and preferably consists of an electrically insulating material such as plastic. In the example shown, the housing 2 is designed as a cylindrical container and has a cylindrical jacket 3 and a plate-shaped, in particular circular, base 4 . In the installed state or ready-for-use state of the metal-air battery 1 , which can subsequently also be denoted abbreviatedly as battery 1 , the casing 2 is arranged so that the longitudinal center axes 5 of the casing 2 are substantially vertically aligned, ie substantially parallel Yu Zai figure 1 The direction of gravity 6 indicated by the arrow in . The battery 1 also comprises at least one hollow cylindrical cathode 7 which is arranged in the casing 2 and which is particularly preferably so that the longitudinal central axis 8 of the cathode 7 is substantially parallel to t...

Abstract

The invention relates to a metal-air battery (1), comprising a housing (2), a cathode (7), which is arranged between an air space (9) and an electrolyte space (10) in the housing (2), a metal anode (11), which is arranged in the electrolyte space (10), an air path (14) leading through the housing (2), which air path leads from an air inlet (15) of the housing (2) to an air outlet (16) of the housing (2), an air supply device (20) for producing an air flow, which follows the air path (14) and impinges on the cathode (7), an electrolyte path (17) leading through the housing (2), which electrolyte path leads from an electrolyte inlet (18) of the housing (2), which electrolyte inlet is fluidically connected to the electrolyte space (10), to an electrolyte outlet (19) of the housing (2), which electrolyte outlet is fluidically connected to the electrolyte space (10), and an electrolyte supply device (21) for producing an electrolyte flow, which follows the electrolyte path (17) and impinges on the anode (11) and the cathode (7).

Description

technical field [0001] The present invention relates to metal-air batteries, in particular to aluminum-air batteries. The invention also relates to a battery system comprising at least two such batteries. The invention furthermore relates to an electric vehicle equipped with at least one such battery or at least one such battery system. Finally, the invention relates to a method of operating such a battery. Background technique [0002] Metal-gas batteries are generally primary batteries, ie non-rechargeable galvanic cells, which develop a specific voltage due to the chemical reaction of the corresponding metal with air oxidation. Such primary cells can also be designated as fuel cells. Unlike the primary battery, the secondary battery is a so-called rechargeable battery capable of charging. [0003] An exemplary structure for a zinc-air battery is known from WO 2012 / 156972 A1. [0004] Zinc electrodes for use in rechargeable batteries are known from WO 2013 / 150519 A1. ...
