The invention relates to a grid arrangement for a plate-shaped battery electrode of an electrochemical accumulator comprising a frame and a grid arranged thereon, wherein the frame comprises at least one upper frame element having a connecting lug of the battery electrode disposed on its side facing away from the grid, wherein the grid comprises grid bars respectively surrounding cutouts of the grid, wherein the majority of the grid bars surrounding the cutouts are respectively disposed in a hexagonal arrangement such that the cutout situated in between forms a hexagon, characterized by one, some or all of the following a), b), c), d), e) features):
a) the grid arrangement is coated with a pasty active mass on which liquid-absorbing material designed to absorb liquid electrolyte of the accumulator is disposed,b) the size of the hexagonal cutouts increases toward the upper frame element,c) the grid bars of all the hexagonal cutouts have the same width or the same cross-sectional area,d) none of the grid bars of the hexagonal cutouts run horizontal or parallel to the upper frame element,e) none of the grid bars of the hexagonal cutouts run vertical or perpendicular to the upper frame element.;The invention further relates to an accumulator. |

1. A grid arrangement (101, 102) for a plate-shaped battery electrode (104, 105) of an electrochemical accumulator (100), comprising a frame (117, 118, 119, 120) and a grid (113) arranged thereon, wherein the frame (117, 118, 119, 120) comprises at least one upper frame element (120) having a connecting lug (103) of the battery electrode (104, 105) disposed on its side facing away from the grid (113), wherein the grid (113) comprises grid bars (11 to 16) respectively surrounding cutouts (1, 2, 3) of the grid (113), wherein the majority of the grid bars (11 to 16) surrounding the cutouts (1, 2, 3) are respectively disposed in a hexagonal arrangement such that the cutout (1, 2, 3) situated in between forms a hexagon, characterized by one, some or all of the following a), b), c), d), e) features:
a) the grid arrangement (113) is coated with a pasty active mass (116) on which liquid-absorbing material (106) designed to absorb liquid electrolyte of the accumulator (100) is disposed, b) the size of the hexagonal cutouts (1, 2, 3) increases toward the upper frame element (120), c) the grid bars of all the hexagonal cutouts (1, 2, 3) have the same width (B) or the same cross-sectional area, d) none of the grid bars (11 to 16) of the hexagonal cutouts (1, 2, 3) run horizontal or parallel to the upper frame element (120), e) none of the grid bars (11 to 16) of the hexagonal cutouts (1, 2, 3) run vertical or perpendicular to the upper frame element (120). |
