A battery includes an outer wall having a through-hole defined by a peripheral opening edge, at least one cell having a positive electrode and a negative electrode, an electrically conductive terminal stud connected to the positive electrode or the negative electrode, including a shaft extending through the through-hole, and at least one clamping element sitting on the shaft and covering the through-hole, and forming an annular gap together with the outer wall, an electrically insulating and annular support element surrounding the shaft of the terminal stud in a sleeve-like manner, and having an outward-facing peripheral contact surface against which the opening edge of the through-hole lies, wherein the support element includes a glass or a ceramic, or a glass- or ceramic-based composite material, and a sealing element arranged concentrically around the support element in the gap between the clamping element and the outer wall.

The invention relates to a pocket-type chain wheel () for link chains (), in particular round or profile steel chains. A circumferential surface () of said pocket-type chain wheel is provided with pockets () having alternately different shapes in the circumferential direction (U) and extending radially into the pocket-type chain wheel. In order to diminish noise generation in operation, reduce vibrations generated during operation and simultaneously cut production costs, the present invention discloses that the pocket-type chain wheel () is produced in one piece from a fiber-reinforced plastic by means of an injection molding process. Preferably, a main fiber direction () extends in a central area between the pockets () and a hub () in the radial direction.
