Abstract: Disclosed herein is a battery design for bi-cell polymer matrix batteries. Each bi-cell comprises, sequentially, a first counter electrode, a first separator membrane, a centrally located electrode, a second separator membrane, and a second counter electrode. The current collector of each of the counter electrodes is positioned other than medially within the counter electrode. Generally, the current collector of the counter electrode is located within the outer half of the counter electrode. When the current collector is located at the extreme outer edge of the counter electrode, a capping film of polymer matrix material is preferably laminated to the perforated current collector, and, through the perforated current collector, to the counter electrode material itself.

Abstract: A holder for detachably mounting a receptacle, such as a paint can, to a ladder has a generally L-shaped body having a foot portion and a back portion. The back portion is connected to a U-shaped curved portion and extension portion which form a hook for attaching the holder to a first rung of the ladder. The foot portion is connected to a front portion and rests on a second rung beneath the first rung of the ladder. A pivotable restraint member is attached to the back portion. This restraint member encloses the receptacle when it is resting on the foot portion in order to hold the receptacle on the holder. This holder can easily and quickly be mounted to the ladder. A top opening in the receptacle is easily accessed when using the holder. The restraint member is pivotable so that the holder can fold flat for transport and storage.
