The battery cells may include a separator positioned between the anode and the cathode. The battery cells may include an electrolyte incorporated with the anode and the cathode. The battery cells may also include a pseudo-reference electrode at least partially in contact with the electrolyte.

Batteries are described that include a cathode material, and anode material, and a polymeric material that separates the cathode material from the anode material. The polymeric material has hydroxide ion conductivity of at least about 50 mS/cm, and a diffusion ration of hydroxide ions to at least one type of metal ion of at least about 10:1. Also described are methods of making a battery that include forming a layer of polymeric material between a first electrode and second electrode of the battery. In additional methods, the polymeric material is coated on at least one of the electrodes of the battery. In further methods, the polymeric material is admixed with at least one of the electrode materials to make a composite electrode material that is incorporated into the electrode.

Insulators and polymer-coated insulators are provided. The insulators can include thermally-insulating nanoparticles and a binder configured to volatilize at a volatilization temperature. Insulators can also include an inorganic thermally-insulating material forming a porous structure. The porous structure can be configured to reduce the mean free path of gases in the insulator as compared to gases outside the porous structure. Polymer-coated insulators including an inorganic thermally-insulating material and a polymer coating disposed on the surface of the inorganic thermally-insulating material are also provided. Insulators can also include thermally-insulating nanoparticles and an opacifier. The opacifier can include a carbonaceous material coated with a refractory material that inhibits oxidation of the carbonaceous material at a carbon oxidation temperature. The insulators or polymer-coated insulators can be disposed between battery cells or battery cell blocks in an apparatus.

An educational game is provided and includes a transparent sleeve having a plurality of elongated compartments in which movable opaque slides are positioned. A set of transparencies are also provided and on each transparency there is a column of legends that are spaced so as to be in juxtaposition with a grip formed on at least one surface of the transparent sleeve. Thus, each of the legends, which may be in the form of questions or statements, are in alignment with one of the squares in the transparency grid. A projector is positioned so that the legends on the transparencies may be projected onto a surface such as a wall. As the opaque slides are withdrawn successive legends will be projected. The legends may be answered as part of a teaching technique or a game may be played with a plurality of individuals or teams with the time being a factor for answering the questions or identifying the legends. As the slides are pulled out further the questions or statements become progressively more difficult.
