The present invention provides conductive materials having high ionic conductivity and cationic transference number, small amount of polarization and good flexibility. The conductive material comprises high molecular compounds and alkalisiloxyaluminate.

Conductive materials and their compositions

A lithium sulfur secondary battery is provided with a cathode containing a highly basic polymer compound in a composition or in a form of a film. The lithium sulfur secondary battery gives a longer cyclic life of charging/discharging and high energy density.

Lithium sulfur secondary battery and elecrode material for a non-aqueous

An electrode material includes a sulfide compound containing an oxadiazole ring as an active substance. The secondary battery using such a material provides a large current at room temperature.

Electrode material and secondary battery

There is provided a disulfide type electrode material that can realize a remarkably improved energy density if used in a secondary battery as well as a secondary battery that shows a remarkably improved energy density. Such an organic electrode material comprises two or more than two but not more than six continuous S--S bonds.

Oligosulfide type electrode material and secondary battery containing

An absorbent solution for an absorption refrigeration apparatus is composed of water as a refrigerant and an absorbent. The absorbent is a mixture of at least three lithium compounds selected from the group consisting of lithium bromide, lithium iodide, lithium chloride, and lithium nitrate. The mixture ratio of, for example, lithium bromide to lithium iodide to lithium chloride in the absorbent is 1:0.1-1.0:0.05-0.50. Therefore, since absorption temperature sufficiently higher than crystallization temperature can be achieved, neither lithium halide nor lithium nitrate is precipitated in the absorbent solution during the operation cycle of the refrigeration apparatus.
