The preferred embodiment provides a unique solid-state electrolytic battery featuring high reliability and an extremely durably service life. The battery is capable of generating a large amount of dischargeble current and can be satisfactorily charged and discharged using the activated hydrogen-stored alloy/materials. This unique solid-state electrolytic battery incorporates a cathode comprised of activated hydrogen-stored alloy storing metallic-hydrogenated hydrogen; a solid-state electrolyte comprised of hydrogen-ion conductive elements; and an anode containing an activated guest material, primarily hydrogen-ions.

A rechargeable electrochemical battery having a solid organic electrolyte and a thin film cathode and anode. In particular, the battery employs a proton-conducting organic polymer which is a mixture of a strong acid and a base polymer, a thin film anode containing a hydride alloy, and a thin film cathode containing a NiO.sub.x active material. The battery is rechargeable and capable of fast discharging and recharging. Further, the battery can be hermetically sealed in a case.
A battery, such as an alkaline battery, that can provide a high energy output at a high rate and that has a relatively high ratio of manganese dioxide to cathode volume is disclosed. The battery can provide high energy output at a high rate when the battery is intermittently subjected to a high energy load.
A cathode that includes manganese dioxide and relatively small particles of nonsynthetic, nonexpanded graphite is disclosed. The graphite particles can have an average particle size of less than 20 microns. The cathode can be used in an electrochemical cell, such as a battery.
