Application: in electric equipment as a secondary current source (storage battery). Nature of the invention: Solid-state secondary current source, consisting from an anode (An0), in a form of a metal or an alloy of metals, whose fluorination leads to generation of fluoride or fluorides with high isobar generation potential, an electrolyte in a form of solid-state fluorine-ionic conductor with high ionic conductivity and low electronic conductivity and a cathode (KtF0) in a form of fluoride or solid solution of fluorides with low isobar generation potential, with cathodic reaction during discharge KtF0+e−→F−+Kt′ and anodic during discharge An0+F−→An′F+e−, in which anode and cathode are reversible with respect to fluorine-ions with cathode reaction during charge-discharge: KtFx0+Xe−XF−+Kt′ and anodic during charge-discharge An0+XF−An′Fx+Xe− at voltages that are below voltages of solid electrolyte decomposition, and anode, electrolyte and cathode contain in their composition at least one component that prevents destruction of solid-state battery during charge-discharge cycles. Technical result: the composition of secondary solid-state current source allows achieving high specific energy characteristics of secondary batteries with high number of charge / discharge cycles, ensuring safety of their utilization and lengthy retention of electric energy.
