Study of Three-Component System Al, Na, Li/Cl for Sodium Nickel-Chloride Batteries

The electrical conductivity, thermochemical and electrochemical properties of a system consisting melts aluminium trichloride sodium-lithium chlorides taken in different ratios have been studied. In this system, the behaviour Ni2+ ions via cyclic voltammetry electromotive force modes heating cooling were It was found that melting temperature passes through minimum at lithium chloride (хLiCl) content from 0.23 to 0.35. A possibility reducing starting nickel-chloride battery with partial replacement sodium is shown, as well stabilization its operation 240 °C. An admissibility using optimal compositions an electrolyte batteries has established. composition 0.5AlCl3-0.23LiCl-0.27NaCl point (111 °C), activation energy for conductivity (8.9 kJ∙mol-1), sufficiently high (0.53 S∙cm-1 250 °C).
