Vz. Barsukov et al., POROUS-ELECTRODES AND PROTOTYPES OF SECONDARY CELLS BASED ON A NOVEL ELECTROCHEMICAL SYSTEM GRAPHITE-HBF4-ANTHRAQUINONE, Russian journal of electrochemistry, 31(4), 1995, pp. 398-402
Porous electrodes and experimental prototypes of rechargeable batterie
s based on a novel electrochemical system graphite-HBF4 + tetrafluorob
orate additives-anthraquinone are developed. Intercalation of anions i
n the graphite electrode is studied in detail and the intercalation po
tential is determined (E(i) similar to 1.55 V vs. Ag-AgCl). Side react
ions proceeding concurrently with primary current-generating processes
at the electrodes are described. Feasibility of hermetically sealing
a battery based on the new system due to anthrahydroquinone's ability
to reduce oxygen that evolves during charging is demonstrated.
