ABSTRACTSubmicron carbon filaments used in place of carbon black as porous reduction electrodes in carbon limited lithium batteries in plate and jellyroll configurations with the BCX (bromine chloride in thionyl chloride) catholyte gave a specific capacity (at 2 V cut-off) of up to 8700 mAh/g carbon, compared to a value of up to 2900 mAh/g carbon for carbon black. The high specific capacity per g carbon (demonstrating superior carbon efficiency) for the filament electrode is partly due to the filaments' processability into sheets as thin as 0.2 mm with good porosity and without a binder, and partly due to the high catholyte absorptivity and high rate of catholyte absorption of the filament electrode.

Lithium rechargeable battery is a new type of battery developed in recent years. The studies on this system are naturally focused on the cathode material. The cathode material with conducting skeleton and energy-storing side lines was reported and a novel material carbyne polysulfide was studied. This paper was to explore a convenient approach for preparing carbyne polysulfide. The products obtained by co-heating polyvinylidene chloride(PVDC) and pulverized sulfur in ammonia environment was characterized by DSC /TG, IR, Raman spectrums and elemental analysis. And the product had been proved to have a sp2 hybride carbon skeleton with polysulfide attached on it, which resembles the theoretical structure of carbyne polysulfide. The material with favorable sulfur contents exhibited high specific capacity up to 705 mAh/g in the initial cycle and a stable reversible capacity approximately 420 mAh/g.
