Li/graphite fluoride (GFx) cells, with highest theoretical capacity in primary lithium batteries, high energy density, long shelf life, safety and a wide operating temperature, have been widely noticed during the past decades. However, the low electronic conductivity and discharge potential of Li/GFx cells obviously limited its applications. The key to improve the energy performance of Li/GFx cells is to increase the transportation ability of Li+ in cathode materials. Considering its high specific surface area, large bulk volume and layer spacing, Ketjenblack is used for preparing the cathode materials with highly stored energy. Based on gas-solid fluorination, we synthesized the fluorinated Ketjenblack (FKB). As the cathode materials of lithium batteries, electrochemical assay show that the lithium/FKB cells have a novel discharged voltage of 3V versus Li/Li+ electrode, and a special capacity near 800 mAh g-1. The lithium/FKB cells may be used for a new highly stored energy device.

However, the low electronic conductivity and discharge potential Li/GFx cells obviously limited its applications.

Considering its high specific surface area and large layer spacing, bamboo charcoal is suitable for preparing the cathode materials with highly stored energy. Here, we synthesized the fluorinated bamboo charcoal (FBC) as the novel cathode materials based on gas-solid fluorination. Electrochemical assay show that the lithium/fluorinated bamboo charcoal cells have a novel discharged voltage of 3V versus Li/Li+ electrode, and a special capacity above 750 mAh g-1. The lithium/fluorinated bamboo charcoal cells may be used for new highly stored energy device in the future.

Li/graphite fluoride (GF) cells are well known to have high energy density, good reliability, long shelf life, safety and wide operating temperature. However, the low electronic conductivity and discharge potential of Li/GF cells obviously limited its applications. In order to improve the energy performance of Li/GF cells, an efficient method is to increase the transportation ability of Li+in cathode. The decreasing layers of graphite could increase the fluorinated surface between carbon and fluorinating agent, resulting in the emerge of the C-F bands of fluoride. Multi-walled carbon nanotube (MWCNT) can be considered as a curly materials of nature graphite sheets. This barrel structure shows much more C-F bands when they were fluorinated and turned into fluorinated MWCNT. And these emerged C-F bands are advantageous when they react with lithium ion during discharge. The results show that Li/FMWCNT cells possess higher discharge potential than Li/GF cells.

Lithium-ion hybrid capacitors (LICs) are regarded as one of the most promising next generation energy storage devices. Commercial activated carbon materials with low cost and excellent cycling stability are widely used as cathode materials for LICs, however, their low energy density remains a significant challenge for the practical applications of LICs. Herein, Na0.76V6O15 nanobelts (NaVO) were prepared and combined with commercial activated carbon YP50D to form hybrid cathode materials. Credit to the synergism of its capacitive effect and diffusion-controlled faradaic effect, NaVO/C hybrid cathode displays both superior cyclability and enhanced capacity. LICs were assembled with the as-prepared NaVO/C hybrid cathode and artificial graphite anode which was pre-lithiated. Furthermore, 10-NaVO/C//AG LIC delivers a high energy density of 118.9 Wh kg−1 at a power density of 220.6 W kg−1 and retains 43.7 Wh kg−1 even at a high power density of 21,793.0 W kg−1. The LIC can also maintain long-term cycling stability with capacitance retention of approximately 70% after 5000 cycles at 1 A g−1. Accordingly, hybrid cathodes composed of commercial activated carbon and a small amount of high energy battery-type materials are expected to be a candidate for low-cost advanced LICs with both high energy density and power density.
