“…Both Sep/CNT/S and Sep/CNT/S@PANI composites show larger capacity at 2C rate, compared to our previous study of Sep/S composite with capacity of 750 mA h g À1 . 30 It is also obvious that the discharge capacity of Sep/CNT/S@PANI aer 300 cycles is much better than that of Sep/CNT/S. The discharge capacity of Sep/CNT/S only remains about 200 mA h g À1 aer 300 cycles, while corresponding capacity of Sep/CNT/S@PANI-I, III are about 400 mA h g À1 and Fig.…”

“…Indeed, the sepiolite-sulfur cathode delivered a high capacity at 0.2C rate, 63% of which was retained after 300 cycles. Under 1C current density, the first discharge capacity was still 84% of the initial value at0.2C, and the capacity fading was 0.1% per cycle over 500 cycles [294].…”

International audienceThis review is focused on the state-of-the-art of lithium-sulfur batteries. The great advantage of these energy storage devices in view of their theoretical specific capacity (2500 Wh kg−1, 2800 Wh L−1, assuming complete reaction to Li2S) has been the motivation for a huge amount of works. However, these batteries suffer of disadvantages that have restricted their applications such as high electrical resistance, capacity fading, self-discharge, mainly due to the so-called shuttle effect. Strategies have been developed with the recent modifications that have been proposed as a remedy to the shuttle effect, and the insulating nature of the polysulfides. All the elements of the battery are concerned and the solution, as we present herewith, is a combination of modification of the cathode, of the separator, of the electrolyte, including the choice of binder, even though few binder-free architectures have now been proposed

“…The sepiolite‐based composites show high performance in the field of photocatalysis, adsorption, coating, and ceramics. However, sepiolite has not received much attention in energy storage and conversion . Herein, TiO 2 /sepiolite composite for Li‐ and Na‐ion batteries is prepared by hydrothermal reaction and its electrochemical properties are assessed.…”

[37][38][39][40][41] Herein, TiO 2 /sepiolite composite for Li-and Na-ion batteries is prepared by hydrothermal reaction and its electrochemical properties are assessed. This work reports that both of the sepiolite and TiO 2 /sepiolite composites have the potential for the anode materials for Li-and Na-storage.…”

Natural sepiolite is widely used as an inorganic template to prepare functional nanomaterials. Herein, raw sepiolite and ultrafine TiO2 nanocrystals–decorated sepiolite nanofibers are fabricated by a hydrothermal reaction followed by an annealing process. For Li‐storage, the TiO2/sepiolite composites exhibit higher specific capacity and a longer lifespan than raw sepiolite. At a current density of 0.3 A g−1, the optimized TiO2/sepiolite composites deliver a discharge capacity of 1811 and 618 mAh g−1 at 1st and 300th cycle, respectively. In addition, the composites show a very stable specific capacity of 100 mAh g−1 at a current density of 0.1 A g−1 for Na‐storage up to 100 cycles.
