Nanomat Li–S batteries based on all-fibrous cathode/separator assemblies and reinforced Li metal anodes: towards ultrahigh energy density and flexibility

Abstract

Nanomat Li–S batteries based on all-fibrous cathode/separator assemblies and reinforced Li metal anodes are presented to enable ultrahigh-energy-density and flexibility.

Cellulose Nanofiber/Carbon Nanotube‐Based Bicontinuous Ion/Electron Conduction Networks for High‐Performance Aqueous Zn‐Ion Batteries

“…The HNS electrode was fabricated by a simple vacuum‐assisted filtration method analogous to a traditional paper‐making method. [ 23 ] First, we synthesized rod‐shaped α‐MnO 2 particles using a hydrothermal method. [ 8 ] The crystalline structure and morphology of the synthesized MnO 2 particles are shown in Figures S1 and S2 in the Supporting Information.…”

Advanced Matrixes for Binder‐Free Nanostructured Electrodes in Lithium‐Ion Batteries

“…As the energy crisis and environmental pollution are becoming increasingly problematic, renewable energy technologies and effective energy storage systems have been rapidly developed to alleviate these challenges. Rechargeable batteries, including fuel cells, [ 1 ] lithium–sulfur batteries (Li–S), [ 2–4 ] silicon–sulfur batteries (Si–S), [ 5 ] lithium–oxygen batteries (Li–O 2 ), [ 6–8 ] sodium‐ion batteries (SIBs), [ 9–11 ] and lithium‐ion batteries (LIBs), [ 9,11–13 ] have proven to be one of the most high‐efficiency electrochemical energy storage systems. Among all the rechargeable batteries, next‐generation advanced batteries (e.g., fuel cell, Li–S, Si–S, Li–O 2 , and SIBs) are still being investigated in their embryonic stages due to the impeding factors of high cost, complex chemical reaction mechanisms, poor rate capability and cycling stability, as well as unreliable safety.…”

[ 2–13 ] In contrast, LIBs have been commercialized since 1991 and have attracted tremendous attention due to their appealing performance. Nowadays, LIBs are widely used as power sources in diverse fields ranging from personal portable electronics (e.g., mobile phones, laptops, and electronic watches) to pure‐electric vehicles, robombs, artificial satellites, and smart grids.…”

N‐Doped graphene embellished with Co 9 S 8 enable advanced sulfur cathode for high‐performance lithium‐sulfur batteries

“…Lithium-sulfur (Li-S) batteries are regarded a sort of most advanced energy storage technologies because of their satisfactory theoretical energy density (2.6 kW h kg −1 ) as well as inexpensive and nontoxicity of its sulfur element. [1][2][3][4][5] However, the industrialized process of Li-S batteries was impeded by certain factors, namely, (a) the dielectric nature of the active materials (S or Li 2 S 2 /Li 2 S), which leads to a low electrochemical performance in Sbased cathode [6][7][8] ; (b) the volume of the cathode material notably changes during its discharge/charge process, resulting in the cathode destruction 9,10 ; (c) a notorious shuttle effect arises from the intermediate lithium polysulfides (LiPS) diffusion, 11,12 leading to the quick capacity fading of cell. Consequently, these issues gave rise to poor capacity and short cycle life.…”
