N-Doped Carbon Nanofibers Encapsulating CoO@Co9S8 Nanoparticles: Preparation from S-Rich Co32 Coordination Cluster Precursors by Electrospinning and Application for Superior Li-ion Storage

Advanced Carbons Nanofibers‐Based Electrodes for Flexible Energy Storage Devices

“…0D structural materials including nanoparticles and quantum dots can be uniformly decorated on or embedded in the CNFs, which can not only increase the number of active sites, but also provide excellent structural stability. In recent years, various types of active materials nanoparticles composited with CNFs have been adopted for flexible LIBs such as metal (Ge, Si [ 65 ] and Sn), metal oxides (Fe 2 O 3 , [ 48 ] Fe 3 O 4 , [ 66 ] SnO 2 , CoO, [ 67 ] Co 3 O 4 , ZnO, etc. ), metal fluorides, [ 68 ] and so on.…”

Achieving a high loading of cathode in PVDF-based solid-state battery

“…Solid-state lithium metal batteries (SSLMBs) with a lithium (Li) metal anode and high-voltage cathodes (i.e., LiNi 0.8 Co 0.1 Mn 0.1 O 2 , NCM811) are considered to be a promising combination to improve both the safety and energy density of secondary batteries. [1][2][3][4][5][6][7][8] Specifically, solid-state polymer electrolytes (SPEs) have favorable plasticity, flexibility and scalable properties, which are compatible with commercial lithium-ion battery manufacturing processes, and they are thus regarded as the most promising solid-state electrolytes (SSEs) for lithium metal batteries. 9,10 In comparison with other SPEs, polyvinylidene fluoride (PVDF) solid polymer electrolytes have excellent flexibility and mechanical properties, along with high electrochemical and thermal stability, giving them great application potential in SSLMBs.…”

An amorphous niobium polysulfide based nanocomposite enables ultrastable all-solid-state lithium batteries

“…It is generally accepted that cathode material composites with carbon material can effectively alleviate the volume changes during the cycling process while improving electronic conductivity in all-solid-state batteries. 15,[25][26][27][28] Coating a sulfide electrolyte layer on the surface of cathode materials can effectively improve the interfacial contact with higher ionic conductivity. 29,30 In this work, an a-NbS 4.5 based nanocomposite cathode with high electronic/ionic conductivities and intimate interfacial contact was designed.…”
