Advances in preparation methods and mechanism analysis of layered double hydroxide for lithium-ion batteries and lithium-sulfur batteries

Renewable biomass-derived carbon-based hosts for lithium–sulfur batteries

“…Therefore, metal hydroxides are considered wonderful catalytic materials as a result of their structural richness and surface tenacity. 39,239,240 Yan et al 241 showed the synthesis of a composite cathode (NNH/PC/sulfur) for LSBs by using Nodus Nelumbinis Rhizomatis as a carbon source and Nibased hydroxide as a coating agent (Fig. 15a).…”

“…[35][36][37] On the one hand, BDC as sulfur hosts opens new avenues to the application of biomass energy. 20,[38][39][40] On the other hand, it has made an ineffaceable achievement in the progress of LSBs. 41,42 First, beneting from the high energy density and high carbon content of biomass, the derived carbon material skeleton can build an electron transfer network to effectively improve the conductivity of the sulfur electrode.…”

Anion‐Selective Layered Double Hydroxide Composites‐Based Osmotic Energy Conversion for Real‐Time Nutrient Solution Detection

“…[ 12,16,17 ] Layered double hydroxides (LDHs) have attracted widespread attention in optical sensors, water splitting, supercapacitors, electrocatalytic oxygen evolution, lithium batteries, and biomedical applications recently. [ 18–22 ] Positively charged layers of LDHs equip them with the capability to act as functional layers in anion‐selective nanofluidic channels.…”

Synthesis of two-dimensional layered double hydroxides: a systematic overview

“…7 The existence of interlayer anions could compensate for the positive charges that are produced by partial replacement of M 2+ by M 3+ in brucite-like host layers. 8 Due to the easy preparation, flexible structural composition, tunable interlayer space, exchangeable anions and unique physicochemical properties, 1,9,10 LDH have been regarded as attractive materials for a wide range of applications, such as catalysis, 9,[11][12][13][14][15][16][17][18][19][20][21][22][23][24] energy storage, [25][26][27][28][29][30][31] drug delivery, 32,33 sensors, [34][35][36][37] flame retardants, 38 corrosion protection, [39][40][41][42][43] removing pollutants from natural environments, [44][45][46][47] preclinical/clinical nanomedicine, 32,33,48 bioimaging, 49 optoelectronic devices, 50 light-emitting applications, 1,51 photodetectors,…”
