Bio‐Inspired Electrodes with Rational Spatiotemporal Management for Lithium‐Ion Batteries

“…[211] Furthermore, the element doping, surface coating, and optimization of the synthesis process in electrode materials enable to achieve significant electrochemical performance improvement on super high discharge capacity or capacity retention of LIBs. [100] Bio-inspired electrodes are developed with self-healing coreshell structure, [30][31][32][33][34][35] self-healing binders, [36][37][38][39][40] liquid metal alloys, [41][42][43][44][45][46] microcapsules, [48][49][50] and current collectors. [51] These electrodes owning self-healing capabilities possess much more stable mechanical characteristics than conventional electrode materials that can be shortened their durability by mechanical fractures generated during cycling.…”

“…Cathode materials are prone to bulk and interfacial degradation issues, which adversely affect their electrochemical performance. [ 30 , 99 ] For instance, LiNi 1− x − y Mn x Co y O 2 (NMC) will deteriorate the electrochemical performance and structural stability during charge–discharge cycling. [ 100 , 101 ] And many commercial cathode materials (for example, LiFePO 4 , LiCoO 2 , etc.)…”

“…LIBs comprise the cathode, anode, separator, current collector, electrolyte, and battery housing. [ 27 , 28 ] Their degradation can be minimized in smart electrodes via preventive steps, like artificial interfaces, [ 29 ] coatings, [ 30 , 31 , 32 , 33 , 34 , 35 ] self‐healing binders, [ 36 , 37 , 38 , 39 , 40 ] liquid metal alloys, [ 41 , 42 , 43 , 44 , 45 , 46 , 47 ] microcapsules, [ 48 , 49 , 50 ] and current collectors. [ 51 ] For instance, silicon (Si) anode severe volume expansion of up to 300% in the lithiation state leads to solid electrolyte interface (SEI) rupture, which decreases the electrochemical performance of LIB during cycling processes, and its lifetime become shortened.…”

Controllable Synthesis of Hollow Silica Nanoparticles Using Layered Double Hydroxide Templates and Application for Thermal Insulation Coating

“…Hollow silica nanoparticles (HSN) have gained significant interest from scientists owing to their unique properties, such as low density, thermal stability, and chemically inertness. , Silica is nontoxic and easier to disperse in polymers than other fillers. This makes it become a secure option and a prospective candidate for the advancement of a variety of fields, including catalysis, − drug delivery, − biomedical application, optical materials, , and especially thermal insulation materials. − …”
