Insights Into the Electric Double-Layer Capacitance of the Two-Dimensional Electrically Conductive Metal-Organic Framework Cu3(HHTP)2
Aug 04 , 2021
Typical Synthesis Cu3(HHTP)2 was synthesised by modifying a recently published literature procedure1. A solution of Cu(NO3)2.3H2O (0.127 g, 0.526 mmol, 1.65 eq) and aqueous ammonia (35 %) solution (0.829 mL, 15.0 mmol, 47 eq) in distilled water (2 mL) was prepared. The resulting dark blue solution was added dropwise to a dispersion of 2,3,6,7,10,11-hexahydroxytriphenylene hydrate, H6HHTP.xH2O, (0....

Exploiting Anti-T-shaped Graphenes Architecture to Form Low Tortuosity, Sieve-like Interfaces for High-performance Anodes for Li-Based Cells
Jul 23 , 2021
Experimental Section Synthesis of multilayer-graphene nanowalls anchored on carbon paper：The carbon paper used was commercialized Toray carbon paper (CP). Every CP was tailored to be a wafer of 16mm in diameter. Subsequently, the mutilayer-graphene nanowalls would be grown on this CP substrate using RF-PECVD. The parameters were 200W (power), 890℃ (temperature), 30min (time) and 1000Pa (...

Toward All-Solid-State Lithium Batteries: Three-Dimensional Visualization of Lithium Migration in β- Li3PS4 Ceramic Electrolyte
Jul 19 , 2021
Experimental Preparation of LPS samples.—LPS electrolyte was prepared at Solid Power Inc. using two routes, a previously reported procedure23 for X-ray CT experiments and ball milling for EDS analysis. The LPS powder was subsequently tape cast, and then transferred to 35-μm-thick lithium foil (RockwoodLithium,0.5%Al )by cold-pressing to form LPS/Li bilayers. Symmetric Li/LPS/Li structures were ass...

Lithium Ion Conducting Polymerized Ionic Liquid Pentablock Terpolymers as Solid-State Electrolytes
Jul 12 , 2021
Abstract In this study, a lithium ion conducting polymerized ionic liquid pentablock terpolymer (PILPTP) was investigated as a battery electrolyte (Xiamen Tmaxcn Inc.) for lithium ion batteries. The ABCBA pentablock terpolymer, poly(tbS-b-EP-b-MS-b-EP-b-tbS) (tbS = tert-butyl-styrene; EP = ethylene-r-propylene; MS = 4-methylstyrene), was brominated and quaternized to covalently attach two dif...
