Monolithic Nanoporous Zn Anode for Rechargeable Alkaline Batteries
Jun 28 , 2021
Congcheng Wang,# Guoyin Zhu,# Pan Liu, and Qing Chen* METHODS Battery Assembly and Testing. Ni−Zn batteries were assembled into coin-type cells (CR2032) with a Zn anode, either the compressed nanoporous Zn (∼0.36 cm2 in size) or a pasted electrode comprising Zn powder (90 wt %, Aldrich), polyvinylidene fluoride (Arkema Kynar), and a NiOOH cathode (650 mAh, GP Batteries). Tin foil was used as the a...

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...

Silicon nanopillar anodes for lithium-ion batteries using nanoimprint lithography with flexible molds
Jul 14 , 2021
Eric Mills, John Cannarella, Qi Zhang, Shoham Bhadra, Craig B. Arnold, and Stephen Y. Chou II. EXPERIMENT B. Assembly of anodes The cell preparation and assembly process has four key steps: (1) transfer to an Ar-filled glovebox, (2) Li-disk preparation, (3) separator preparation, and (4) final assembly. In step (1), after etching, the anodes were moved into an Ar-filled glove...

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...

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 (...
