3D printed silicon-few layer graphene anode for advanced Li-ion batteries

Abstract

Novel 3D printed anodes based on Si and wet-jet milling-exfoliated few-layer graphene are produced by fused diffusion modelling (FDM) technique and used in Li-ion batteries.

Transition metal dichalcogenides as catalysts for the hydrogen evolution reaction: The emblematic case of “inert” ZrSe2 as catalyst for electrolyzers

“…[55] As facilitated by the layered structure of the 1T-ZrSe 2 , bulk-ZrSe 2 sample was exfoliated to obtain 2D flakes through prototypical ultrasonication-assisted liquid-phase exfoliation (LPE) in anhydrous isopropyl alcohol (IPA). Noteworthy, other industrial LPE methods, for example wet-jet milling exfoliation, [65][66][67][68] can be prospectively used for the exfoliation step of the bulk-ZrSe 2 , as demonstrated for other layered materials. [65][66][67][68] The unexfoliated crystals were discarded from the resulting dispersion by means of sedimentation-based separation via ultracentrifugation, [69,70] obtaining the first set of samples named ex-ZrSe 2 .…”

A second set of samples was obtained by adding a solution of Nickel(II) chloride (NiCl 2 ) salt into the LPE-produced ex-ZrSe 2 , with a ZrSe 2 :Ni weight ratio of 5:1, followed by 1 hour of ultrasonication.…”

Additive manufacturing for advanced rechargeable lithium batteries: A mini review

“…For cathode materials, some widely used cathode materials have been successfully applied for 3D printed lithium batteries including lithium cobalt oxides (LiCoO 2 ) (Kohlmeyer et al, 2016), lithium manganese oxides (LiMn 2 O 4 ) (Li et al, 2017), lithium transition-metal phosphates (LiMn 1-x Fe x PO 4 ) (Hu et al, 2016), etc., as well as other materials with higher capacities involving carbon materials (graphite and graphene) (Mensing et al, 2020;Zhang et al, 2021), silicon materials (Beydaghi et al, 2021), and quantum dots (Zhang et al, 2018b). For anode materials, some conductive frameworks such as carbon and 2D MXenes (Ti 3 C 2 T x ) can severe as current collectors for hosting Li (Wei et al, 2021).…”

Sulfonated NbS2-based proton-exchange membranes for vanadium redox flow batteries

“…Major efforts are currently underway to increase the dependence on renewable energy sources (e.g., wind, solar, wave, and biofuel) while limiting greenhouse gas production. [1][2][3] However, the storage of energy produced from renewable energy sources for use in on-demand applications is an essential requirement for achieving the transition to fossil fuel-free economies. 4 High-efficiency energy storage devices are pro-gressively developing to meet an ever-growing energy demand with an increasing share of renewable energy sources.…”
