With the undergoing unprecedented development of lithium-ion batteries (LIBs), recycling end-of-life has become an urgent task considering demand for critical materials, environmental pollution, and ecological impacts. Selective recovery targeted element(s) is becoming a topical field that enables metal in short path with highly improved material efficiencies. This research demonstrates process selective spent Ni-Co-Mn (NCM)-based battery by systematically understanding conversion mechanisms...
A way of directly repairing spent lithium-ion battery cathode materials is needed in response to environmental pollution and resource depletion. In this work, we report a green repair method involving coupled mechanochemistry solid-state reactions for batteries. During the ball-milling process, an added manganese source enters into degraded LiMn2O4 (LMO) crystal structure order fill Mn vacancies formed by deficiency due Jahn–Teller effect, thereby LMO's chemical composition. An carbon acts...
As the pressure on resources and environment from spent lithium-ion batteries (LIBs) continues to grow, an efficient low-cost method of recycling process is necessary for battery sustainability. Here, we exhibit a low-temperature acid-free leaching based intermediate-products extracting recycle LiNi1/3Co1/3Mn1/3O2 (NCM111). Different conventional salt-assisted roasting generating sulfates metallic oxides, roasted products metal-ammine-sulfate complex salts were obtained at optimal...
Abstract Nanosized tungsten powders were fabricated by solution combustion synthesis combined with hydrogen reduction. The powder had a size of 20 nm but possessed large numbers lattice defects. fracture surface images at different temperatures show that the as-synthesized could be sintered via pressureless process to relative density up 95.78% 1773 K. Kinetic analysis suggests grain-boundary diffusion is one primary mechanisms mass transport during intermediate stage sintering. sintering...
To develop highly efficient catalysts with low Pt content for electrocatalytic methanol oxidation reaction (MOR) is meaningful yet still challenged. Here, PtPdCdZnCo ultrafine high-entropy alloy (uf-HEA) nanoparticles (～2.6 nm) were achieved by a facile one-pot chemical synthesis. As MOR catalyst, the uf-HEA displays ultrahigh mass activity of 2.86 and 11.1 A mgPt-1 in acidic alkaline environments, respectively. That best catalyst so far comparing other reported Pt-based catalysts. Study...
The conventional flame brazing using combustible gas and oxygen as the heat source for welding, it has problems such high energy consumption, no environmental protection, potential safety hazard so on. In order to avoid above problems, based on characteristics of plasma arc brazing, a novel method (PFB) is proposed. process, non-transfer converted into source, density formed by compressed through enough brazing. this paper, equipment process was developed, including key technologies...
