Lithium Borate/Boric Acid Optimized Multifunctional Binder Facilitates Silicon Anodes With Enhanced Initial Coulombic Efficiency, Structural Strength, and Cycling Stability

Battery Energy, Volume 4, Issue 2, March 2025.
This research introduces a novel organic‐inorganic binder: sodium alginate‐lithium borate‐boric acid (Alg‐LBO‐BA), whose three‐dimensional network effectively buffers the volumetric changes of Si, maintaining overall stability. Additionally, LBO serves as a prelithiation agent, compensating for irreversible lithium consumption during SEI formation ...

An in-situ small angle x ray scattering analysis of nanopore formation during thermally induced chemical dealloying of brass thin foils

Scientific Reports, 2018
The development of non-noble nano-porous metal materials is hindered by surface oxidation reactions and from the difficulty to generate long range order pore arrays. Dealloying is a promising route to generate such materials by selective chemical etching
