We introduce an innovative optical measuring device based on laser-induced breakdown spectroscopy (LIBS) for the quantitative analysis of Li in geothermal brines extraction. LIBS allows contactless and in-situ monitoring dissolved Li. In presented technique, we induce plasma surface artificial high saline fluids under flow. utilize a nanosecond Nd: YAG laser operating at 1064 nm wavelength 6 ns pulse duration. The energy is set to 26 mJ. For each sample, perform 50 shots repetition rate 1 Hz, acquired spectra are averaged. By carefully selecting parameters our system, achieve efficient measurements liquid surface, minimizing common phenomena such as splashes, bubbles, or ripples. calibrate system using samples over wide range from approximately 10 1300 mg/L, I line 670.8 nm, derive calibration curve exhibiting R2 value 99.98 %. Our implementation flowing fluid coupled with enables accurate quantification average relative uncertainty less than 2 precision measurements, compared reference values obtained ICP-OES, high, percentage difference ranging 0.1 % 7 findings demonstrate precise fluids. achieved through combined fast, contactless, capabilities LIBS, paves way its integration into extraction facilities power plants.

ABSTRACT The growing use of lithium iron phosphate (LFP) batteries has raised concerns about their environmental impact and recycling challenges, particularly the recovery Li. Here, we propose a new strategy for priority Li precise separation Fe P from spent LFP cathode materials via H 2 O‐based deep eutectic solvents (DESs). Through adjusting form metal complexes precipitation mode, above 99.95% can be dissolved in choline chloride‐anhydrous oxalic acid‐water (ChCl‐OA‐H O) DES, high efficiency 93.41% 97.40% accordingly are obtained. effects main parameters comprehensively investigated during leaching processes. mechanism pretreated is clarified rate‐controlling step heterogeneous dissolution reactions also identified. Results show that soluble phases 3 (PO 4 ) O formed after roasting pretreatment, Li(I) ions tend to C precipitates with 2− process so recovered preferentially purity 99.82%. After UV‐visible light irradiation, Fe(III) converted into Fe(II) ions, which react FeC by content, as Na PO ∙12H (99.98% purity). Additionally, plan used DES proposed performances still maintain stable three circles. method offers an approach simple process, efficiency, waste‐free DESs.

Abstract Electrodes are vital for lithium‐ion battery performance. The primary method large‐scale electrode production involves wet slurry casting methods, which encounter challenges related to solvent usage, energy consumption, and mechanical stability. Dry processed (DP) electrodes a promising alternative but struggle with rate capability properties. Here, an approach of incorporating 1 wt.% flour into DP (DP–1%F) through binder fibrillation strategy is introduced, enhances the strength, performance, cycling stability electrodes. cross‐linking protein starch in flour, along Polytetrafluoroethylene (PTFE), enable DP–1%F exhibit robust properties high flexibility. Additionally, incorporation makes primarily create large pores, reducing tortuosity, thereby endowing improved kinetic behavior. behavior suppress development irreversible phase transitions intragranular/intergranular cracks. These characteristics led superior capacity retention 80.3% after 260 cycles at 2C 4.5 V (LiNi 0.8 Co 0.1 Mn O 2 ). findings offer valuable insights high‐power, long‐life electrodes, addressing key batteries.
