Lithium recovery from end-of-life Li-ion batteries(LIBs)through pyro-and hydrometallurgical recycling processes involves several refining stages,with high consumption of reagents and energy.A competitive technological alternative is the electrochemical oxidation of the cathode materials,whereby lithium can be deintercalated and transferred to an electrolyte solution without the aid of chemical extracting *** article investigates the potential to selectively recover Li from LIB cathode materials by direct electrochemical extraction in aqueous *** process allowed to recovering up to 98%of Li from high-purity commercial cathode materials(LiMn_(2)O_(4),LiCoO_(2),and Li Ni_(1/3)Mn_(1/3)Co_(1/3)O_(2))with a faradaic efficiency of 98%and negligible co-extraction of Co,Ni,and *** process was then applied to recover Li from the real waste LIBs black mass obtained by the physical treatment of electric vehicle battery *** black mass contained graphite,conductive carbon,and metal impurities from current collectors and steel cases,which significantly influenced the evolution and performances of Li electrochemical ***,due to concomitant oxidation of impurities,lithium extraction yields and faradaic efficiencies were lower than those obtained with high-purity cathode *** oxidation was found to occur within the voltage range investigated,but it could not quantitatively explain the reduced Li extraction *** fact,a detailed investigation revealed that above 1.3 V ***/Ag Cl,conductive carbon can be oxidized,contributing to the decreased Li *** on the reported experimental results,guidelines were provided that quantitatively enable the extraction of Li from the black mass,while preventing the simultaneous oxidation of impurities and,consequently,reducing the energy consumption of the proposed Li recovery method.

Closed-loop hydrometallurgical treatment of end-of-life lithium ion batteries: Towards zero-waste process and metal recycling in advanced batteries

引用

Journal of Energy Chemistry 2019年第8期28卷 220-227,I0008页

作者： Thomas Abo Atia Giuseppe Elia Robert Hahn Pietro altimari Francesca Pagnanelli Department of Chemistry Sapienza University of RomeRome 00185 Italy Waste Recycling Technologies Flemish Institute for Technological ResearchMol 2400 Belgium Technische Universitat Berlin Research Center of Microperipheric TechnologiesBerlin D-13355 Germany Fraunhofer-Institut für Zuverlassigkeit und Mikrointegration Berlin D-13355 Germany

This work presents an enhanced hydrometallurgical process for recycling lithium ion batteries. First, endof-life batteries were processed in a physical pre-treatment plant to obtain a representative electrode material. The resulting leachate was purified forth by iron-precipitation, liquid–liquid extractions, and an innovative Li–Na separation, in order to obtain valuable products. These products include high-grade graphite, cobalt oxide(Co3O4, purity 83%), cobalt oxalate(CoC2O4, purity 96%), nickel oxide(Ni O, purity89%), and lithium carbonate(Li2CO3, purity 99.8%). The recovery rate was quantitative for graphite, between 80% and 85% for cobalt depending on the nature of the recovery method, 90% for nickel, and 72%for lithium. Secondary streams were also valorized to obtain sodium sulfate(Na2SO4, purity 96%), and MnCoFe2O4 magnetic nano-sorbents according to the zero-waste concept. In order to close the loop, recycled Co3O4 and NiO were used as conversion-type anode materials for advanced lithium ion batteries showing promising performances.

Fourier and Wavelet Spectral Analysis of EMG Signals in 1-km Cycling Time-Trial

引用

Applied Mathematics 2014年第13期5卷 1878-1886页

作者： Marcelo Bigliassi Paulo Rogério Scalassara Thiago Ferreira Dias Kanthack Taufik Abrao Antonio Carlos de Moraes Leandro Ricardo altimari Group of Study and Research in Neuromuscular System and Exercise CEFE-State University of LondrinaLondrinaBrazil Department of Electrical Engineering Federal Technological University of ParanaCornélio ProcopioBrazil Department of Electrical Engineering CTU-State University of LondrinaLondrinaBrazil Laboratory of Electromyography Studies FEF-State University of CampinasCampinasBrazil

Frequency domain analyses in electromyographic (EMG) signals are frequently applied to assess muscle fatigue and similar variables. Moreover, Fourier-based approaches are typically used for investigating these procedures. Nonetheless, Fourier analysis assumes the signal as stationary which is unlikely during dynamic contractions. As an alternative method, wavelet-based treatments do not assume this pattern and may be considered as more appropriate for joint time-frequency domain analysis. Based on the previous statements, the purpose of the present study was to compare the application of Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) to assess muscle fatigue in dynamic exercise of a 1-km of cycling (time-trial condition). The results of this study indicated that CWT and STFT analyses have provided similar fatigue estimates (slope) (p> 0.05). However, CWT application represents lesser dispersion (p 0.05) according to different methods, it is important to note that these responses seem to show greater values for CWT compared to STFT for 2 superficial muscles. Thereby, we are capable of considering CWT as a reliable and useful method to take into consideration when non-stationary or oscillating exercise models are evaluated.
