Optimizing Average Electric power During the Charging of Lithium-Ion Batteries Through the Taguchi Method

Transactions of Tianjin University 2024年第2期30卷 152-166页

In recent times, lithium-ion batteries have been widely used owing to their high energy density, extended cycle lifespan, and minimal self-discharge rate. The design of high-speed rechargeable lithium-ion batteries faces a significant challenge owing to the need to increase average electric power during charging. This challenge results from the direct influence of the power level on the rate of chemical reactions occurring in the battery electrodes. In this study, the Taguchi optimization method was used to enhance the average electric power during the charging process of lithium-ion batteries. The Taguchi technique is a statistical strategy that facilitates the systematic and efficient evaluation of numerous experimental variables. The proposed method involved varying seven input factors, including positive electrode thickness, positive electrode material, positive electrode active material volume fraction, negative electrode active material volume fraction, separator thickness, positive current collector thickness, and negative current collector thickness. Three levels were assigned to each control factor to identify the optimal conditions and maximize the average electric power during charging. Moreover, a variance assessment analysis was conducted to validate the results obtained from the Taguchi analysis. The results revealed that the Taguchi method was an eff ective approach for optimizing the average electric power during the charging of lithium-ion batteries. This indicates that the positive electrode material, followed by the separator thickness and the negative electrode active material volume fraction, was key factors significantly infl uencing the average electric power during the charging of lithium-ion batteries response. The identification of optimal conditions resulted in the improved performance of lithium-ion batteries, extending their potential in various applications. particularly, lithium-ion batteries with average electric power of 16 W and 17

preface to the special topic on active matter

National Science Open 2024年第4期3卷 4-6页

作者： Ran Ni Mingcheng Yang h.p.Zhang School of Chemistry Chemical Engineering and Biotechnology Nanyang Technological University Beijing National Laboratory for Condensed Matter physics and Laboratory of Soft Matter physics Institute of Physics Chinese Academy of Sciences School of physics and Astronomy Institute of Natural Sciences and MOE-LSC Shanghai Jiao Tong University

Active matter refers to systems composed of individual units that consume locally stored energy to generate mechanical motion. Examples of active matter include biological entities such as schools of fish, flocks of birds, bacterial colonies, and synthetic systems such as self-propelled colloidal particles and engineered nanobots. The study of active matter seeks to provide understanding for complex behaviors and emergent phenomena arising from interactions of these energy-consuming units, with implications for fields ranging from physics and biology to materials science and robotics.

Neurodegenerative diseases,such as Alzheimer’s disease,parkinson’s disease,and amyotrophic lateral sclerosis,despite the diversity in clinical symptoms,share a striking feature at the cellular level:the accumulation of insoluble aggregates of misfolded proteins that are sequestered in intraneuronal inclusion *** mutations in disease-associated proteins that render them aggregation-prone,the decline of protein homeostasis(***)with aging is also believed to be a contributing factor to the accumulation of protein aggregates.

proteins as nanomagnets and magnetoreceptors

Zoological Research 2024年第4期45卷 831-832页

作者： p.J.hore Department of Chemistry University of OxfordUK

It is an appealing notion that a protein molecule could act as a nanomagnet.A genetically encodable biomolecule with a permanent magnetic moment at room temperature could have a range of applications:a magnetogenetic actuator,a magnetic tag for purifying and immobilizing enzymes,a contrast agent for magnetic resonance imaging,and a basis for a biomimetic magnetic sensing device,to name just a few.A magnetic protein could perhaps also function as the sensor in the magnetic compass that enables small songbirds to navigate the huge distances between their breeding and wintering *** though such possibilities may be,how realistic are they?
