1. Article Information Article Name: Molten-salt-mediated crystal facet engineering for high-performance single crystal nickel-rich cathode materials in lithium-ion batteries Equipment used: IEST Single Particle Force Properties Test System(SPFT2000) First Author: Hongyun Zhang Corresponding Authors: Jinyang Dong*, Yuefeng Su*, Lai Chen*…
Abstract Ni-rich layered oxides (NRLOs) are promising high-energy-density cathodes for lithium-ion batteries but suffer from capacity fade and interfacial instability due to chemical and mechanical degradation during cycling. While doping strategies mitigate these issues, their underlying mechanisms have remained unclear. This…

Article Information: Title: Efficient Electrochemical Exfoliation of Halogen-Terminated MXenes Mediated by Gaseous Molecules and Their Enhancement in Wear-Resistant Tribovoltaic Devices First Authors: Qi Fan, Minghua Chen, Longyi Li Corresponding Authors: Kun Liang, Laipan Zhu, Lijing Yu* Affiliations: Ningbo Institute of Materials Technology and…
Abstract Dynamic EIS (DEIS)—also called dynamic electrochemical impedance spectroscopy—measures a lithium battery’s full impedance spectrum continuously during charging or discharging, without requiring any rest period. By capturing transient electrochemical processes invisible to conventional static EIS, dynamic EIS testing enables real-time…
1. Introduction Chemical Vapor Deposition silicon(CVD/PECVD) has emerged as a key breakthrough in lithium-ion battery anode materials. Its development trajectory is closely tied to the choice of substrate, which not only influences deposition morphology and interfacial stability, but also directly…

Article Information Title: Redox-active stabilizer-enhanced structural and thermal stability of Ni-rich cathodes via an economical blending strategy First Author: Jinzhong Liu Corresponding Authors: Jinyang Dong*, Meng Wang*, Lai Chen* Affiliations: Beijing Institute of Technology, Chongqing Innovation Center of Beijing…
German battery pioneer CustomCells has filed for insolvency for its main operating entities in Itzehoe and Tübingen. The competent court in Kiel has appointed attorney Dr. Malte Köster, partner at WILLMERKÖSTER Law Firm, one of Germany’s leading insolvency law firms,…
Abstract Powder resistivity and electrode resistivity are correlated but not perfectly linear across every processing stage. Using IEST PRCD3100 powder resistivity and compaction density tester (10–350 MPa) and BER2500 electrode resistance tester (5–60 MPa, six-point measurement), a four-level study spanning…
Abstract LLZO (Li₇La₃Zr₂O₁₂) solid electrolyte is a garnet-type oxide solid-state electrolyte that offers electrochemical stability against lithium metal and high lithium-ion conductivity — making it a leading candidate for high-safety solid-state lithium batteries. A key practical challenge in LLZO preparation…
Abstract Pure silicon anodes reach a silicon anode volume expansion percentage of approximately 280% during full lithiation — roughly 28 times greater than graphite’s ~10% — making silicon anode swelling the dominant mechanical challenge in high-capacity lithium-ion battery design. This…
