Abstract Battery SOH (State of Health) is a result indicator — it tells you how much capacity remains, but not why it declined or what failure mechanism dominates. A cell at 80% SOH may look “only 20% worse” on a…
1. Event Recap DETROIT, MI — October 2026 — From October 12 to 15, 2026, The Battery Show North America 2026 successfully concluded at Huntington Place in Detroit, Michigan. As an established innovator in lithium-ion and next-generation battery characterization, IEST…
Abstract Battery binder distribution refers to the spatial arrangement of polymeric binder materials — typically CMC and SBR in graphite anodes — throughout the electrode coating, around active-material particles and within conductive-carbon domains. Despite accounting for less than 5% of…
Abstract Advanced solid-state battery testing requires coordinated characterization of solid-electrolyte transport, electrode–electrolyte interfaces, mechanical behavior, and electrochemical performance under controlled pressure and atmospheric conditions. The essential instruments include solid-electrolyte testing systems, pressure-controlled test molds and fixtures, electrochemical impedance spectroscopy (EIS)…
Abstract Composite electrode uniformity in a sulfide all-solid-state battery can be evaluated by measuring how electrode resistance changes with thickness: in a well-dispersed electrode, resistivity is constant through the electrode’s depth, so resistance should scale linearly with thickness, while poor…
Abstract TeraView, a UK-based company specializing in terahertz measurement technology, and IEST Instrument have entered an exclusive strategic partnership under which IEST Instrument becomes TeraView’s official partner in China for the TeraCota 3500 terahertz battery electrode inspection system. The partnership…
Abstract Choosing between natural graphite anode and artificial graphite anode materials for a lithium-ion battery comes down to a trade-off across four measurable properties: single-particle crushing strength, powder compaction density, rebound and deformation under pressure, and powder resistivity. In anode…
Abstract During battery nail penetration, real-time electrochemical impedance spectroscopy (EIS) at a 10 Hz characteristic frequency detects internal short-circuit-induced impedance changes tens of seconds to several minutes earlier than surface-temperature sensors, offering an earlier and more sensitive warning signal than…
Abstract Higher power output and better low-temperature performance in sodium-ion batteries depend heavily on porous electrode microstructure, not on active material chemistry alone. Sodium ions have a smaller Stokes radius and lower solvation energy than lithium ions, which gives sodium-ion…
Abstract High energy density and low expansion in anode-free lithium metal battery (AF-LMB) do not have to be mutually exclusive. A study from the Institute of Physics, Chinese Academy of Sciences (Beijing National Laboratory for Condensed Matter Physics), led by…
