How to assemble and test a three electrode pouch cell? The Role of Three-Electrode Systems in Battery Analysis When a battery undergoes low-temperature or high-rate charging, lithium ions reaching the anode may fail to intercalate into the graphite layers in time, leading to lithium plating. This is a polarization phenomenon caused by kinetic limitations. Therefore, to better investigate various electrochemical properties, a reference electrode is often introduced. This allows for the independent measurement of the cathode and anode potentials relative to the reference, as well as their potential variations under different testing conditions. By utilizing a three-electrode system, researchers can perform comprehensive, in-situ analysis on several fronts: the film-forming reactions

Graphite Anodes Explained: Chemical vs. Electrochemical Lithiation in Lithium-Ion Batteries 2026 update

Graphite Anodes Explained: Chemical vs. Electrochemical Lithiation in Lithium-Ion Batteries Source: WeChat Official Account “Brother Radish” Graphite anode materials have maintained a dominant position in the lithium-ion battery industry since their discovery. While cathode options have diversified significantly—ranging from Lithium Iron Phosphate (LFP) and Lithium Cobalt Oxide (LCO) to NCM Ternary cathodes—graphite remains the undisputed first choice for the anode. But why is this the case? Join us as we trace the developmental history of the graphite anode and explore how it established its long-standing “dynasty” in the battery world. I. The Discovery of Chemical Lithiation in Graphite (1950s) In 1955, the French chemist A. Hérold immersed graphite into molten

Impact of Testing Fixtures on the Cycle Performance of LFP Batteries 2026 post

February 4, 2026

Impact of Testing Fixtures on the Cycle Performance of LFP Batteries Cycle performance is a fundamental metric for evaluating the service life of lithium-ion batteries. It is influenced by a wide range of factors, including material properties, cell structure, moisture content, and manufacturing processes. Furthermore, external parameters such as temperature, cycling protocols, and mechanical pressure also significantly impact the cycle performance of lithium-ion batteries. To investigate the effect of testing fixture constraints on cycle performance and to enhance the reliability of pouch cell testing during the system optimization phase, this study focuses on a 3.65 Ah LiFePO4 (LFP)/graphite pouch cell. Two types of testing fixtures were evaluated: non-constrained fixtures, utilizing

CATL’s -30°C Sodium-Ion Battery, 800km Driving Range?! Source: WeChat Official Account “Electric Vehicle Commune” Hello everyone, I am the President of the Electric Vehicle Commune. 2025 can be described as a year of critical milestones for China’s new energy vehicles (NEVs). According to statistics from the China Passenger Car Association (CPCA), the retail penetration rate of NEV passenger vehicles grew to 54% in 2025. This marks the first time it has surpassed the 50% threshold, setting a new historical record—a 6.4 percentage point increase compared to 47.6% in 2024. This signifies that in the passenger vehicle sector, NEVs have become the primary choice for car buyers, while internal combustion engine
