Why is PVDF unsuitable as a binder for silicon anodes? 2026 Update

February 7, 2026

Why is PVDF unsuitable as a binder for silicon anodes? I. Silicon Anodes?     Core Characteristics: 1. Extremely High Theoretical Specific Capacity. Use Neware battery cyclers to test your battery capacity Based on its alloying reaction mechanism (Li₂₂Si₅), silicon has a theoretical specific capacity as high as approximately 4200 mAh/g. This is more than 10 times that of current commercial graphite anodes (~372 mAh/g, based on intercalation). This is the fundamental reason why research revolves around silicon and is the key to achieving next-generation high-energy-density lithium-ion batteries. 2. Suitable Operating Potential The lithiation potential of silicon is approximately 0.1–0.5 V (vs. Li/Li⁺), which is higher than the lithium plating

How to analyze the OCV curve of an LFP battery? 2026 post

February 6, 2026

How to analyze the OCV curve of an LFP battery? The Open Circuit Voltage (OCV) method is one of the primary techniques used to estimate a battery’s State of Charge (SOC). Consequently, investigating the SOC-OCV curves of Lithium Iron Phosphate (LFP) batteries is of great importance. Current research focuses predominantly on the precise calibration of SOC-OCV curves and the exploration of specific influencing factors. However, there are few reports regarding the effects of active materials, capacity fade, silicon doping, and lithium supplementation on OCV curves. Furthermore, there is a lack of explanation concerning the cause of the voltage step near 60% SOC in LFP/graphite batteries, as well as the relationship

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
