Syens Elemental Analytical Instruments for New Energy Materials

Syens is a leading provider of advanced analytical instruments tailored for high-precision elemental analysis, particularly in demanding sectors like new energy materials. These materials, including lithium-ion battery electrodes (positive and negative), solid-state electrolytes, and other energy storage components, require rigorous quality control to ensure optimal performance, safety, and longevity. Impurities such as oxygen, nitrogen, hydrogen, carbon, and sulfur can degrade electrochemical properties, reduce battery efficiency, or pose safety risks like thermal runaway. Drawing parallels from aerospace applications—where precise elemental analysis of metals like titanium alloys is essential to mitigate issues such as embrittlement and cracking—Syens products enable similar reliability in new energy development. Below, we detail the specific applications of Syens' key analyzers in this field.

High-Frequency Carbon and Sulfur Analyzer

This instrument excels in rapid, accurate determination of carbon and sulfur content, which directly impacts the conductivity, structural integrity, and thermal stability of new energy materials. In aerospace, carbon and sulfur measurements in alloys like titanium and steel ensure hardness and workability for high-stress components; similarly, in new energy, they prevent impurities that could compromise battery performance.

Key Applications in New Energy Materials:

• Battery Electrode Materials (Positive and Negative): Analyzes carbon content in graphite anodes or cathode precursors (e.g., lithium cobalt oxide or nickel-manganese-cobalt) to verify purity levels below ppm thresholds, ensuring high capacity and cycle life. Sulfur detection helps identify contaminants that could lead to sulfurization and capacity fade.

• Solid-State and Electrolyte Materials: Measures sulfur in sulfide-based solid electrolytes to avoid side reactions that degrade ionic conductivity.

• Other Solid Materials: Suitable for titanium dioxide (used in photoelectrochemical cells) and refractory materials in battery casings, providing data for process optimization in manufacturing.

Benefits: The high-frequency induction furnace operates at temperatures above 2,000°C in a pure oxygen atmosphere, delivering results in seconds with flexible infrared detection ranges. This supports R&D in electric vehicle (EV) batteries and renewable energy storage, aligning with industry standards for impurity control.

Full Spectrum Direct Reading Spectrometer

This versatile tool provides comprehensive multi-element analysis for alloy composition, crucial for alloyed new energy materials where trace elements affect energy density and stability. In aerospace, spectrometers verify alloy ratios in titanium and superalloys for corrosion resistance; in new energy, they ensure precise doping and homogeneity in electrode alloys.

Key Applications in New Energy Materials:

• Alloy-Based Electrodes and Current Collectors: Analyzes non-ferrous alloys like aluminum, copper, or nickel-based materials in battery foils and tabs, detecting elements such as Si, Fe, Mn, and Ti to maintain low resistance and prevent dendrite formation.

• Advanced Composites and Coatings: Evaluates ferrous and non-ferrous alloys in structural battery components, including vanadium or titanium additions for enhanced durability in high-power applications like EV drivetrains.

• Rare Earth and Catalyst Materials: Quantifies elements in rare-earth-doped cathodes (e.g., lanthanum in lithium-ion variants) for improved charge-discharge efficiency.

Benefits: Offering full-spectrum detection with high resolution, it handles diverse sample forms (solids, powders) and supports rapid screening in production lines, reducing defects in scalable battery manufacturing.

Oxygen, Nitrogen, and Hydrogen Analyzer

Gaseous impurities like O, N, and H are particularly detrimental in new energy materials, causing oxidation, nitridation, or hydride formation that reduces ionic mobility and safety. Referencing aerospace practices, where ONH analysis in titanium prevents embrittlement for engine reliability, this analyzer ensures new energy components withstand operational stresses like high-temperature cycling.

Key Applications in New Energy Materials:

• Electrode and Powder Materials: Measures low-ppm levels of oxygen and hydrogen in lithium metal anodes or silicon-graphite composites to mitigate volume expansion and gas evolution during charging.

• Alloys and Ceramics: Analyzes ferrous/non-ferrous alloys (e.g., steel casings) and ceramics (solid electrolytes) for nitrogen content, which can form insulating phases; ideal for rare earth powders in next-gen batteries.

• Powder Metallurgy for Energy Storage: Flux-assisted fusion at up to 3,000°C releases embedded gases from samples (100–1,000 mg), ensuring repeatability for quality assurance in powdered precursors.

Benefits: Using inert gas fusion with an impulse furnace, it achieves precise quantification (ppm to 2%) compliant with standards, facilitating safer, higher-efficiency batteries for EVs and grid storage.
