Battery and energy research uses a focused set of chemicals with exacting purity and moisture limits. This sub-category supplies electrolyte components, electrode precursors and functional oxides. Examples include Ethylene carbonate and Fluoroethylene carbonate for lithium-ion electrolytes, 3-Methyl-2-oxazolidinone as a polar solvent, Copper(II) nitrate hydrate at 99.999% for electrode synthesis, Iron(III) fluoride trihydrate for conversion cathodes, and Lanthanum strontium cobalt ferrite (LSCF) for solid oxide fuel cell cathodes.
For electrolytes, water content in ppm and trace metals are the key figures, as both shorten cycle life. Fluoroethylene carbonate is added at a few percent to build a stable solid electrolyte interphase on silicon and graphite anodes. LSCF is chosen for its mixed ionic and electronic conductivity at intermediate temperatures, and its particle size affects electrode performance.
- Carbonate solvents and film-forming additives
- Metal salts and fluorides for electrode synthesis
- Perovskite oxides for fuel cells and electrolysers
Moisture-sensitive items are packed under argon. Each lot ships with a COA and SDS.
Battery & Energy Materials: questions buyers ask
Why add fluoroethylene carbonate to an electrolyte?
FEC reduces at the anode before other solvents and forms a thin, flexible, fluoride-rich interphase layer. This layer protects silicon and graphite anodes from continued electrolyte breakdown and copes better with volume changes. A few percent of FEC can markedly improve cycle life, especially for silicon-containing anodes.
How should ethylene carbonate be handled?
Ethylene carbonate is a solid at room temperature, melting near 36 °C, so it is warmed gently to liquefy before mixing. Battery grades are very dry and must be handled in a glovebox or dry room. Exposure to moist air raises water content quickly, which harms cell performance.
What is LSCF used for?
Lanthanum strontium cobalt ferrite is a perovskite oxide that conducts both oxide ions and electrons. It is a common cathode material for intermediate-temperature solid oxide fuel cells and an oxygen electrode for electrolysers. Powder particle size and phase purity influence electrode activity and long-term stability.
