Electrolyte Battery Materials

An electrolyte is a substance that conducts electricity when dissolved in a solvent and is essential to the proper functioning of a battery. For lithium-ion batteries, the electrolyte usually consists of a lithium salt like lithium hexafluorophosphate dissolved in a blend of organic solvents like ethylene carbonate and diethyl carbonate.

Our battery-grade electrolytes offer the most consistent and reliable performance by strictly limiting trace water and acid impurities. We understand that customers have different needs when it comes to electrolyte formulation, so we offer both preformulated electrolytes that can be used right out of the bottle, as well as all the battery-grade electrolyte materials, such as solvents, electrolytic salts, and additives, that customers need to formulate their own electrolytes in-house. This flexibility and customization ensure that our customers get exactly the right solutions for their needs, whether they are working on coin cell testing or pouch cell prototyping.

Cathode Battery Materials

In a lithium-ion battery, the cathode is the electrode that acquires electrons from the external circuit and plays a critical role in maintaining charge balance by simultaneously intercalating lithium ions. Typically, the cathode consists of a cathode active material (CAM, ~90%), polymeric binder (~5%), and a conductive additive (~5%). These materials are mixed to form a slurry, which is then cast onto an aluminum foil current collector to create the cathode.

The choice of CAM is a key factor that determines the energy density of the lithium-ion battery through cell voltage and capacity. Our high-quality CAMs include popular materials such as lithium cobalt oxide (LiCoO₂), lithium manganese oxide (LiMn₂O₄), lithium iron phosphate (LiFePO₄ or LFP), and lithium nickel manganese cobalt oxide (LiNiMnCoO₂ or NMC), each offering strengths and tradeoffs with energy density, thermal stability, and cost-effectiveness. We also offer ready-to-cast slurries and ready-to-use electrode sheets for our customers who want to skip the time and labor of cathode processing and expedite their research.

Anode Battery Materials

Our high-performance anode material portfolio provides excellent porosity and conductivity, good durability and light weight at low cost. We offer natural and artificial graphite, powdered graphene, activated carbon, carbon black, conductive additives, mixed metal nanocomposites, lithium titanate (LTO), titanium oxide, and surface-functionalized silicon to increase battery capacity and power density.

Solid-state Battery Materials

Solid-state batteries use a solid electrolyte to replace the liquid electrolyte used in current lithium-ion batteries and are one of the most promising next-generation battery technologies to improve safety and energy density. Solid electrolytes can be made from a range of materials, such as ceramics, polymers, and glasses, each offering unique advantages and properties. Our high-quality solid-state electrolyte materials are available in a variety of compositions, including sulfides, oxides, and halides. The materials are carefully synthesized with controlled particle size, crystallinity, and purity to provide reliable and reproducible performance in electrochemical cells.

Sodium-ion Battery Materials

Sodium-ion batteries are an emerging alternative to lithium-ion batteries that offer significant advantages such as lower material costs, improved safety, and abundant resources. Sodium-ion batteries use sodium ions instead of lithium ions to store and transfer electric charges.

We provide a range of high-quality sodium-ion battery materials. Our sodium-ion materials include electrolytes, cathode and anode active materials, precursors, and electrode sheets, all designed to deliver high energy density, long cycle life, and consistent, reproducible performance.

Battery-grade Precursors

Precursors are the compounds used to make the cathode or anode active materials. We offer a range of high-quality salt precursors for synthesis of battery materials, including battery-grade lithium salts such as lithium hydroxide and lithium carbonate and high-purity transition metal salts such as cobalt, manganese, nickel, aluminum, and iron salts. Whether precursors for solid-state reactions, co-precipitation, or wet chemical processing, we have the high-purity precursors to help our customers synthesize top-performing battery materials reliably and reproducibly.
