Electrolytes, Salts, Solvents & Additives

CORE ELECTROLYTE SOLUTIONS

I. SALTS

Salts are the core component in electrolytes that provide ionic charge carriers. ATOMFAIR possesses more than 130 types of salt products featuring different cation/anion combinations. All products undergo high-purification processing, with routine moisture strictly controlled below 50 ppm (and ionic liquids can be controlled as low as 100 ppm).

Lithium Salts: The product spectrum covers hexafluorophosphates (LiPF₆), bis(acyl)imide salts (LiTFSI, LiFSI, LiFTFSI), borates/oxalates (LiBOB, LiDFOB, LiODFB), phosphates (LiPO₂F₂, LiDODFP), trifluoromethanesulfonates, as well as inorganic halides and inorganic carbonates. It fully satisfies the full-scenario requirements of liquid-phase lithium-ion, high-voltage, lithium-sulfur, and solid-state electrolyte systems.

Other Metal Salts: Oriented toward next-generation battery architectures including sodium (Na), potassium (K), magnesium (Mg), zinc (Zn), and calcium (Ca) battery systems. Typical flagship products include NaPF₆, NaTFSI, KTFSI, MgTFSI, ZnTFSI, and CaTFSI, which are fully and seamlessly compatible with existing solvent and additive systems.

Ionic Liquids: The cation portfolio covers imidazoliums (dialkyl, functionalized, sulfonic acid functionalized, 2,3-dimethyl), pyrrolidiniums (PY13), and piperidiniums (Pl₁₃). The anion portfolio covers NTf₂, FSI, BF₄, PF₆, Cl, Br, Acetate, DCA, SCN, EtSO₄, SbF₆, HSO₄, and H₂PO₄. They simultaneously feature high flame retardancy, a wide electrochemical window, and high thermal stability, making them ideally suited for electrolyte modification, solid-state electrolyte plasticization, and gel electrolyte polymerization.

Core Value: Complete system salts can be fully sourced in a one-stop shop. The high-purification treatment ensures that impurities are stringently controlled, which significantly minimizes batch-to-batch variations brought to customers by purchasing across cross-vendor suppliers.

II. SOLVENTS

Solvents directly dictate and influence the ionic conductivity, operating temperature range, and total safety performance of the electrolyte. ATOMFAIR provides over 25 high-purity solvents, featuring deep drying and tightly sealed packaging, which can be directly utilized for battery cell electrolyte injection processes.

Carbonates: Includes EC, PC, DMC, DEC, and EMC. They feature a high dielectric constant and are exceptionally suitable as the primary host solvents for lithium-ion and sodium-ion batteries.

Fluorinated Carbonates: Includes FEC alongside various trifluoroethyl/hexafluoroisopropyl carbonates. They actively elevate and optimize electrolyte structural stability under high voltage thresholds (≥4.35V).

Ethers: Includes DME, DOL, Diglyme, TEGDME, and PGDME. They are explicitly adapted for lithium-sulfur batteries, lithium-metal batteries, and extreme low-temperature chemical systems.

Fluorinated Ethers / Fluorinated Phosphates: Includes TTE, TFEP, TDFEP, and TMP. These are deployed as specialized flame-retardant co-solvents to comprehensively boost cell safety performance.

Nitriles: Includes SN, ADN, and HTCN. These serve as high-boiling-point additives and co-solvents to effectively passivate and stabilize the cathode electrolyte interface (CEI).

Carboxylic Esters: Includes PP, Ethyl Acetate, and Ethyl Propionate. Deployed to reduce fluid viscosity and significantly improve low-temperature kinetic performance metrics.

Core Value: Comprehensive category coverage with ready-to-use high-purity solvents eliminates additional purification steps for customers, thereby drastically shortening the validation period for new electrolyte formulations.

III. ADDITIVES

The blending dosage of additives typically does not exceed 5%, yet they can directionally optimize SEI/CEI structures, suppress gassing behaviors, provide flame retardancy, and inhibit dendrite propagation. ATOMFAIR possesses more than 30 products, with the main product specifications reaching a purity threshold of ≥99.95%.

Anode Film Forming: Includes VC, FEC, and PS. Deployed to optimize SEI film toughness, flexibility, and overall battery cyclic lifetime parameters.

Cathode Film Forming / High Voltage: Includes DTD, PTS, SN, ADN, and HTCN. Stabilizes high-voltage cathode interfaces and actively minimizes transition metal dissolution behaviors.

Flame Retardant: Includes TMP, TFEP, and PFNP. Explicitly formulated to optimize and increase total cell thermal safety and abuse performance.

Lithium Salt-Type Multi-Functional: Includes LiBOB, LiDFOB, LiPO₂F₂, and LiDODFP. These agents simultaneously participate in passivating film growth, lowering structural impedance, and blocking current collector aluminum foil corrosion.

Dendrite Inhibitors: Includes sulfonic acid functionalized ionic liquids and CsPF₆. Formulated for high-performance lithium-metal negative electrodes and next-generation anode-free setups.
