SP250-Li Conductive Carbon Black
Acetylene conductive grade with a battery-oriented TDS row. Oil absorption 260–290 ml/100g; Fe ≤10 ppm; resistivity ≤0.20 Ω·cm. Map: Li-ion, Na-ion, solid-state and fuel cells.
SP250-Li is an acetylene-process grade in the same SP series as SP150. The “Li” suffix on the TDS marks it as a battery-oriented row: tighter heating-loss and ash limits than SP150, a published iron limit, and a slightly lower resistivity ceiling. CAS No. 1333-86-4 · H.S. Code 2803000000 · general chemical grade. Fitness for any cell chemistry still has to be proven in your own electrode and process work — the TDS is a screening sheet, not a cell qualification.

Note: figures above are TDS specification ranges for reference. Delivery specifications follow the technical agreement we confirm with you. Please validate the grade in your own formulation and process. Safety information sits in the SDS (EU REACH), not in the TDS table.
Battery and fuel-cell uses on the TDS map
The application map marks SP250-Li for four lines only:
- Sodium-ion batteries
- Lithium-ion batteries
- Solid-state batteries
- Fuel cells
It does not mark SP250-Li for silicone, rubber, coatings, plastics, cable compounds or flooring — those dots sit on other columns. If you are screening a conductive additive for an electrode, start here or with the neighbouring Li-suffixed rows on the same sheet; if you need silicone or rubber conductivity, look at SP150 instead.

How this grade differs from SP150
Against the SP150 row on the same TDS, SP250-Li publishes a higher oil-absorption window (260-290 vs 220~270 ml/100g), a lower iodine-absorption window (65±5 vs 85±10 g/kg), tighter heating loss (≤0.20% vs ≤0.50%) and ash (≤0.10% vs ≤0.50%), a slightly more alkaline pH (9.0±1 vs 8.5±1), resistivity ≤0.20 Ω·cm rather than ≤0.25 Ω·cm, and Fe ≤10 ppm (SP150 has no published Fe figure). The TDS also lists SP150-Li as a separate neighbour (oil absorption 240~280 ml/100g, Fe ≤30 ppm); that grade is not this page.
Downloads and handling notes
Alongside the TDS we publish an EU REACH SDS for carbon black (CAS 1333-86-4) and three SGS reports dated 26 June 2026 on a submitted carbon black sample: REACH Candidate List SVHC screening (253 substances, results ≤0.1% w/w, plus one potential SVHC also ≤0.1% w/w); EU RoHS Directive (EU) 2015/863 amending Annex II to 2011/65/EU (Pass); and halogen testing to IEC 62321-3-2:2020 (fluorine, chlorine, bromine and iodine reported ND on that sample; MDL 20 mg/kg for F and 50 mg/kg for Cl, Br and I). Those reports describe the submitted sample — they are not a substitute for the grade TDS or a lot COA. SP250-Li is not named as its own model number on the SDS service summary; the SDS covers carbon black as a substance. Ask us if you need that stated for a customer file.

The TDS storage note is the same across these sheets: keep the material in a cool, dry, well-ventilated warehouse; protect it from moisture; guard against dust inhalation and skin contact; store it apart from strong oxidants and do not mix-store. For classification and safe handling, follow the SDS rather than the short TDS footnote. MOQ and Incoterms are not listed here.
