What Black Diamond Structures does

Black Diamond Structures, founded in 2014 and headquartered in Austin, Texas, is a nanomaterials manufacturer that develops and commercializes discrete, functionalized carbon nanotubes under the proprietary MOLECULAR REBAR® trademark. The company's underlying process untangles traditional bundled carbon nanotubes into individual uniform tubes delivered as a liquid formulation, addressing the dispersion and contamination problems that have historically limited carbon nanotube use in industrial applications. Black Diamond Structures was established as a joint venture between Molecular Rebar Design LLC and SABIC (a multinational chemicals manufacturer), and operates an ISO 9001:2015 certified manufacturing facility with a current capacity of 3.3M Liters/year, sufficient to support over 40 GWh of high-energy density anode production. Pre-engineering and site selection are underway for an additional full-scale plant.

The company's product portfolio is organized into two primary lines. The lead-acid series (Pb1100 for automotive SLI, Pb1200 for EFB, Pb1400 for motorcycle/trike, Pb2100 for inverter, Pb2300 for eBike, Pb3200 for golf cart, Pb3400 for ESS, Pb4100 for traction, plus PbAC and PBLite) targets warranty reduction, cycle life improvement, charge acceptance, and cold-temperature performance in conventional batteries. The lithium-ion series (Li1300 water-based, Li2100 NMP-based, Li3200 dry process, Li5100 hexane-based) enables high energy density (>300 Wh/kg with silicon), fast charge (>4C), and long cycle life (>800 cycles). Products are sold in standard container sizes (10L jugs, 200L drums, 1000L totes) to enterprise battery manufacturers globally.

Black Diamond Structures operates a sales-led, direct-distribution model targeting battery manufacturers across automotive, energy storage, eMobility, and consumer electronics. Pricing is quote-based with multi-year contracts, and the company actively participates in global industry conferences (Battery Show, ELBC, FENIBAT, ABC, LABAT, CIBF) to support customer development. Customer engagement includes co-development partnerships, technical white papers, and an advanced Battery Testing Facility opened in 2017. The go-to-market is complemented by content marketing, LinkedIn presence, and partnership alliances (GreenSeal Alliance, Battery Innovation Center, IESA), with the strategic intent of embedding MOLECULAR REBAR® into manufacturer qualification cycles.

Core offering

Black Diamond Structures develops and manufactures proprietary MOLECULAR REBAR® carbon nanotube additives that are incorporated by battery manufacturers into lead-acid and lithium-ion battery production processes. The company sells application-specific product series (Pb and Li lines) in liquid form, enabling customers to achieve higher energy density, faster charging, longer cycle life, and reduced warranty returns. Products are manufactured at an ISO 9001:2015 certified facility in Austin, Texas, with a current capacity of 3.3 million liters per year.

Product overview

Black Diamond Structures develops and manufactures innovative nanomaterial products based on proprietary MOLECULAR REBAR® technology — discrete, functionalized, open-ended carbon nanotubes. The product portfolio includes two main lines: (1) Lead Acid battery solutions organized by application series (Pb1100 for automotive SLI, Pb1200 for EFB, Pb1400 for motorcycle, Pb2100 for inverter, Pb2300 for eBike, Pb3200 for golf cart, Pb3400 for ESS, Pb4100 for traction, plus PBLite and PbAC for general automotive); and (2) Lithium-Ion solutions (Li1300 water-based, Li2100 NMP-based, Li3200 dry process, and Li5100 hexane-based formulations). All products arrive in liquid form for easy incorporation into existing manufacturing processes and are available in standard container sizes from 10L jugs to 1,000L totes.
