In a world grappling with unprecedented environmental challenges, the quest for sustainable, renewable energy solutions is paramount. One of the primary challenges is finding sustainable sources of battery materials that minimize EV battery carbon footprints. XBM USA and Tanac, Brazil’s leading sustainable tannin bioproduct manufacturer over the past few years have collaborated to harness the power of sustainable vegetal extraction constituents, such as tannin, for use in what could become the world’s most sustainable EV battery.

Most EV lithium batteries produced today, primarily in Asia, use hard to find, expensive materials such as nickel, graphite and cobalt, and for the most part use coal to power their massive battery production facilities with a large ESG carbon footprint. Over the past few years, an accomplished team of US advanced lithium battery material and technology developers from XBM USA has been working under wraps in the US and Brazil on an ultra-low carbon transformational battery material and high-performance next generation aviation, EV, 3C, and BES battery technology platform named CarbonX™.

According to XBM USA CEO P.K. Roberts, “XBM chose Tanac as its exclusive tannin supplier because of the outstanding sustainable ESG practices Tanac employs to produce their biomass-based materials.”

Recently, at a workshop forum at the CTNano Research Institute in Belo, Horizonte, Brazil, XBM USA presented its most recent CarbonX Lithium-Sulfur Battery (LSB) cell performance findings as part of a partially funded Brazilian government research project. The CarbonX LSB test results over the past 6 months showed that the XBM team had produced and demonstrated a very promising lithium-sulfur battery prototype made in part from biomass materials and sulfur industrial byproducts with almost double the energy density (420Wh/kg) vs the best EV batteries today (180-230Wh/kg). The tannin in the CarbonX Li-S battery was supplied by Tanac, a Brazilian forest-based manufacturer of sustainable tannin biosolutions. The preliminary research results were published in a 2022 Electrochemistry Communications article named “A biomass-based cathode for long-life lithium-sulfur batteries.”

At the end of the CTNano workshop presentation, XBM and Tanac signed a MOU for Tanac to supply XBM over the following years with optimized tannin samples leading to large supply volumes of Tanac tannin material for use in the XBM CarbonX™ Lithium-Sulfur Battery, the specific details were not disclosed. According to XBM CEO P.K. Roberts, “XBM chose Tanac as its exclusive tannin supplier because of the outstanding sustainable ESG practices Tanac employs to produce their biomass-based materials.”
