The Extra Mile

The Extra Mile’s silicon based anode material is a breakthrough innovation, increasing energy capacity while leveraging a mechanical Si/C process - setting us apart from start-ups, pilot, and research projects. By optimizing material efficiency, we ensure rapid sample access and reliable support, while delivering lower resistance, higher capacity, and minimized swelling for faster charging and extended travel.

Every gram and every millimeter inside a scooter battery pack is a tradeoff between range, weight, cost, and cycle life. The Extra Mile's silicon-based anode material, now in pilot production, gives your engineering team more headroom on all four. Higher energy density means more range from the same pack, or the same range from a smaller, lighter one. Lower resistance and minimized swelling extend cycle life and reduce warranty risk. Meaning your riders get more range from a lighter, longer-lasting pack.

Maximizing battery performance while controlling costs is key to EV market success. The Extra Mile’s Si/C anode material integrates nano-silicon into a carbon matrix, enabling higher energy density in the battery packs, extended cycle life, and efficient lithium utilization. It delivers enhanced stability, fast charging, and seamless integration into existing processes.

Umicore and Hyosung stand behind The Extra Mile. One brings deep expertise in advanced materials, refined over decades of chemistry, processing, and circular supply. The other brings industrial scale across multiple sectors, with the manufacturing footprint to support new technologies as they grow. That backing shapes how we work and what we can deliver.

A battery material can excel in the lab and still fail on the path to industrial adoption, because every change affects manufacturing, cell design, cost, qualification, and supply. Moving from grams to kilotons means proving repeatability, process compatibility, and system-level value through years of testing. Our whitepaper maps the constraints between innovation and adoption, so teams know what a new material must prove before the industry commits.

A battery has to pass years of testing before it ships in a car, so the route a company picks in 2026 shapes what it can sell well into the 2030s. The options run from a modest, low-risk gain to an all-in bet on maximum range, and each carries costs that only show up later. Our whitepaper walks through where each path pays off and where it hurts, so the decision gets made with open eyes.
