TaiSan and SELANA to explore next-generation sodium batteries for urban micromobility

Cambridge, UK & Amsterdam, Netherlands - 26 October 2026

TaiSan, the UK deep-tech company developing next-generation sodium batteries for micromobility, has announced a collaboration with SELANA, the Dutch electric-mobility company behind the first legal e-scooters and urban mobility solutions. The partnership will explore how TaiSan's sodium-battery technology could power the next generation of SELANA products and services, as SELANA prepares to enter the UK market.

TaiSan builds sodium batteries around a novel solid electrolyte, engineered to make battery packs smaller, lighter, safer and more cost-effective than conventional lithium-ion systems. Its packs are designed for micromobility applications, including e-bikes, e-scooters and mopeds, with swappable formats aimed at both consumers and fleet operators. The company is scaling up production in Cambridge, UK, manufacturing both pouch and cylindrical cells and assembling them into e-bike battery packs.

Under the collaboration, TaiSan and SELANA will assess technical integration, safety, range, charging behaviour, lifecycle costs and potential pilot opportunities. The goal is to understand how advanced sodium chemistry can support SELANA's product roadmap and deliver a better experience for riders, dealers and urban mobility customers.

Supporting SELANA's UK expansion

SELANA is planning its entry into the UK market, where demand for safe, compliant and practical urban electric mobility continues to grow. The collaboration with TaiSan creates an opportunity to explore battery technology that could strengthen SELANA's UK product proposition, dealer network and future mobility services.

By working with a UK-based battery innovator, SELANA aims to combine Dutch urban-mobility expertise with British deep-tech innovation. The companies will explore how sodium batteries could support locally relevant requirements around performance, safety, sustainability and total cost of ownership.

"Micromobility needs batteries that are not only powerful, but safe, affordable and practical at scale," said Sanzhar Taizhan, CEO of TaiSan. "SELANA has a strong understanding of riders, dealers and the realities of urban mobility. As the company looks toward the UK market, we see exciting potential to explore how next-generation sodium technology can move from advanced battery development into real-world products."

"Battery innovation is central to the future of electric mobility," said Chingiskhan Kazakhstan, CEO of SELANA. "We are excited to work with TaiSan to explore what sodium batteries could mean for our customers, our planned UK expansion and safer, more sustainable cities."

Why sodium matters

Sodium is abundant and widely available, offering a route to reduce dependence on critical battery materials such as lithium, nickel and cobalt. For urban mobility, sodium-based systems also present compelling potential around safety, cost stability and performance in colder conditions.

TaiSan's solid-electrolyte approach combines earth-abundant materials with high energy density and improved safety, while targeting compatibility with existing micromobility form factors. The company positions its technology as a potential drop-in upgrade for e-bikes and scooters currently using lithium-ion or lead-acid batteries.

What happens next

The collaboration will begin with a joint technical and commercial exploration phase. TaiSan and SELANA will define evaluation criteria and assess opportunities for prototype testing, pilot deployments and future product integration.

The partnership reinforces TaiSan's mission to bring safer, more sustainable and commercially viable sodium-battery technology into everyday mobility - starting with the vehicles people use every day to move through cities.
