Nyobolt secures $60 million in funding at a $1 billion valuation, with Symbotic leading the investment, aimed at developing ultrafast-charging batteries for warehouse robots and AI data centres.

      **Summary:** Cambridge-based battery startup Nyobolt has secured $60 million in funding, achieving a valuation of $1 billion, with Symbotic leading the investment. Symbotic's warehouse robots currently utilize Nyobolt's ultrafast-charging niobium tungsten oxide cells, which charge in less than five minutes and endure 20,000 cycles. These batteries are designed for physical AI and power systems in data centers rather than for electric vehicles.

      The revolutionary battery that has elevated Nyobolt to unicorn status does not power vehicles; instead, it powers warehouse robots. On Tuesday, Nyobolt announced it completed a $60 million Series C funding round, reaching a $1 billion valuation, led by Symbotic, a Nasdaq-listed robotics enterprise whose autonomous mobile robots already use Nyobolt’s technology. This funding round raises total investment to around $160 million and evaluates a company founded in 2019 based on research from the University of Cambridge led by Professor Dame Clare Grey. The batteries can charge from zero to 80% in under five minutes, last over 20,000 charge cycles without loss of performance, and boast 20 times the energy density of supercapacitors. Originally intended for electric vehicles, the technology has found its market in physical AI.

      **Technology Details:**

      Typical lithium-ion batteries use graphite anodes, limiting their charging speed as lithium ions can only move in and out at a controlled rate. Nyobolt's innovation features a niobium tungsten oxide anode that allows up to 100 times more lithium-ion mobility than graphite, facilitating rapid charging that could destroy conventional cells. The company enhances this anode chemistry with proprietary designs and integrated power electronics to manage the fast charging dynamics. Consequently, these batteries can be fully charged in mere seconds for smaller sizes and within five minutes for larger ones, boasting a cycle life of tens of thousands of charges rather than the hundreds typically seen in traditional lithium-ion batteries.

      The extended cycle life is crucial for Nyobolt's target markets. Solid-state batteries in development for future electric vehicles aim for high energy density and quick charging but are designed for occasional daily charging. In contrast, Nyobolt's batteries are made for applications requiring dozens or hundreds of charges daily: warehouse robots that recharge between tasks without long downtime, data center UPS systems needing rapid energy management during grid fluctuations, and autonomous machines operating nonstop in industrial settings. Nyobolt prioritizes power density over energy density, focusing on quick energy absorption and release.

      **Clientele:**

      Symbotic's choice to lead the funding round signifies Nyobolt's commercial appeal. Symbotic utilizes fleets of self-operating mobile robots in large distribution centers, particularly within Walmart's logistics network, implementing the technology in over 42 centers after acquiring Walmart’s Advanced Systems and Robotics division for $200 million in 2026. Walmart simultaneously invested $520 million in Symbotic, giving the company a backlog of over $5 billion. The SymBot robots previously utilized ultracapacitors, which charge quickly but have limited energy capacity. In contrast, Nyobolt’s battery provides six times the energy capacity while ensuring ultrafast charging to maintain operational uptime. In warehouses, where robot uptime correlates with throughput and revenue, the battery becomes a critical component in determining robot productivity.

      Nyobolt's revenue is soaring, increasing fivefold annually, attributed to a growing demand surge for physical AI applications and infrastructure in data centers. Cambridge's technology sector has recently produced unicorns at a rapid pace, with Nyobolt being the latest to reach the $1 billion valuation, emerging from a university spinout dedicated to advancing materials science and engineering. The company was co-founded by Grey, a leading battery researcher, and CEO Sai Shivareddy. Other investors in the Series C round include IQ Capital, Latitude, Scania Invest, and CBMM.

      **Market Outlook:**

      Nyobolt is expanding beyond warehouse robotics to target two additional markets that require high-power, high-cycle-life batteries. In AI data centers, the company is positioning its technology as a viable alternative to traditional lead-acid and lithium-ion UPS systems, which are tailored for infrequent use during outages rather than the rapid charge-discharge cycles arising from modern grid instabilities and renewable energy fluctuations. The International Energy Agency predicts that energy consumption in data centers will double by 2026, with power management infrastructure becoming increasingly vital. Recently, Nyobolt secured an agreement with Rajasthan, India, to provide over 100 megawatts of off-grid AI data center and power management systems, transitioning the company from a component supplier to an infrastructure provider.

      The pursuit of energy solutions to meet AI's power demands has attracted hundreds of startups competing against established battery makers, grid operators, and energy storage firms. Nyobolt's edge lies in its focus: instead of trying to compete with CATL or BYD concerning energy density for electric vehicles, it targets power density and cycle life crucial for machines requiring rapid charging.
