About us

Nyobolt is a Cambridge-based scale-up built on over a decade of battery research led by University of Cambridge scientist Professor Dame Clare Grey.

Our vision is to become the leader in high-power, integrated energy systems that enable mission-critical uptime. Our systems-level innovation, born from a decade of shared dedication between world-class technicians, scientists, and experts, is enabling us to redefine the energy storage industry.

We are not just building batteries. We are transforming industries and accelerating progress where high-power and high uptime are mission-critical. Our solutions define success for industries such as AI data centres, autonomous robotics, commercial and passenger EVs, grid infrastructure and heavy industrial fleets.

Our journey

In 2018, Professor Grey and her team solved a long-standing bottleneck in lithium-ion batteries, opening up breakthroughs in ultra-fast charging properties. Focused on material science advances in the anode, Professor Grey identified a family of niobium tungsten oxides as the ideal replacement for traditional materials used in energy-dense lithium-ion batteries. The structure of the niobium tungsten oxide allows a greater volume of lithium ions to enter and leave the anode, in a controlled manner, multiplying the charging speed of the battery.

In 2019 she and co-founder and CEO Dr. Sai Shivareddy launched Nyobolt to commercialise this new ultra-fast charging battery technology in a fully integrated technology solution. Dr Shivareddy is another highflier and three-time entrepreneur. He obtained his PhD from St John’s College, Cambridge, followed by a decade-long career working all along the battery value chain from mining to manufacturing, including partnering with Clare and Dyson in developing new concepts for high power energy storage technologies prior to forming Nyobolt.

Our founders

Prof. Clare Grey

Chief scientist and co-founder

Clare P. Grey, FRS, DBE is the Geoffrey-Moorhouse-Gibson and Royal Society Professor of Chemistry at Cambridge University. After receiving a BA and D. Phil. from Oxford University she was a post-doctoral fellow at Nijmegen and at DuPont CR&D. She joined the faculty at Stony Brook University in 1994, moving to Cambridge in 2009, maintaining an adjunct position at Stony Brook. She is currently the director of the EPSRC Centre for Advanced Materials for Integrated Energy Systems (CAM-IES).
Recent honours/awards include Honorary PhD Degrees from the Universities of Orleans (2012) and Lancaster (2013), the Royal Society Davy Award (2014), the RSC John Goodenough Award (2019), the Richard R. Ernst Prize in Magnetic Resonance (2020), the RS Hughes Award (2020) for contributions in the field of energy and the (2021) Körber European Science prize.
Her current research interests include the use of solid-state NMR and diffraction-based methods to determine structure-function relationships in materials for energy storage (batteries and supercapacitors) and conversion (fuel cells).
