Lithium-ion (Li-ion) batteries occupy centre-stage among modern energy storage technologies, due to their high energy and power capacities, with low relative volume and weight. Li-ion batteries are projected to play a key role in global decarbonisation of energy – as energy storage devices for hybrid and electric vehicles, and in combination with renewable energy sources for grid energy storage.
As the UK transitions to the use of renewable energy, the long-term environmental sustainability and international competitiveness of many industrial sectors – especially the automotive industry – will depend on robust and precise measurement techniques for Li-ion batteries. Emerging energy storage technologies, such as sodium-ion batteries, supercapacitors and all-solid-state lithium-ion batteries, depend equally on accurate measurement for their rapid development. Our recent Energy Transition Report summarised essential measurement requirements of the UK battery industry.
In parallel to the £274m government investment in battery research from the Faraday Battery Challenge, NPL is combining expertise from multiple scientific disciplines to develop metrology for high energy density batteries. Our work will underpin new developments in battery science, encompassing support to industrial development of materials and devices as well as protocols to guide measurements in fundamental academic research.
