Faradion Limited is a British company specializing in sodium-ion battery technology, established in 2011 by Dr. Jerry Barker, Dr. Chris Wright, and Ashwin Kumaraswamy. The company has developed innovative non-aqueous sodium-ion cell technology that offers performance comparable to lithium-ion batteries but at significantly lower costs. This technology presents a sustainable solution for various applications, including transportation, stationary energy storage, backup power systems, and remote energy provision. Faradion’s approach addresses growing concerns about lithium resource limitations and the environmental impact of traditional battery production.

Battery Technology

Faradion’s sodium-ion battery technology represents a significant advancement in energy storage solutions. The company’s patented chemistry eliminates the need for expensive materials like cobalt and copper, instead utilizing abundant sodium resources. Their non-aqueous sodium-ion cells feature a unique zero-volt capability, ensuring safe transportation and maintenance.

The technology delivers excellent energy density across a wide temperature range, making it suitable for diverse applications. In transportation, these batteries serve as effective replacements for lead-acid batteries in electric vehicles, e-scooters, and e-bikes, providing enhanced range and carrying capacity. For stationary storage, the batteries offer reliable performance while maintaining cost advantages over traditional options.

A distinctive feature of Faradion’s batteries is their safety profile. The sodium-ion chemistry inherently reduces risks associated with thermal runaway, a common concern with lithium-ion batteries. This enhanced safety, combined with the use of readily available materials, positions the technology as a practical solution for large-scale energy storage needs.

Recent Projects

In October 2024, Reliance New Energy Limited completed the acquisition of the remaining 8% stake in Faradion, achieving full ownership. This acquisition integrates Faradion’s technology into Reliance’s planned energy storage gigafactory in Jamnagar, India. The project aims to establish large-scale production of sodium-ion batteries, supporting India’s renewable energy initiatives and electric vehicle market development.

Investors

Faradion’s primary investor is Reliance New Energy Limited, which acquired the company for £100 million in 2021, with an additional £25 million invested as growth capital. Previous investors included Mercia Technologies PLC, which led a £3.2 million investment round in 2017, Finance Yorkshire Seedcorn Fund, and Haldor Topsoe A/S. These investments supported Faradion’s research, development, and commercialization efforts.
