Scientists cook up a green recipe for recycling lithium-ion batteries using vegetable oil.
Research led by Professor Andy Abbott and Dr. Jake Yang at the University of Leicester working under the Faraday Institution’s ReLiB project found an innovative way of recovering valuable battery-grade metal oxides from crushed batteries by using nanoemulsions created from a trace of cooking oil in water. The study is published in the journal RSC Sustainability.
From everyday experience, we know oil and water do not mix unless we add soap, but research has shown that using ultrasound can create nano-droplets of oil that are stable for weeks. Crucially, oil nano-droplets are found to purify battery waste, commonly known as “black mass,” as it contains a mixture of carbon (graphite) and valuable lithium, nickel and cobalt metal oxides (NMC).
The oil nano-droplets stick to the surface of the carbon, acting as a “glue” to bind hydrophobic graphite particles together to form large oil-graphite conglomerates which float on water, leaving the valuable and hydrophilic lithium metal oxides untouched. The oil-graphite conglomerate can simply be skimmed off, leaving pure metal oxides.
Current recycling techniques use a combination of furnace heat treatment to burn off the undesired graphite, thereby increasing the CO2 footprint of the EV value chain, as well as concentrated corrosive acids which take valuable battery-grade metal oxides all the way back to the lower-valued battery precursor materials from which the battery was first made.
The Leicester-developed emulsion technique allows short-loop recycling of lithium-ion batteries. The battery-grade crystalline structure of the recovered material is not destroyed in this process and allows the remanufacturing of the recovered material directly back into new battery cells, unlike pyro/hydrometallurgical methods. This could potentially make the battery supply chain more sustainable and cheaper.
Dr. Jake Yang from the University of Leicester School of Chemistry said, “This quick, simple and inexpensive method could revolutionize how batteries are recycled at scale. We now hope to work with a variety of stakeholders to scale up this technology and create a circular economy for lithium-ion batteries.”
The Electric Revolution comes with drawbacks—one being challenges around how we efficiently and sustainably recycle large volumes of batteries at the end of their working life.
The use of batteries for electric vehicles and energy storage is only a sustainable future if the recycling pathway is green and cost-efficient. Globally, there are an estimated 40 million electric vehicles (EVs), and there are approximately 10 billion active mobile phones, laptops and tablets worldwide, all powered by lithium-ion batteries. However, the lack of regulations means lithium-ion battery packs are not designed to be recycled.
The Universities of Leicester and Birmingham are also collaborating to bring together several technologies developed under ReLiB in an InnovateUK project, ReBlend. This is creating a pilot line capable of processing 10s of kg/h of black mass to demonstrate that this short loop reprocessing can function economically to provide battery grade material for new cells.
“The ReLiB project is one of the Faraday Institution’s flagship projects developing innovative technology to capture value and retain scarce resources in the circular economy of battery manufacture and recycling. This work offers a promising route for short-loop recycling of lithium-ion batteries at scale,” commented Professor Martin Freer, CEO of the Faraday Institution.

A world-first technology has been developed by introducing a roll-to-roll compatible flash process into secondary battery electrode manufacturing, significantly suppressing the performance degradation of thick electrodes.
The research is published in the journal Small Methods. The findings present a new possibility of reducing battery costs by minimizing inactive materials and simplifying the manufacturing process while increasing energy density and capacity, making batteries smaller and lighter.
The Korea Institute of Machinery and Materials (KIMM) has developed an electrode activation technology utilizing an ultra-fast, large-area flash process to mitigate thick electrode degradation. Using the pilot-scale test bed, its compatibility with roll-to-roll (R2R) processes was successfully demonstrated.
Thick electrodes offer advantages such as high energy density, fewer battery pack layers, a simplified structure, and increased manufacturing efficiency, leading to a drastic reduction in production costs.
However, thick electrodes also face challenges, including increased resistance to lithium-ion and electron transport and limited electrolyte penetration, which lead to decreased overall electrochemical performance such as rate capability.
To address these issues, the research team introduced a flashlight irradiation process on thick electrodes for an instantaneous duration of less than one millisecond. The photothermal reaction triggered by this process instantly induces changes such as binder carbonization, interlayer expansion of active material (graphite), increased porosity, and an enlarged electrode-electrolyte interfacial area.
These chemical and structural modifications enhance lithium-ion and electron transport while improving electrolyte penetration, ultimately suppressing the performance degradation of thick electrodes.
By utilizing surface photothermal reactions, this technology prevents the entire thick electrode, including the current collector, from prolonged high-temperature exposure. This minimizes binder decomposition, preserving mechanical durability while also preventing oxidation-related thermal damage to the current collector.
This technology is highly compatible with standard roll-to-roll manufacturing processes and is expected to be expandable to various electrode materials, including nickel-cobalt-manganese (NCM) cathodes.
Furthermore, the research team of KIMM is applying and evaluating the flash process in the electrode drying stage. It has been confirmed that the technology can significantly reduce the energy consumption and processing time required for electrode drying while simultaneously inducing electrode activation effects.
Recently, in collaboration with lithium-ion battery equipment manufacturers, the team has been developing mass-production-scale facilities and conducting process evaluations.
The principal researcher, Dr. Kyoohee Woo of KIMM stated that since flash-based electrode activation technology is a post-treatment process compatible with roll-to-roll manufacturing, it can be easily integrated into existing production lines and facilities.
Moving forward, the team aims to enhance the technology’s maturity and continue testing and validation to facilitate its adoption by domestic lithium-ion battery manufacturers.

Electric vehicles (EVs) are revolutionizing the way we get around, but did you know that the heart of these vehicles—lithium-ion batteries—is heavily reliant on China’s supply chain? According to BloombergNEF, China currently dominates 77% of global EV battery production capacity, while the U.S. lags behind at just 14%. This dependency not only poses risks to supply chain security but could also drive up EV prices and hinder market competitiveness. Breaking free from China’s grip has become a critical step for U.S. electric vehicle battery production, and HIMAX Electronics is playing a pivotal role by offering high-performance battery solutions. In this article, we’ll dive deep into the state of battery manufacturing, the importance of reducing reliance on China, and how to choose the right battery supplier to add value to your business.
The Current State of the U.S. EV Battery Supply Chain: Why Are We So Dependent on China?
China’s battery manufacturing capacity reigns supreme globally, thanks to its economies of scale, control over raw materials, and low-cost production capabilities. According to the latest 2025 data, China produces 90% of the world’s graphite—a key raw material for lithium-ion battery anodes—and boasts over 300 gigawatt-hours of battery production capacity. This dominance leaves U.S. EV manufacturers heavily reliant on China, especially for lithium-ion battery production. Whether it’s Tesla, General Motors, or Ford, parts of these iconic brands’ battery components inevitably come from Chinese supply chains.
However, this dependency comes with significant risks. First, supply chain disruptions could lead to battery shortages, directly inflating EV prices. For instance, geopolitical tensions in 2022 caused fluctuations in battery raw material prices, impacting the stability of the U.S. EV market. Second, relying on China may stifle U.S. innovation and competitiveness, particularly in cutting-edge battery technologies. Geopolitical uncertainties further compound the issue—trade restrictions or export bans could leave U.S. EV manufacturers scrambling to secure batteries. Breaking free from China’s grip isn’t just about supply chain security; it’s about securing the future of the U.S. EV industry.
How to Break Free from China’s Grip: The Rise of U.S. Battery Manufacturing
To reduce dependence on China, the U.S. government has rolled out a series of supportive policies, with the Inflation Reduction Act (IRA) being the most significant.
