Carbon fiber-based batteries, integrating energy storage with structural functionality, are emerging as a key innovation in the transition toward energy sustainability.
Here, an all-carbon fiber-based structural battery is demonstrated utilizing the pristine carbon fiber as negative electrode, lithium iron phosphate (LFP)-coated carbon fiber as positive electrode, and a thin cellulose separator. All components are embedded in structural battery electrolyte and cured to provide rigidity to the battery.
Building on the trailblazing carbon-fiber-as-a-battery work started at Sweden's Chalmers University of Technology, deep-tech startup Sinonus is working to commercialize a groundbreaking new breed of multifunctional carbon fiber.
In a 2018 CTU study, researchers found that carbon fiber-based structural batteries could significantly reduce the weight of vehicles and aircraft. In 2021, they achieved a significant milestone by announcing a structural battery with ten times the performance of previous versions.
Researchers at Chalmers, in collaboration with Carbon Nexus at Deakin University, have shown how the manufacturing process can tailor carbon fiber's multifunctional properties. An important step in the development of structural batteries.
Increased international collaboration will be vital in accelerating technological progress and addressing existing challenges. As the field matures, carbon fiber-based batteries hold significant promise for advancing sustainable energy systems and contributing to a decarbonized future.
Sinonus CEO Markus Zetterström stated they have developed an innovative carbon fiber composite that doubles as a battery. “By substituting part of the structural material in various applications with our multipurpose composite, it is possible to increase electrical storage capacity without adding weight or volume,” he explained.

The national electric utility of Senegal, Senelec, has signed a 20-year CCA with Infinity Power for a battery energy storage project.
Infinity Power, a joint venture between Egypt's Infinity and UAE's Masdar, has sealed a 20-year capacity change agreement related to a 40-MW/160-MWh battery energy storage systems (BESS) project with Senegal's national electricity company Senelec. Infinity Power will build the battery at the Tobene substation in the city of Thies.
The planned facility, described as one of the largest of its kind in West Africa, will help Senelec stabilise the country's electricity grid and pave the way for further renewable energy growth in Senegal.
Cairo, Egypt and Abu Dhabi, UAE - 13 November 2023: Infinity Power, a joint venture between Egypt's Infinity and UAE's Masdar, announced today the signing of a 20-year Capacity Change Agreement with Senelec, Senegal's national electricity company to supply 40MW through a battery energy storage system (BESS).
Expected to be one of the lowest cost producers of electricity in Senegal, the project is helping reduce the cost of electricity generation in the country, which has one of the highest generation costs in Sub-Saharan Africa. Infinity Power is Africa's largest pure play renewable energy provider.
The battery system is expected to provide ancillary services in power transmission and reduce the local grid's dependence on thermal power plants. According to news reports, Senelec is said to have estimated that the BESS will save the grid US$165 million over its operating lifetime.
In 2023, skipping battery actions increased balancing costs by £24 million. This is calculated by the total cost of the actual dispatches in the Balancing Mechanism minus the cost of the cheaper battery alternative. 9 million occurred in October 2023, closely followed by December 2023.
Battery balancing can be accomplished using two main methods: passive balancing and active balancing. Passive balancing relies on resistors to discharge excess charge from high-voltage cells, while BMS active balancing uses sophisticated components like transformers, inductors, or capacitors to transfer energy between cells.
One of the most important parameters of estimation the performance of battery cell balancing is the equalization time. Other parameters such as power efficiency and loss are related to the balancing speed.
Other risks associated with heat causing the battery to overheat or even get out of control known as thermal runaway. To counteract these challenges, EV manufacturers practice battery balancing to guarantee that all the cells within a pack are working at their given voltage, as well as charge levels.
The research delved into the characteristics of active and passive cell balancing processes, providing a comprehensive analysis of different cell balancing methodologies and their effectiveness in optimizing battery efficiency.
This article has conducted a thorough review of battery cell balancing methods which is essential for EV operation to improve the battery lifespan, increasing driving range and manage safety issues. A brief review on classification based on energy handling methods and control variables is also discussed.
Individual cell voltage stress has been reduced. This study presented a simple battery balancing scheme in which each cell requires only one switch and one inductor winding. Increase the overall reliability and safety of the individual cells. 6.1.
