Greece-based Pleione Energy has been working with ESA on a project to industrialize the production of Li-Ion battery electrodes, which integrate graphene as their main active material, and produce ten meters at a time.
These negative electrodes were used for Li-Ion battery cells, which were produced and tested according to the European Cooperation for Space Standardization, ECSS, Standards, representing space-ready quality.
“The challenge was the scale of laboratory activities on industrial production, with the potential to make kilometers of electrodes simultaneously,” commented ESA materials specialist Ugo Lafont.
“Our bread cell exhibits good properties, produces 12.5 Ah of energy, offers a European way to improve battery capacity and improve key electrochemical characteristics. In particular, the nano-size of graphene guarantees enhanced mobility of lithium ions at the heart of the system, which leads to an improved capacity for the same amount of material and higher charging and discharging rates without degrading the system.The potential is there for new cheap but reliable batteries suitable for small satellites and CubeSats in particular.
Athanasios Masouras of Pleione Energy notes: “Once the battery cells have been sealed and integrated into a battery pack, the real test came as we subjected it to the temperature profile of a typical low-Earth orbit mission, which means frequent changes in high temperatures. Sunlight to cold darkness.But our tests confirm that we have been able to increase the specific capacity of the anode of the battery compared to traditional graphite, and to develop electrodes that maintain their performance in high current densities – so They are suitable for fast charging / discharging applications. Overall, graphene offers about 20% higher specific capacity than graphite, while its endurance of higher current densities should mean longer cycle life for batteries, safer operation due to lower temperature and overall material consumption , and therefore costs.
The cost-effective Graphene Energy Storage project, COORAGE, was developed by Pleione Energy and the German Fraunhofer Institute for Silicate Research to develop an end-to-end industrial process for electrode production, with Omnidea-RTG in Germany for the breadboard battery cells of Design project.
“The process itself is not revolutionary,” Ugo added. “The right step forward is in the way graphene is added. Electrodes always need a metallic current collector that collects the current and connects it to external circuits. These positive and negative collectors have active materials attached to them that are in the. Forms of powder come in such a way that they have to be laminated and glued to their current collector – like making the flour and pancake dough that you use to cook it, so this powder is transformed into a mud to be painted on the current collector , binding it in place for intimate contact that flows electrons.But in the past this process used expensive and highly toxic solvents.We converted to water as a solvent mixed with cellulose nanocrystals taken from plant biomass, which is hundreds of times more It also involves some proprietary knowledge, such as the ability of a chef to make your meal taste good!
Athanasios adds: “As well as reducing the overall environmental impact of the process, the removal of these solvents – which are expensive to both buy and use – significantly reduces manufacturing costs by about 20% and makes battery production more compliant with the strictest EU environmental standards. “
The COORAGE project, supported by ESA’s General Support Technology Program (GSTP), which prepares promising products for space and the market, also examines the payoff of graphene for Li-ion supercapacitors, which are power storage devices capable of short-circuiting high-speed bursts. they deliver. very high power.
“Our next step is to transfer our technology to cylindrically standardized cells, then increase its technology readiness level through extensive testing, with our ultimate goal of qualifying for space flight,” Athanasios notes.
“We are grateful for the opportunity to work with ESA, which was essential to achieving our goals. For small and medium-sized businesses, working with GSTP and similar ESA programs is a critical resource for technologies closer to the Bringing space by offering space thinking from the earliest stages of a project.
