The drying of the wet particulate electrode coating is a crucial stage in the production of electrodes for lithium-ion batteries.
A porous film is created when the solvent evaporates, solidifying the electrode film. Coating and drying were done on anode slurries made of graphite and an aqueous binder system.
An impingement drier and a substrate carrier with a temperature control were employed in a lab setup to ensure specified and controllable drying conditions.
The selection of experimental temperatures was based on a computation of steady-state temperatures that arise from gas temperatures that are frequently used in industrial drying processes. This was done to allow a scale-up to continually passing dryers.
The Global Lithium-ion dry electrode market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The Series A financing for AM Batteries (AMB), a leader in lithium-ion dry-electrode technology, has closed.
The oversubscribed Series A funding for AMB was led by Anzu Partners, an investment company that specialises in cutting-edge industrial technologies, and included TDK Ventures, Foothill Ventures, Toyota Ventures, Zeon Ventures, SAIC Capital, VinFast, Doral Energy-Tech Ventures, and Creative Ventures.
As a result of the funding, AMB will be able to grow its team, quicken the commercialization process, convert its roll-to-roll manufacturing pilot line into a customer-facing production line, and expand its dry-electrode manufacturing platform to accommodate new battery chemistries and technologies, such as solid-state batteries.
To enhance the manufacturing of lithium-ion cells, a new electrode drying procedure. The EPIC project, which aims to enhance the electrode drying process for lithium-ion batteries, has received an investment from the German Federal Ministry of Research.
By expediting the lithium-ion battery electrode drying process, the new EPIC project, led by Karlsruhe Institute of Technology (KIT), aims to lower the cost of battery manufacturing.
During discharge, lithium ions move through the electrolyte from the negative electrode (anode) to the positive electrode (cathode), producing an electric current.
With MOISTURE, WATER, or STEAM, lithium reacts aggressively to produce heat, flammable and explosive hydrogen gas, and poisonous lithium oxide.
The electrode layers that are employed for energy storage determine the performance of lithium-based battery cells.
Producing electrodes requires a lot of energy and might take a long time, which raises the cost of production. Now, the Thin Film Technology (TFT) group at KIT has created a novel coating method that allows for the fast production of lithium-ion battery electrodes.
Professor head of TFT: “It is vital to analyse the different process phases collectively and to take interactions into consideration.”
The project’s overall goal is to cut the cost of drying the electrodes for batteries by at least 20%. While preserving the electrodes’ quality and long-term stability, scientists from the EPIC project want to speed up drying by at least 50%.
The faster coating speeds are especially appealing when drying times can be shortened without having to lengthen the pricey drying line. Prior to electrolyte filling, KIT will investigate drying directly in the cell stack and adjusting the necessary cell moisture.
A joint investigation between KIT and Technical University of Braunschweig researchers will assess how drying intensity and duration affect cell characteristics.
Recommendations for scaling up the process to an industrial level will be given after the project partners have evaluated the various production methods using appropriate process-cost models.
The Post Lithium Storage (POLiS) cluster of excellence, where KIT will work with Ulm University and ZSW to build future batteries, will immediately incorporate the most recent advancements in production technology.
