LiCAP Technologies, Inc. has expanded a portfolio of technologies compatible with the proprietary Activated Dry ElectrodeTM process, unveiling a cost-effective and sustainable pathway for commercialization of the solid-state battery.
Solid-state battery (SSB) technology holds the promise of improved safety, increased specific energy, and energy density over conventional lithium-ion batteries (LIB). However, the traditional “wet” coating approaches to electrode manufacturing used in the commercial production of LIBs are not compatible with the dry room processing of moisture-sensitive solid-state electrolyte materials.
LiCAP successfully applied the Activated Dry ElectrodeTM technology to the manufacturing of solid-state battery electrodes and produced the first catholyte samples. Since the start of the trials in February 2022, LiCAP developed several SSB electrode formulations with NMC and sulfide-based electrolyte materials. These materials were processed into stand-alone active layer films and laminated on aluminum current collectors. At the current development stage, LiCAP can manufacture SSB electrode samples with the areal mass loading ranging between 26-60 mg/cm2 with high electronic conductivity. Moreover, LiCAP’s engineering team determined that the developed SSB electrodes can be scaled-up to a pilot and large-scale production similar to the already existing lines for lithium-ion battery and ultracapacitor electrodes.
“The wet coating process is proven in the lithium-ion battery industry, but its compatibility with SSB is limited and the economics are flawed,” said Dr. Linda Zhong, the president of LiCAP. “Activated Dry ElectrodeTM technology can address the shortcomings of traditional slurry coating. We are working on a breakthrough solution, which would open the automotive industry up to the next generation battery. Our pre-production line will produce SSB electrodes at a 60 m/min speed and will be commissioned in 2023.”
“Our Activated Dry ElectrodeTM process will help the solid-state battery industry to achieve performance, low-cost targets and, ultimately, pave the path to commercialization,” said Dr. Katharina Gerber, Director of Business Development for LiCAP. “Our pilot equipment is now available for feasibility projects on customer’s SSB materials at our facility located in Sacramento, CA.“
