Ampcera and LLNL awarded $1.5 million to 3D print lithium batteries
The U.S. Department of Energy (DOE) awarded $1.5 million to Ampcera and Lawrence Livermore National Laboratory (LLNL) to develop a safer lithium battery with higher power and energy densities using a low cost, high throughput dry additive manufacturing process.
The joint project between LLNL and Ampcera is one of six energy systems projects selected for an award from the DOE’s Office of Advanced Manufacturing to reduce industrial emissions and manufacture clean energy technologies.
The proposed dry additive manufacturing technology is highly energy efficient – with >10 times the throughput of conventional slurry-based processing – reducing lithium battery manufacturing costs by 50% or more.
“The environmentally friendly process allows for the processing of thick, high-capacity 3D cathode structures, allowing lithium-ion batteries to reach the fast charge goal of 80% charge in 15 minutes or less,” said senior scientist and researcher Jianchao Ye. of the LLNL.
As an innovator in the development and manufacture of advanced materials for solid-state batteries, Ampcera has a vested interest in this project. In addition to developing structured cathodes for lithium-ion batteries, Ampcera also plans to further develop this technology for manufacturing solid-state batteries.
“The partnership between LLNL and Ampcera will accelerate the development and commercialization of ultra-fast, low-cost additive manufacturing technology for manufacturing high-performance lithium batteries. After developing 3D-structured cathodes, we plan to extend the technology to anode design and further explore its application in solid-state Li metal batteries with even higher energy and power densities. said co-researcher Hui Du, chief technology officer. and co-founder of Ampcera.
“Ampcera is supporting this project because we believe it has the potential to revolutionize the large-scale manufacturing of solid-state batteries with intrinsic safety, high energy density > 450 Wh/kg, and low cost of
