Furthermore, by adjusting the amount or type of specific components, the slurry formulation can be adapted from industrial battery cell production 133. The 3D-printed batteries’ energy density can be increased by depositing an active material in the z -direction while the cell’s power density remains constant.
“Lithium metal anode batteries are considered the holy grail of batteries because they have ten times the capacity of commercial graphite anodes and could drastically increase the driving distance of electric vehicles,” said Xin Li, Associate Professor of Materials Science at SEAS and senior author of the paper.
Dr Nuria Tapia-Ruiz, who leads a team of battery researchers at the chemistry department at Imperial College London, said any material with reduced amounts of lithium and good energy storage capabilities are "the holy grail" in the lithium-ion battery industry.
Kanazawa and coworkers recently prepared thin-film batteries consisting of amorphous vanadium oxide with lithium phosphorus oxide (VO-LiPO), Si, and LiPON as cathode, anode, and electrolyte materials, respectively 102.
The research not only describes a new way to make solid state batteries with a lithium metal anode but also offers new understanding into the materials used for these potentially revolutionary batteries. The research is published in Nature Materials.
"AI and supercomputing will become crucial tools for battery researchers in the upcoming years to help predict new high-performing materials," she said. But Dr Edward Brightman, lecturer in chemical engineering at the University of Strathclyde, said the tech would need to be "treated with a bit of caution".
