Layered lithium cobalt oxide, a key component of lithium-ion batteries, has been synthesized at temperatures as low as 300°C and durations as short as 30 minutes.
Lithium ion batteries are the most commonly used type of battery in consumer electronics and electric vehicles. Lithium cobalt oxide is the compound used for the cathode in LIB for handheld electronics. Traditionally, the synthesis of this compound requires temperatures over 800°C and takes 10 to 20 hours to complete.
"By understanding the reaction pathway, we were able to identify the factors that promoted the crystal growth of layered LiCoO," Matsui said."Specifically, the presence of water molecules in the starting materials significantly improved crystallinity of the end product."at low temperatures under ambient pressure," concludes Matsui."Our development of this hydroflux process will enable energy saving measures in various ceramic production processes.
