ALD is the superior technique for this application due to the possibility of conformal coatings with enormous aspect ratios.
Here, we want to give a brief insight into oxide-based coatings applied by atomic layer deposition (ALD) 2.Ĭoating cathode-powder materials is a challenging task. However, plenty of functional coatings are available and all of these behave differently on different cathode materials demanding a vast amount of research. Additives to the electrolyte may enhance the lifespan but functional coatings of the cathode material show a more promising path 1. More severe is the degradation of cathode material due to the reaction with the electrolyte. Plenty of cathode materials emerged to bring down the cost by switching to more earth-abundant elements, such as Mn or Fe. ChallengesĬommonly, cathodes are composed of expensive elements such as Co and tend to react with the electrolyte. Features of LIBs include among others a high power density, comparable long lifetime, and high charge/discharge rates. The cathode is the critical part of LIBs determining the cell performance and overall cost.
Intensive research is performed by industry and government to build an energy-sustainable economy.
#Li ion battery cathode materials portable
Lithium-ion batteries (LIBs) are dominating the market, especially for electric vehicles and portable devices. To conquer the global energy transition towards renewable energy sources reliable energy storage is required.
