Atomic Layer Deposition (ALD) for Lithium-ion Battery Components

Abstract

The demand for high-performance and long-lasting Li-ion batteries has increased significantly due to the growing use of portable electronic devices, electric vehicles, and renewable energy storage systems. However, the performance and stability of Li-ion batteries are still limited by various factors, including parasitic reactions, electrode degradation, and unstable electrolytes. Therefore, the development of novel materials and techniques to improve the performance and stability of Li-ion batteries is essential. In recent years, Atomic Layer Deposition (ALD) has emerged as a promising technique for the deposition of thin and uniform coatings on various components of Li-ion batteries to enhance their electrochemical properties and stability. This study investigates the use of Atomic Layer Deposition (ALD) for the deposition of thin and uniform coatings on various components of Li-ion batteries. The results indicate that ALD can be used to deposit coatings on electrodes and separators to improve the stability and performance of the electrolyte by reducing parasitic reactions. Additionally, ALD coatings on cathode and anode materials have been shown to improve their electrochemical properties, including cycling stability and rate capability. ALD coatings on solid electrolytes also enhance their ionic conductivity and stability. Furthermore, ALD coatings on current collectors improve their stability and reduce their resistance.
