Perovskites are gaining attention as anode materials in lithium-ion battery research due to their advantageous crystal structure and tunable properties. The perovskite lattice, with a general formula of ABX3, provides a flexible and stable framework that allows for effective lithium-ion diffusion and enhanced charge storage capacity. Compared to traditional anode materials, perovskites offer high ionic conductivity and good thermal stability, making them suitable for high-performance battery applications. By allowing for various chemical substitutions within the structure, perovskites can be customized to optimize conductivity and specific electrochemical properties, leading to improved energy density and cycle stability in batteries. These characteristics give perovskites an edge in applications where battery longevity and high energy output are critical.
However, perovskites also present challenges, particularly in their sensitivity to environmental factors and common solvents used in electrode preparation. Many perovskite materials are susceptible to degradation when exposed to moisture or polar solvents, which can compromise the stability and performance of the anode. Water and solvents like N-methyl-2-pyrrolidone (NMP), often used in battery electrode fabrication, can lead to structural breakdown in perovskites, impacting their ionic conductivity and decreasing battery efficiency.
In order to counter these issues, in this work, we are investigating the application of a dry anode process in order to create CsPbBr3 based anodes.
