Discovering halide superionic conductors for catholyte
Project by Professor Gerbrand Ceder

Professor Gerbrand Ceder has been making significant strides in the field of lithium transport and superionic conductors. In his latest research paper, “Effect of Cation Disorder on Lithium Transport in Halide Superionic Conductors,” Professor Ceder explores how cation disorder affects the transport of lithium ions in halide-based superionic conductors.
The study is particularly relevant in the context of battery technology, as it has significant implications for the development of more sustainable and reliable batteries. Lithium-ion batteries are used in a wide range of applications, including electric vehicles, portable electronics, and renewable energy storage systems. However, they are prone to several issues such as thermal runaway, safety concerns, and limited cycle life.
Halide-based superionic conductors are promising candidates for next-generation lithium-ion batteries due to their high electrical conductivity and stability. Professor Ceder’s research provides valuable insights into how cation disorder can affect the transport of lithium ions in these materials, which is crucial for optimizing their performance and safety.
One of the key findings of the study was that cation disorder can cause a reduction in the transport of lithium ions in halide-based superionic conductors. This is due to the formation of ion traps and barriers that hinder the movement of the ions through the material. However, Professor Ceder also found that it is possible to mitigate this effect by introducing defects or doping elements into the material.
Another important aspect of Professor Ceder’s work is the complementarity between computational and experimental approaches. The study combines theoretical calculations with experimental measurements to provide a comprehensive understanding of the transport mechanisms in halide-based superionic conductors. This approach allows for the identification of key factors that affect the transport of lithium ions and enables the development of more efficient and effective materials.
As we continue to transition towards a low-carbon economy, it is essential that we invest in research and development that addresses the challenges posed by battery technology. Professor Ceder’s work provides valuable insights into how we can optimize the performance and safety of lithium-ion batteries, which is crucial for achieving our sustainability goals.
