Typical Li intercalation electrodes are well ordered materials in which lithium ions cycle in and out. Dimensional changes in these compounds often reduce the mobility of ions to the point whereby no more Li can be extracted. We recently developed cation-disordered materials as a novel concept for Li-storage materials. Using percolation theory we show that despite their disorder these materials can have excellent Li mobility and significantly larger capacity than classical electrode materials. I will discuss the thermodynamic and kinetic models needed to better understand these materials.
