High capacity negative electrode materials for potassium-ion batteries

Abstract

The talk will discuss possible high capacity negative electrode materials for potassium-ion batteries. This new type of high voltage batteries currently attracts significant attention as an alternative to lithium-ion batteries due to the abundance of potassium in nature and its relatively homogeneous distribution globally. Identification of possible electrode materials for these new batteries is therefore a key task. Selected negative electrode materials operating via alloying, conversion and conversion-alloying mechanisms and capable of significantly exceeding the capacity of graphite will be discussed in this talk.
