Technical FAQs 4

Can graphite be intercalated into a potassium ion battery?

Graphite is one of the most widely used anode materials in potassium-ion batteries (PIBs). However, the exact mechanism of K + ions intercalation into graphite has not yet been fully understood. In addition, the intercalation process strongly depends on the selection of the electrolyte system.

Are potassium ion batteries a viable alternative to lithium ionic batteries?

Potassium-ion batteries (PIBs) are currently considered as a promising alternative to lithium-ion and sodium-ion batteries (LIBs and SIBs) [, , ].

What is a potassium based dual ion battery?

Traditional potassium (K)-based dual ion batteries use electrolytes with concentrations below 1 m (mol kg −1), which exhibit a comparatively low oxidation potential of ∼4.4 V versus K/K +. This limits the operational longevity and energy density of the batteries.

Are K-graphite anode half batteries good?

In contrast, the half batteries with lower-concentration electrolytes exhibit significantly poorer rate performances (Fig. 2 f, S8c and S8d). It is evident that the K-graphite anode half batteries, utilizing a 10.0 m KFSI/EC:DMC high concentration electrolyte, demonstrate exceptionally excellent performance.
