138 This is quite significant compared with bare ion insertion ( e.g. ∼10% for Li + and ∼50% for K + ). 100,136 Expansion of the actual composite electrode tends to be a bit smaller, 144 but this factor is expected to become problematic at the battery level. 145 Furthermore, such expansion leads to a decrease in the volumetric capacity/energy density of the system.
