There is a varying mass contribution of the different nanoconfined interlayer molecules in the three samples, which are not participating in the reversible charge storage process, namely 1.0 H2O, 1.5 PA, or 1.0 HDA. Normalizing the maximum reversible lithium storage capacities of the materials per tetratitanate can then be calculated as ca. 2.10 Li + for HTO, 2.95 Li + for HTO-PA, and 2.52 Li + for HTO-HDA. This demonstrates that the maximum reversible ion storage capacity per transition metal is increased in interlayer-expanded, organically pillared HTO materials. At increasing GCD rates, the performance of HTO-PA remains superior compared to HTO and HTO-HDA. This indicates superior charge storage kinetics when using the layer separating/non-cross-linking PA pillars compared to cross-linking HDA pillars.
