Abstract: So long as Li-ion batteries (LIBs) have their difficulties, the demand to improve "beyond-lithium" batteries goes beyond the factors of safety and sustainability. With the pressure for renewable energy resources and the enchantingly digitalized current lifestyle, the need for batteries will augment. Therefore, in this article, it has been evaluated the promising alternative alkali metals of "sodium-ion and potassium-ion" batteries. A vast study on H-capture by LiNa[GeO--SiO], LiK[GeO--SiO], LiNa[SnO--SiO], and LiK[SnO--SiO] was carried out including using "DFT" computations at the "CAM--B3LYP--D3/6-311+G(d,p)" level of theory. The hypothesis of the hydrogen adsorption phenomenon was figured out by density distributions of "charge density differences (CDD), total density of states/overlap population density of states (TDOS/OPDOS) and Localized orbital locator (LOL)" for nanoclusters of LiNa[GeO--SiO]--2H2, LiK[GeO--SiO]--2H2, LiNa[SnO--SiO]--2H2, and LiK[SnO--SiO]--2H2. The oscillation in charge density amounts displays that the electronic densities were mainly placed in the edge of "adsorbate/adsorbent" atoms during the adsorption status. As the benefits of "lithium, sodium or potassium" over "Ge, Sn/Si" possess its higher electron and "hole motion", permitting "lithium, sodium or potassium" devices to operate at higher frequencies than "Ge, Sn/Si" devices. Among these, "sodium-ion" batteries seem to demonstrate the most agreement in terms of primary competence.
