Abstract
The aqueous sodium-ion battery is a promising alternative to the well-known lithium-ion battery owing to the large abundance of sodium ion resources. Although it is safer than the lithium-ion battery, the voltage window of the sodium-ion battery is narrower than that of the lithium-ion battery, thus limiting its practical implementation. Therefore, a highly concentrated electrolyte is required to address this issue. In the present work, the effect of the salt concentration on the transport properties of water molecules is investigated via theoretical analyses at the quantum mechanical level. A molecular dynamics simulation at the quantum mechanical level revealed that as the salt concentration increases, the ion-water interactions became stronger, leading to a lower diffusivity and a lower electronic band gap. These imply that the superconcentrated aqueous-based electrolytes have high potentials for the sodium-ion battery applications.

Abstract
For the accurate ab initio treatment of large molecular systems, linear scaling methods (LSMs) have been devised and successfully applied to covalently bonded systems as well as to those involving weak intra/intermolecular bonds. Very few attempts to apply LSM to highly conjugated molecules, especially to two-dimensional systems, have so far been reported in the literature. The present article examines the applicability of a LSM, viz., molecular tailoring approach (MTA), to pi-conjugated systems within density functional theory. A few test cases within second order Møller-Plesset framework are also reported. MTA is applied to some one-dimensional pi-conjugated molecules, for which the difference between MTA energy and actual energy is found out to be less than 1 mhartree and also reduced computation time as well as hardware requirements. The method is also extended to some small/medium-sized two-dimensional pi-conjugated molecules by developing a systematic algorithm for tailoring such systems. However, for such systems, although the energies are in error by a few millihartrees, gradients are found to match reasonably well their actual counterparts. Hence, geometry optimization of these systems within MTA framework is attempted. The geometries thus generated are found to be in good agreement with their actual counterparts, with the actual single point energies matching within 1 mhartree, along with reduced computational effort. These results point toward the potential applicability of MTA to large two- and three-dimensional pi-conjugated systems.
