[Case Study] Investigation of Graphene Materials for Li-S Batteries
"Materials Studio" can perform battery property calculations [Case Study] Here we introduce a paper case.
By using nitrogen and metal-doped graphene for the cathode, we analyze the adsorption energy on the metal part with respect to lithium polysulfide intermediates. ◎ Calculation Model Using the DMol3 module in the 'Materials Studio' quantum mechanics calculations - The adsorption energy was determined by performing energy calculations on the structure. - Similar calculations were conducted for various polysulfides and patterns of metal atoms on graphene, allowing for comparisons of the relationship between the number of sulfur atoms in polysulfides and the adsorption energy. ◎ Discussion of the Obtained Physical Property Values - Various PDOS and energy values for Li2Sn/AM were presented. - It was observed that when Cr, Fe, Mn, and Cu were used among the metals investigated, there is a strong interaction between polysulfides and Co-N4/graphene, and that this interaction strengthens as the chain length of the polysulfides decreases. 【Product Features】 ■ Also optimal for "Materials Informatics (MI)" ■ Simulation software that streamlines material development ■ Helps in the development of new materials more efficiently and easily *For more details, please feel free to contact us.
