<div dir="ltr">Dear Prof. Blaha,<br><div><br></div><div> I think the structure as used by me & as can be used by downloading Graphene CIF file from material project database are same with different representation. I have checked the XRD of both the structures in VESTA & they are providing the same XRD pattern for both the structures. In this regard lithiation voltage for both the cases should be same. However the bandstructures need special k points which is available for hexagonal lattice & not for this monoclinic lattice. However, if the voltage is accurate I will not bother for the band structure.</div><div><br></div><div>with kind regards,</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, 30 Dec 2022 at 19:08, shamik chakrabarti <<a href="mailto:shamik15041981@gmail.com">shamik15041981@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Specially if I want LiC6 unit cell?...</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Dec 30, 2022, 18:47 shamik chakrabarti <<a href="mailto:shamik15041981@gmail.com" target="_blank">shamik15041981@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Dear Prof. Blaha,<div dir="auto"> . . . . . .

Start with graphite, remove the atoms at the second z=0.75 layer and <br>
eventually add some vacuum along z.<br>
