New method for synthesis of dilithium terephthalate
Апстракт
Nedavno je otkriveno da litijum-tereftalat (Li2tpht) pokazuje veću termičku stabilnost u poređenju sa konvencionalnim anodnim materijalima u litijum-jonskim baterijama [1]. U ovom radu upoređena su dva postupka sinteze pomenutog jedinjenja. Prvi postupak opisan je od strane Kaduka [2], dok drugi pristup predstavlja nov postupak. Prema Kaduku, Li2tpht dobijen je taloženjem iz vodene suspenzije koji sadrži Li2O i tereftalnu kiselinu (H2tpht) u molskom odnosu 1:1. Novi postupak zasnovan je na jednostavnom mlevenju reaktanata, Li2CO3 i H2tpht, u ahatnom avanu. Oba uzorka okarakterisana su pomoću FTIR spektrokopije, TG/DSC i XRD analize. Dobijeni rezultati su međusobno upoređeni i diskutovani.

Recently, it has been discovered that dilithium terephthalate (Li2tpht) shows enhanced thermal stability over conventional anode materials for Li-ion batteries [1]. This investigation compares two ways of synthesis of the mentioned compound. The first one was described by Kaduk [2] and the other approach presents a new procedure. According to Kaduk, Li2tpht is obtained by precipitation from an aqueous suspension containing Li2O and terephthalic acid (H2tpht) in a molar ratio 1:1. The new method is based on a simple grinding of Li2CO3 and H2tpht in an agate mortar. Both samples were characterized by FTIR spectroscopy, TG/DSC and XRD analysis. The obtained results are compared and discussed.
