Abstract
Bakalaura darba ietvaros komerciāli iegādāts LiNi0,8Mn0,1Co0,1O2 tika izmantots, lai pagatavotu 2 veidu elektrodus, izmantojot atšķirīgas saistvielas - karboksimetilceluloze / stirola butadiēna gumija (CMC/SBR) un polivinilidēnfluorīdu (PVDF). Abu veidu elektrodi tika maisīti ar 2 maisīšanas paņēmieniem – lodīšu dzirnavās un tangenciālā vakuuma maisītāja. Elektrodiem tika veikti elektroķīmiskie mērījum un šķērsgriezuma analīze.
Commercial LiNi0,8Mn0,1Co0,1O2 was used to prepare 2 types of electrodes using different binders - carboxymethyl cellulose / styrene-butadiene rubber (SBR/CMC) and Polyvinylidene fluoride (PVDF). Both types of electrodes were stirred with 2 stirring techniques, a ball mill and tangential vacuum stirrer. Electrochemical measurements and cross-sectional analysis were performed for the electrodes.
