Batteries on the markettoday still use liquid-type electrolytes, which can result in safety issuescaused by electrolyte leakage. Therefore, studies that search for solid-stateelectrolytes are important for resolving these issues. In this research, acomposite of lithium phosphate-montmorillonite-polyvinylidene fluoride (Li3PO4-MMT-PVDF)has been characterized with the aim of detecting the electrochemicalperformance of Li3PO4 with the addition of MMT. Li3PO4samples were prepared through a solid-state reaction, which was then mixed with MMT, which hada composition ranging from 5 wt% to 20 wt%, and 1 wt% PVDF as a binder. Thischaracterization was conducted with structural, morphological, andelectrochemical aspects. The structural test showed that the X-ray diffraction (XRD) pattern was dominated by Li3PO4 peaks and MMT aluminosilicates. The electrochemical characterization indicatedthat the conductivity value of the composites was greater than that of Li3PO4.The highest conductivity was achieved with a 15 wt% MMT addition, with adielectric-constant value of 74.9 at a frequency of 10 kHz. |
