Because of the increase of using mobile device and the growth of electric vehicle market, portable energy storage system has been required. Secondary batteries which can store electric energy as chemical energy are one of the promising candidates of energy storage system because of their high energy density. Increasing the energy density and stability of battery and increasing ion conductivity of solid electrolyte and lowering contact resistance between solid-electrolyte and electrode. We are trying to develop anode material of lithium metal battery which made of conductive MOF (Metal-Organic Framework). Lithium-ion intercalation can change the electrical conductivity of the conductive MOF and it can be used for preventing the formation of lithium dendrite. Generally, MOF have high porosity and they are lithiophilic. But because they are electrically insulating, we are trying to combine MOF and conducting polymer together so that can storage the lithium metal inside MOF. In solid ion conductors, anion is bonded to a bulk rigid structure which prevents the anion movement and limits the anion conduction and ion polarization. This eventually enhances the cation conduction and cation transference number. Anions, which are weakly coordinating with cations, are known as weakly coordinating anions and its charger is delocalized over the entire surface. Weak coordination between cation-anion inhibits the ion pair formation and enhances the cation mobility. Moreover bulk structure of the anion can lower its mobility and limits the anion conduction, thus improves the cation transference number and overall conductivity.  • Recently, the LiDAR industry has received attention and been growing, but the mechanical structure LiDAR currently used has a limitation in price efficiency and
