Facile　preparation　of　organohydrogel　electrolyte　integrated　with　good　anti-freezing　property,　toughness,　transparency,　conductivity　and　thermoplasticity　is　important　and　still　remains　challenging.　Novel　conductive　and　tough　poly(vinyl　alcohol)/sodium　alginate/glycerol　(PVA/SA/Gly)　composite　organohydrogel　electrolytes　were　obtained　by　a　simple　method　in　this　paper.　PVA　and　SA　was　firstly　dissolved　in　a　mixed　solution　of　distilled　water　and　glycerol　and　the　PVA/SA/Gly　organohydrogel　was　obtained　by　the　freezing-thawing　process,　then　PVA/SA/Gly　organohydrogel　was　immersed　into　the　saturated　NaCl　aqueous　solution.　During　the　soaking　process　NaCl　would　enter　into　the　PVA/SA/Gly　organohydrogel　to　increase　the　gel　strength　and　conductivity.　The　PVA/SA/Gly　organohydrogel　electrolytes　performed　the　high　toughness　with　the　tensile　strength　and　elongation　at　break　of　1.43MPa　and　558%,　respectively.　Moreover,　the　PVA/SA/Gly　organohydrogel　electrolytes　behaved　high　transparency,　anti-freezing　property,　conductivity　and　thermoplasticity　due　to　the　incorporation　of　glycerol.　This　paper　provides　a　new　preparation　method　for　the　high-performance　organohydrogel　electrolyte.　(C)　2020　Elsevier　B.V.　All　rights　reserved.
