Title:FlexibleWater-BasedZincIonBatterieswithLow-TemperatureDurabilityandMoistureRetentionEnabledbyMulti-FunctionalGelElectrolytes
Abstract:
Flexibleandwearableelectronicdevicesareemergingasanewtrendinvariousapplications,suchashealthcaremonitoring,smarttextiles,andflexibledisplays.Topowerthesedevices,flexiblebatterieswithhighperformanceandsafetyarehighlydesirable.Inthispaper,weproposeaflexiblewater-basedzincionbatterywithmulti-functionalgelelectrolytesthatexhibitexcellentlow-temperaturedurabilityandmoistureretentionproperties.
1.Introduction:
Flexiblebatterieshavegainedsignificantattentionduetotheirsuitabilityforwearableelectronicsandtheirpotentialforapplicationinharshenvironments.However,conventionalliquidelectrolytesusedinbatteriessufferfrompoorstabilityandsafetyconcerns.Herein,weintroduceanovelgelelectrolytesystemthataddressestheselimitationsthroughacombinationofgelationagentsandadditives.
2.GelElectrolyteDesign:
Thegelelectrolyteusedinthewater-basedzincionbatteryisbasedonapolymermatrix,whichprovidesmechanicalsupportandpreventstheleakageoftheelectrolyte.Variousgelationagents,suchaspolyacrylamideorpolyvinylalcohol,canbeusedtoformastablegelnetwork.Additionally,incorporatingmoisture-retainingadditives,likeglycerolorpolyethyleneglycol,enhancestheretentionofwaterwithinthegelelectrolyte,ensuringthelongevityanddurabilityofthebattery.
3.Low-TemperatureDurability:
