Lithium-ion　batteries　(LIBs)　are　considered　as　irreplaceable　energy　storage　technologies　in　modern　society.　However,　the　LIBs　encounter　a　sharp　decline　in　discharge　capacity　and　discharge　voltage　in　low　temperature　environment　(＜　0　degrees　C),　which　cannot　meet　growing　demands　for　portable　electronics　and　electric　vehicles　at　low　temperature.　In　particular,　the　LIBs　experience　the　dramatical　decrease　of　lithium-ion　conductivity　in　electrolyte　and　sluggish　charge　transfer　process　within　the　electrode　at　low　temperature.　Therefore,　rational　design　on　the　low-temperature　electrolyte　is　critical　important　for　achieving　excellent　performance　of　LIBs　to　broaden　their　application　scenarios　at　low-temperature.　To　this　end,　in　this　review,　we　firstly　discuss　the　origination　on　the　LIBs　performance　degradation　at　low　temperature.　Then,　the　corresponding　strategies　on　rational　tailoring　traditional　electrolytes　(lithium　salts　and　the　solvents,　including　carbonate-based,　carboxylate-based,　ether-based　and　ionic　liquid　solvent),　and　the　new　emerging　electrolytes　(e.g.,　locally　high　concentrated　electrolyte,　liquefied　gas　electrolyte　and　polymer　electrolyte)　towards　low-temperature　LIBs　are　introduced.　Finally,　the　remaining　challenges　and　future　perspectives　for　low-temperature　LIBs　are　presented.　It　is　expected　that　this　review　will　shed　fresh　light　on　electrolyte　design　for　low-temperature　LIBs　and　accelerate　widespread　application　of　LIBs　for　low　temperature　environment.(c)　2022　Elsevier　B.V.　All　rights　reserved.
