【Abstract]Inorder to investigate the working characteristics of sodium-ion power batery under practical application conditions，this papercomparesandanalyzes through experimenttheperformanceofsodiumion power bateryand lithiumironphosphate battery withthesame volume.Results indicate that sodium-ion power batery has god charge and discharge capacityat high temperature，normal temperatureandlow temperature，anditschargeand discharge temperatureriseis lower thanthatof lithium ironphosphatebatery.Atnormal temperature，after22O4charginganddischarging cycles，the capacity of sodium battery remains at 82.02% . At a temperature of 45C ，the capacity of sodium battery remains at 80.56% after1 565 charging and discharging cycles.Results also indicate that at a low temperature of -30C ，the performance of sodium-ionbatteryissignificantlybeterthanthatoflithium-ironphosphatebatterymaking itmoresuitableaspowerbatery for new energy vehicles insevere cold areas.
