温度和放电深度对钠硫电池欧姆内阻的影响
Influence of temperature and depth of discharge on ohmic internal resistance of sodium-sulfur battery
摘要
Abstract
The ohmic internal resistance of sodium-sulfur battery was closely related with temperature and depth of discharge (DOD).The ohmic internal resistances of sodium-sulfur battery with different DOD were measured by pulse discharge test at different temperatures.At a fixed DOD,the ohmic internal resistance increased with the decreasing of temperature,except 100％ DOD.At a fixed temperature,when DOD was in 0-7.14％,the ohmic internal resistance reduced when DOD increased,owing to the consuming of high impedance sulfur layer on the outer surface of β"-Al2O3 ceramic tube.When DOD was in 7.14％-85.70％,the ohmic internal resistance was basically constant.When DOD was in 85.70％-100％,the ohmic internal resistance increased sharply while DOD increased,which was causing by the decrease of effective reaction area of negative electrode.When DOD was in 7.14％-57.14％,the sodium-sulfur battery had fine power characteristic with the open circuit voltage of 2.065-2.079 V.关键词
