AN37SFossil energiesExcellence in thermal analysis and calorimetry Self discharge of lithium batteries The temperature of the calorimeter ismaintained at 70℃. Batteries of type CR1220 are studied. 9 batteries are superimposed inside thevessel. Between two batteries a layer of paper isinserted to insulate electrically thebatteries from each other. InstrumentC80 from RT to 300℃ After the introduction, the calorimetricoutput passes by a maximum of78 pW. (or 78/9=8.7 pW by battery)After 65 hours the two vessels :measure and reference are inverted.The mid-point between the traceobtained before inversion and thetrace after 80 hours gives the positionof“calorimetric zero”. It means that after 55 hours the 9batteries dissipate 24 uW whichcorresponds to 24/9=2.7 pW bybattery. www.setaram.com - sales @setaram.com
