Thermal Behavior of Used Alkaline Primary Button Batteries Disposed as General Waste

Abstract—The thermal behavior of new (1.5 V) and used (0 V) primary LR1130 alkaline button batteries was investigated by thermogravimetric differential thermal analysis (TG/DTA). The anode (MnO2) and cathode (Zn) from the batteries were mixed with paper or plastic (1:1). Cellulose and polyethylene were used to represent paper and plastic, respectively. The thermal behavior of MnO2, Zn and the separator from both new and used batteries was comparable by TG/DTA using. There was no exo- or endothermic decomposition of Zn and minor exothermic decomposition of MnO2 from new and used batteries. MnO2 and Zn were markedly affected by the thermal decomposition of cellulose. However, cellulose mixed with MnO2 was more of a thermal hazard than when mixed with Zn. Moreover, MnO2 and Zn from both new and used batteries were also affected considerably by the thermal behavior of polyethylene. Therefore, the accidental disposal of used alkaline button batteries shows high potential to lead to an accident.

Index Terms—LR1130, primary alkaline button battery, thermal characteristics, thermal hazard.
