Abstract
As batteries become essential to modern society, concerns surrounding their safety have grown significantly, particularly regarding the danger of electrolytes in used batteries. Among the general public, battery electrolytes are frequently viewed as inherently toxic, corrosive, and high environmental risk, regardless of battery chemistry or condition. From the perspective of a battery scientist, this perception often diverges significantly from scientific risk assessment. This opinion paper reflects on how public fear of battery electrolytes has developed, the reasons for its persistence, and how it contrasts with established knowledge in electrochemistry and materials science. It is important to recognize that while battery electrolytes are hazardous under certain conditions, the real-world risks associated with used batteries are often overstated. This gap between perception and reality has important implications for recycling behavior, regulatory policy, and public trust in energy technologies. Finally, the discussion highlights the responsibility of battery scientists to engage more actively in risk communication and proposes strategies to foster a more balanced, evidence-based public understanding of electrolyte hazards.
