The chemistry of the Lithium–Thionyl Chloride (Li–SOCl₂) battery has long held a strategic role in applications requiring extremely long storage life, wide temperature tolerance and low self-discharge. For example, a study by the Sandia National Laboratories reported that a Li–SOCl₂ “D”-cell was optimized for low-rate discharge (~70 mA) and rated for service lives measured in years, with the cell achieving approximately 16 Ah under those conditions (Source:www.sandia.gov).
Safety investigations by the United States Department of Energy (DOE) produced a technical report indicating that energy densities in Li–SOCl₂ cells of 500–600 Wh/kg had been achieved, even approaching values comparable to high-explosives in earlier designs. (Source:www.osti.gov)
More recently, research from the Chinese Academy of Sciences has shown that by incorporating molecular iodine (I₂) into a SOCl₂ electrolyte, the discharge rate and even rechargeability of Li–SOCl₂-type systems can be improved, indicating that technological innovation is still advancing in what has been a “mature” chemistry.

Given these dynamics, significant specialized performance attributes, safety and reliability requirements, and evolving innovation trends, the landscape for Li–SOCl₂ batteries is evolving rapidly. According to Kings Research, the global lithium thionyl chloride battery market is projected to reach USD 13.46 billion by 2031.
