This study explores the theoretical potential of using thermal runaway in lithium-ion batteries for propulsion systems. Lithium-ion batteries, essential in various applications, are prone to thermal runaway, a phenomenon that can cause rapid temperature increases and energy release due to electrochemical and chemical reactions within the battery. While traditionally considered a safety risk, recent research has suggested leveraging this phenomenon for energy conversion and propulsion technology development. This paper aims to construct theoretical models of electrochemical systems, analyze the relationship between voltage and heat generation, and investigate how to control thermal runaway for desired thrust generation. The study presents three key scenarios: a system without chemical reactions at low temperatures, a system where chemical reactions occur at high temperatures, and a system involving rapid flow and high-speed reactions. By analyzing the linear relationship between voltage and heat generation, the research demonstrates the feasibility of controlling heat output through voltage adjustments. Additionally, the study evaluates the potential of using the combustion of gases produced during thermal runaway for propulsion, highlighting its applicability in space debris removal and other space-related activities. The findings suggest that controlling the combustion mechanism during thermal runaway could lead to the development of a novel electrochemical propulsion technology for the space industry.
