The development of solid-state battery (SSB) technology is driven by the pursuit of safer, more efficient energy storage. SSB cells have several advantages including a lack of liquid electrolyte that can leak and instigate hazardous situations due to its flammability. However, challenges persist including complicated manufacturing, a shorter lifespan due to high electrode-electrolyte interface resistance, and susceptibility to internal short circuits from dendrite growth. Due to these reasons, current semi solid-state batteries (SSSB) are used as a transitional technology. While these SSSB cells still use a liquid electrolyte, their use is reduced and replaced with solid components. There have been limited safety investigations published for SSSB cells, leading this study to focus on the safety of SSSB cells in the event of external short (ESCs) and internal short circuits (ISCs). Failure from short circuit remains one of the most critical threats in batteries, as it can trigger rapid heat generation and ultimately lead to thermal runaway. ESCs occur when the positive and negative terminals of the cell are directly connected through an external resistance, while ISCs arise inside the cell when there are separator failure, mechanical deformation, or abuse conditions. ISCs were induced through the application of a nail penetration test, while ESCs were simulated by connecting the positive and negative terminals of the cell. Whereas ESCs generally result in cell swelling, electrolyte leakage, and smoke, but no fire or explosion, ISCs can cause rapid heat generation, leading to fire, explosion, and smoke, thus posing a higher safety risk. This research provides a comprehensive comparison between ESCs and ISCs, highlighting the distinct characteristics and implications each type possesses for the operational safety of SSSB cells
