Energy needs of a submarine travelling underwater is met by energy storage systems. At the same time, the systems and devices used in submarines require more energy with the developing technology. Storing more energy in a limited volume is the most important problem in submarine design. in addition, the long duration of submersion time, the ability to carry out operations without being seen by the enemy, the ability to escape from the enemy quickly, the shorter battery charging time when floating in the water are other important features sought in submarines. Battery energy density is necessary for submarines to perform the aforementioned actions. in this scope, different battery technologies and other energy storage systems are compared with Li- ion battery technology. Characteristic parameters such as energy, power, cost are also used in the comparison. As a result, Li- ion battery technology, which has a high energy density, has become an alternative to the lead-acid battery technology used for energy storage in submarines in recent years, thanks to its advantages such as increasing the submersion time, reducing the indiscretion rate, reducing maintenance requirements and long lifespan. Therefore, it is seen that the first Li-ion battery technology for submarine is used in Japanese Soryu Class. Although Li-ion batteries have started to find application opportunities with the advantages they provide, they are the focus of this study, especially since the safety standards to be used in submarines have not been fully established. Considering the needs and characteristics of the submarines, it was mentioned that the batteries used in the submarines should be tested separately as both the cell and the battery system (battery management system, cooling, ventilation). it has been determined that there is no Li-ion battery standard used in submarine propulsion systems worldwide. TS EN 62619, TS EN 62620, VG 96932-120, NAVSEA S9310-AQ-SAF-010, Türk Loydu and DNVGL, which are among the Li-lon battery standards/rules and guides, have been analyzed. Evaluations about the test methods of these technical standards and guidelines are presented. Evaluations about the test methods of these technical standards and guidelines are presented. Recommendations were made about what the Li-lon battery test methods for submarines should be and which points should be considered. Since the studies on this subject are almost non-existent in the literature, it is aimed to contribute to the literature on the creation of Li-lon battery standards to be used for propulsion system in submarines.
