Lithium-ion batteries are increasingly used in mobile applications where mechanical vibrations and shocks are a constant companion. This work shows how these mechanical loads affect lithium-ion cells. Therefore pouch and cylindrical cells are stressed with vibrational and shock profiles according to the UN 38.3 standard.
In particular, mechanical vibrations and infrequent shock loads affect all parts of a battery including its smallest energy storing part, the accumulator cell, or short cell. Mechanical stress on cell level may cause market durability failures in the long-term and, especially for lithium-ion cells, these failures might pose a safety risk.
Fundamentals of battery technology An automotive lithium-ion battery pack is a device comprising electrochemical cells interconnected in series or parallel that provide energy to the electric vehicle.
However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.
Depending on the direction of motion, the loose mandrel caused serious damage. Lithium-ion batteries are increasingly used in mobile applications where mechanical vibrations and shocks are a constant companion. This work shows how these mechanical loads affect lithium-ion cells.
Depending on the cell design and the loading direction, long-term vibrational loads can have additional detrimental effects on lithium-ion cells compared to standard tests. The demand for secondary batteries increased rapidly during the past decades and is likely to rise in the future.
