Additionally, any excessive external pressure to the edge of the cell could cause a short circuit. This article will focus on the testing for burrs and particles inside the materials of lithium ion batteries. Figure 3.
Soft-shorts are diagnosable but also transient, and not every technique works for a given battery system. Soft-shorts could be anything from a forest of lithium growths accounting for >95% of the current flow to a thin dendrite in a crack or grain boundary that only decreases the cell impedance by 10%.
Once the temperature of LiBs surpasses 90 °C, the exothermic chemical reactions within the battery accelerate, initiating a positive feedback loop of increased heat generation. The escalating temperature can lead to thermal runaway, ultimately resulting in fires and explosions [2, 3].
Solid-state batteries with lithium metal anodes present the highest energy density batteries for applications in electric vehicles, leading to massive R&D investments over the past decade. Although most research focuses on preventing lithium metal dendrites that eventually short the battery, the nature of these shorts remains elusive.
Although most research focuses on preventing lithium metal dendrites that eventually short the battery, the nature of these shorts remains elusive. Soft-shorts, in particular, receive little attention or are not recognized, even in published data.
The most likely mechanism of short here seems to be the physical deformation of the battery which leads to a conductive path between the electrodes. The abused batteries are then cycled in the devices and the testing data are logged. Batteries developing ISC due to drop is a probabilistic event.
