WebMay 13, 2024 · When a tube inside the pack is broken, it releases a chemical that reacts with water inside the pack. This reaction absorbs heat energy and quickly cools down the contents of the pack. Figure 2.9. 4: This pack gets cold due to an endergonic reaction. Many other chemical processes involve endergonic reactions. WebMay 2, 2024 · It is worth to observe that an amount of released energy (in any exothermic reactions, the active participant of which is lithium) must depend heavily on the lithium amount in an anode, i.e. on SOC. Notably that this is true for both lithium intercalated into graphite 31 and lithium precipitated (in the course of cells cycling) on an anode surface.
