Abstract: A battery module for receiving battery cells provides cooling through a cooling fluid. Chilled fluid travels first to the hottest part of the battery module and then continues to gradually less hot areas. As the chilled cooling fluid absorbs heat and travels to cooler parts of the battery module, the heat transfer between the fluid and the battery cells decreases because the temperature differential between the cells and cooling fluid decreases, providing a more even temperature distribution across the battery module. The cooling fluid may be contained in a conduit associated with one or more cooling plates. A plurality of slots provide a precise mechanical support for each battery cell, increasing the heat conduction from the cell to the battery module, protecting the battery module from vibration and decreasing contamination in case of thermal runaway or other damage to the cells.

Abstract: A double-sealed thin film electrochemical pouch cell, comprising a cathode current collector, a cathode, an electrolyte, an anode, and an anode current collector, which is double-sealed by a first inner laminate layer forming a primary seal covered by a second outer polymer layer forming a secondary seal. The second outer polymer layer comprises embedded particles to increase the thermal conductivity of the second outer polymer layer.

Abstract translation: 用于接收电池单元的电池模块通过冷却流体提供冷却。 冷冻液体首先流向电池模块最热的部分，然后继续逐渐减少热区。 随着冷却的冷却流体吸收热量并传播到电池模块的较冷部分，由于电池和冷却流体之间的温差降低，流体和电池单元之间的热传递减小，从而在电池模块上提供更均匀的温度分布 。 冷却流体可以包含在与一个或多个冷却板相关联的导管中。 多个狭槽为每个电池单元提供精确的机械支撑，增加从电池到电池模块的热传导，保护电池模块免受振动，并在散热或对电池的其它损坏的情况下减少污染。
