Understanding how lithium-ion batteries degrade over time and with use in different applications is crucial for designing better energy storage systems and accelerating the transition to net-zero. Typically, new battery designs are tested in a laboratory environment to study how their performance degrades prior to commercialisation. However, as battery lifetimes improves with new designs, these tests take longer, meaning commercialisation needs to either be delayed or released without testing to end of life. This project seeks to develop physically informed accelerated test protocols for lithium-ion batteries based on real world conditions. Numerical models will be combined with experimental degradation testing to optimise battery test protocols and provide a statistical link between accelerated testing lifetime and predicted lifetime in real world applications. The project will use electric vehicles as a target application, but it is anticipated this technique will be applicable to all applications where lithium-ion batteries are used for energy storage.

了解锂离子电池如何随着时间的推移和在不同应用中的使用而降解，对于设计更好的能量存储系统和加速向净零过渡至关重要。通常，新的电池设计会在实验室环境中进行测试，以研究在商业化之前它们的性能是如何下降的。然而，随着新设计延长电池寿命，这些测试需要更长的时间，这意味着商业化要么需要推迟，要么需要在没有测试的情况下发布到寿命结束。该项目致力于开发基于真实世界条件的锂离子电池物理知情加速测试协议。数值模型将与实验退化测试相结合，以优化电池测试方案，并在实际应用中提供加速测试寿命和预测寿命之间的统计联系。该项目将使用电动汽车作为目标应用，但预计这项技术将适用于所有使用锂离子电池储存能量的应用。
