At the政治大学（UPV），属于CMT-MoteresTérmicos研究所，科学家正在合作进行各种国家和国际项目，以增强目前在电动汽车中使用的锂离子电池的安全性。

正如CMT-MotoresTérmicos的科学家AntonioGarcía所说，汽车部门的未来在很大程度上，即使不是仅仅取决于对锂离子电池的巨大使用。目前有一些问题，例如热稳定性，可能会影响用户的安全性

Lithium-ion batteries under certain conditions are not safe. There is a phenomenon known as thermal runaway, which can end up causing the battery to catch fire, with the consequent risk to the occupants of the vehicle.

加西亚补充说：“在此过程中释放的热能约为电池中包含的电能的5.4倍，因此必须采取极端预防措施。电池的热不稳定性可能在高需求条件下发生，例如在快速充电期间。如果这不能很好地管理，它可以进入热失控并开始火灾。值得注意的是，德国城市已经禁止在地下车库停车。”

For such risks to be reduced, the UPV’s CMT-Motores Térmicos team is at present working on two European and two other national projects. They aim to better comprehend all the issues linked with the thermal runaway of lithium-ion batteries, both current and those that will make their way to the future market in the coming 15 years.

我们正在运用40多年的工作，专注于燃烧发动机，以了解影响锂离子电池的这种现象。我们甚至想知道电池中燃烧过程的最小细节，以帮助使其尽可能安全。我们已经有了第一个结果。

Among these is the development of an experimental installation, in partnership with AVL Ibérica, to be able to envision how the combustion process of a battery tends to develop.

加上对已排放的气体的分析，该过程的物理化学表征将能够在不同条件下进行，例如不同的电荷状态，环境的组成等。这将使化学化的发展动力学机制与该过程有关。

The UPV team is also collaborating on the DETEBAT-VE project, financed by the Generalitat Valenciana, which is concentrated on reorienting companies that currently offer services to Ford Almussafes towards electrification.

The objective of the project is to create a high-energy content battery pack demonstrator that allows the development and validation of the essential technologies to increase its driving range, safety and sustainability. From the CMT we work on the aspects of safety, thermal control and development of the battery energy management system。

NASA Interest

The study performed from the laboratories of this group at the UPV’s CMT-Motores Térmicos has piqued the interest of huge multinationals in the automotive sector, as well as the US space agency, located in NASA.

“该机构拥有一个专门针对这些电池的部门，这对于航空部门来说也是关键。去年12月，我们在NASA航空航天电池研讨会上介绍了我们在该领域的最新工作的结论，这是非常受欢迎的，”加西亚说。

On the Future of the Automotive

在这些项目的帮助下，CMT-MoteresTérmicos集团为该行业的未来提供了所有知识。

Antonio Garcia stated, “不会有单一的获胜技术，“”Because the future is eclectic. We have a global problem that is CO₂and, without the integration of hybrid electric vehicles (HEV), plug-in hybrids (PHEV), 100% electric vehicles (BEV), Fuel Cells, e-fuels, H₂...不可能达到减少2050年排放的目标。”

“We are working on this integration and, in this specific case, on helping to guarantee the maximum safety of lithium-ion batteries, which are key today and even more so in the not-so-long-term future，”安东尼奥·加西亚（Antonio Garcia）补充说。
