SA视讯   A team of scientists from the universities of Alberta and Toronto have laid out theblueprints for a "quantum battery" that never loses its charge.

SA视讯   加拿大阿尔伯塔大学和多伦多大学的科学家团队为一种永远不会没电的“量子电池”制定了研发计划。

  To be clear, this battery doesn't exist yet — but if they figure out how to build it, it could be a revolutionary breakthrough in energy storage.


  "The batteries that we are more familiar with — like the lithium-ion battery that powers your smartphone — rely on classical electrochemical principles, whereas quantum batteries rely solely on quantum mechanics," University of Alberta chemist Gabriel Hanna said in a statement.


SA视讯   Dark State 暗态

SA视讯   A paper describing the research was published in the Journal of Physical Chemistry C. in July. The battery works by harnessing the power of "excitonic energy" — the state in which an electron absorbs sufficiently charged photons of light.


SA视讯   The researchers found that their resulting battery model should be "highly robust to energy losses," thanks to the fact that their battery is prepared inside a "dark state" where it cannot exchange energy — by absorbing or releasing photons — with its surroundings.

SA视讯   研究人员发现,他们提出的电池模型应该“在能量损失方面具有高稳健性”,这是因为他们的电池是在“暗态”中准备的,而在这种状态下,电池无法通过吸收或释放光子与周围环境交换能量。

  Large Charge 大量电荷

  By breaking down this "dark state" quantum network, the researchers claim the battery could be able to discharge and release energy in the process.


SA视讯   But the team has yet to come up with viable ways of doing so. They will also have to figure out a way to scale the technology for real-world applications as well.

SA视讯   但是该团队还没有找到实现这一过程的可行方法,而且他们还需要想办法把这项技术拓展到实际应用中。
