Energy Storage Materials: Discovery and Electrochemistry

电化学储能从未像今天这样重要。开发能够满足全球能源需求的可行的长期解决方案仍然是科学界面临的最关键挑战之一。c社区。在能源成本和可持续性问题日益突出的背景下，国际上对储能（及其合作伙伴能源转换）的关注迅速升温。在我们的国家科学研究委员会发现资助研究过程中，我们有了一个突破性的发现，它正在改变电化学学家对能量存储的看法。我们在这一领域的初步工作发表在2009年的《自然材料》杂志上，并描述了在有限空间内存储能量的“第一次”。这一发现开启了锂硫电池领域的发展，从那时起，锂硫电池的发展就呈指数增长。此外，这一发现为锂（和钠）氧电池的发展指明了道路，并与钠离子电化学一起成为“超越锂离子电池”的新方法的基础。

Electrochemical energy storage has never been more important than today. The development of viable, long-term solutions that will meet global energy needs remains one of the most critical challenges facing the scienti?c community. Amid burgeoning energy costs and sustainability concerns, international focus on energy storage (and its partner energy conversion) has rapidly gained momentum. During the course of our NSERC discovery grant research, we have made a breakthrough discovery that is changing the way electrochemists think about energy storage. Our initial work in this area was reported in Nature Materials, 2009 and described “a first” for energy storage in confined dimensions. This finding kick-started the field of lithium-sulfur batteries that has increased exponentially ever since. Moreover, this discovery helped point the way to developments in Li (and Na)-oxygen batteries, and along with Na-ion electrochemistry has become the foundation for new approaches to “beyond Li-ion batteries”.
