纳米多孔纤维素中锂原子的表面诱导$\rm Li_2$断裂存储

Lithium atom storage in nanoporous cellulose via surface induced $\rm Li_2$ breakage

Mathias Boström, Dan Huang, Weihong Yang, Clas Persson, Bo E. Sernelius

摘要:

我们证明了一个物理机制,提高了分裂的双原子$\rm Li_2$在纤维素表面。这种分裂的起源可能是表面诱导的双原子激发态共振排斥。然后,原子Li自由地与纤维素表面形成物理或化学键,甚至扩散到纤维素层结构中。这允许纳米多孔纤维素中原子Li的增强的存储容量

英文摘要:

We demonstrate a physical mechanism that enhances a splitting of diatomic $\rm Li_2$ at cellulose surfaces. The origin of this splitting is a possible surface induced diatomic excited state resonance repulsion. The atomic Li is then free to form either physical or chemical bonds with the cellulose surface and even diffuse into the cellulose layer structure. This allows for an enhanced storage capacity of atomic Li in nanoporous cellulose
