  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
