Lithium imide is an inorganic compound with the chemical formula Li
. It is a white solid that turns brick red in sunshine.

\rm \ 2Li_2NH \rightarrow LiNH_2 + Li_3N

After vacuo heating, the mixture returns to white.[1]

It can be synthesized by the decomposition of lithium amide:

\rm \ 2LiNH_2 \rightarrow Li_2NH + NH_3

Its crystal structure is similar to lithium oxide (a = 504pm) and its density is 1.48g/cm3. It is also a strong base that is able to react with many organic compounds.[1]

Leyden Energy is working on battery technology involving lithium imide. They state that they expect 10% more charge time and double the battery lifespan, but expect it not to be available in mass consumer products until 2014.[2]
