A substantially high ion conductivity (~10 −4 S cm –1 ) and lithium-ion transference number (0.54) are obtained due to weak interactions between ‘hard’ (charge dense) Li + ions and the ‘soft’ (electronically polarizable) –C≡N group of Adpn. Resources Prakash, P., Aguirre, J.

The demand for domestically produced and sustainably sourced battery metals has grown at a near insatiable rate over recent years, as the domestic manufacturing capacity of lithium-ion batteries has grown exponentially from less than 50 GWh/year to now more than 700 GWh/year of operational and announced capacity.

Aside from the lithium needed to produce modern lithium-ion batteries, much attention is focused on the cost of the materials used for EV battery cathode production. Cobalt is an important ingredient in lithium-ion battery cathode production, accounting for about a quarter of the cost of the battery. 202103050.
