More than 9 in 10 new emerging battery technologies are based on lithium batteries. That's 90% of all R & D on new emerging battery technologies are focused on making Lithium better. This is especially true in the graphene technologies and anode - cathode relationships where new nano technologies are being applied, atomic levels etc. https://www.v3.co.uk/v3-uk/news/3029207/mit-university-uncovers-new-lithium-battery-design-that-increases-performance
