Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Faradion Limited was established in 2011 to develop low-cost, non-aqueous sodium-ion (Na-ion) rechargeable batteries.

Amorphous titanium dioxide nanotube anodes for sodium-ion batteries show ability to self-improve specific capacity

Green Car Congress

However, Na-ion batteries have exhibited weak charge-discharge behavior except at high temperature—indicative of sluggish kinetics in standard carbon anodes. TiO 2 is one of a few transition metal oxide materials that intercalates Li ions at reasonably low voltage (~1.5 Earlier post.). This is highly unusual material behavior.
