iElectrolyte and Echion demonstrate lithium ion battery cells with ultra long cycle life

Echion Technologies (Cambridge, UK) and iElectrolyte (Osaka, Japan) have demonstrated ultra-long cycle life Li-ion pouch cells.  These cells combined Echion Technologies’ Mixed Niobium Oxide (XNOTM) anode materials with iElectrolyte’s ionic liquid electrolytes which resulted in >98% capacity retention after 1000 cycles (1C/1C cycling). This is forecasted to provide at least >12,000 to standard cycle life limits of 80% of initial cell capacity.  This paves the way to the sustainable electrification of high performance applications.
