AIST Develops New Cobalt-free, Mixed Oxide Cathode Material with Iron for Li-ion Batteries; Lower Cost with Good Performance

Green Car Congress

Researchers at Japan’s National Institute of Advanced Industrial Science and Technology (AIST), in collaboration with Tanaka Chemical Corp., have developed two cobalt-free mixed metal oxide cathode materials for Li-ion batteries containing 20% iron: Li 1+x (Fe 0.2 Mn 0.4 ) 1-x O 2 and Li 1+x (Fe 0.2 Mn 0.6 ) 1-x O 2.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

They include the desire to increase the driving range of more modestly priced electric cars from 150 to well over 500 km, and the need to lower the cost and provide maintenance-free technologies for grid applications. Note the trend in abundances of Al > Ca > Mg > Na > Li, and Fe > Mn > Ni > Co. —Grey and Tarascon.

Envia Systems announcement may herald the first wave of DOE-supported commercial high energy density Li-ion cells with Si-C anodes

Green Car Congress

As an example, the military’s BB-2590 Li-ion battery used in a range of portable systems calls for a cycle life of ≥224 and ≥ 3 years.). LIB capacity is limited in part by the intercalation of Li ions by the anode material—i.e., Envia is targeting its high energy density Li-ion cells at plug-in hybrid and electric vehicles.
