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.

NREL licenses Li-ion battery technology to Forge Nano; enhanced safety, durability, and lifetime

Green Car Congress

These lithium-ion batteries feature a hybrid solid-liquid electrolyte system, in which the electrodes are coated with a solid electrolyte layer. Lab-scale testing of NREL’s hybrid solid-liquid electrolyte system has shown increased electrode durability and reliability without compromised electrochemical performance. King, Lamuel A.

Saft and ESMA to Cooperate on Supercapacitor Development, Production and Commercialization; Heavy Diesels First Target

Green Car Congress

The first results will be seen later in 2009, when Saft’s US manufacturing facility in Valdosta, GA begins production of a new generation of asymmetric nickel supercapacitors that will work in combination with batteries on heavy vehicles in a large variety of markets including, but not limited to, industry or public transportation.

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.
