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.

Are electric vehicles safer than combustion engine vehicles?

Electric Vehicles India

Yesterday also we get to hear a similar incident from Okinawa where the electric scooter had been parked in a garage and being recharged in the night when a blast had occurred. So let us now talk about Lithium-ion (Li-ion) batteries, as it is the most preferred battery pack in current electric vehicles. Chemistries used.

TU Graz team uses monocrystalline Si as Li-ion anode; integrated micro batteries for on-board sensors

Green Car Congress

Electrochemists at TU Graz have used single crystalline acceptor-doped Si—as ubiquitously used in the semiconductor industry—as anode material for rechargeable Li-ion batteries. This increase amounts up to 300% if we refer to amorphous silicon (a-Si) and complete electrochemical lithiation (0 mV vs Li/Li + ).
