Tohoku, UCLA team advance 4V-class metal-free organic Lithium-ion batteries; croconic acid cathode

Green Car Congress

A joint research team from Tohoku University and the University of California, Los Angeles (UCLA) has made a significant advance towards high-voltage metal-free lithium-ion batteries by using a small organic molecule: croconic acid. An open-access paper on their work is published in the journal Advanced Science. —Katsuyama et al.

Chalmers team develops structural battery that performs 10x better than previous versions

Green Car Congress

It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material. The structural battery uses carbon fiber as a negative electrode, and a lithium iron phosphate-coated aluminum foil as the positive electrode. The carbon fiber acts as a host for the lithium and thus stores the energy.

Nano-vault architecture alleviates stress in Si-based anodes for Li-ion batteries

Green Car Congress

New research conducted by the Okinawa Institute of Science and Technology Graduate University (OIST) has identified a specific building block that improves the anode in lithium-ion batteries. Traditionally, graphite is used for the anode of a lithium-ion battery, but this carbon material has major limitations.

These materials could also provide a safer and more environmentally friendly alternative to lithium-ion batteries. This magnified image shows aluminum deposited on carbon fibers in a battery electrode. The group previously demonstrated the potential of zinc-anode batteries. A paper on the work is published in Nature Energy.
