SLAC, MIT, TRI researchers advance machine learning to accelerate battery development; insights on fast-charging

Green Car Congress

Scientists have made a major advance in harnessing machine learning to accelerate the design for better batteries. He said the results overturn long-held assumptions about how lithium-ion batteries charge and discharge and give researchers a new set of rules for engineering longer-lasting batteries.

Cornell team develops aluminum-anode batteries with up to 10,000 cycles

Green Car Congress

Friend Family Distinguished Professor of Engineering, have been exploring the use of low-cost materials to create rechargeable batteries that will make energy storage more affordable. These materials could also provide a safer and more environmentally friendly alternative to lithium-ion batteries. They also have a very long cycle life.

Researchers devise electrode architectures to prevent dendrite formation in solid-state batteries

Green Car Congress

Interest in higher energy-density batteries that pair alkali metal electrodes with solid electrolytes is high; however, such batteries have been plagued by a tendency for dendrites to form on one of the electrodes, eventually bridging the electrolyte and shorting out the battery cell.

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. The metal then shrinks again during discharge, as the battery is used.

MIT team develops first supercapacitor made entirely from neat MOFs, without conductive additives or binders

Green Car Congress

Researchers at MIT have shown that a MOF (metal-organic framework) with high electrical conductivity—Ni 3 (2,3,6,7,10,11-hexaiminotriphenylene) 2 (Ni 3 (HITP) 2 )—can serve as the sole electrode material in a supercapacitor. The supercapacitor field was (but will not be anymore) dominated by activated carbons.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V) V versus Li/Li +. —Zhu et al.
