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.

Rice University scientists have used a seamless graphene-carbon nanotube (GCNT) electrode to store lithium metal reversibly and with complete suppression of dendrite formation. The areal capacities of the GCNT-Li are from 0.4 to 4 mAh cm -2 , represented by GCNT-Li-0.4 to GCNT-Li-4. Credit: ACS, Raji et al.

University of Sydney team advances rechargeable zinc-air batteries with bimetallic oxide–graphene hybrid electrocatalyst. Cheaper to produce than lithium-ion batteries, they can also store more energy (theoretically five times more than that of lithium-ion batteries), are much safer, and are more environmentally friendly.

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. The researchers focused mainly on the favorable cost-performance comparisons between their sodium-ion battery and lithium. —Lee et al.

Improvements to a class of battery electrolyte first introduced in 2017—liquefied gas electrolytes—could pave the way to replacing the graphite anode with a lithium-metal anode. As demonstrated in this earlier work, the solvent itself, rather than the salt, plays a more critical role in stabilizing the Li metal.

Researchers have achieved a significant boost in the storage capacity of magnesium-ion batteries through a new design for the cathode and a new understanding of the electrolyte. Magnesium ion is known to be hard to insert into a host. More than that, magnesium ions produced in that way move extremely slowly in the host.
