Longer Lasting Sodium-Ion Batteries on the Horizon
A new longer-lasting sodium-ion battery design is much more durable and reliable in lab tests. After 300 charging cycles, it retained 90 percent of its charging capacity.
New scalable method resolves materials joining in solid-state batteries
Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a scalable, low-cost method to improve the joining of materials in solid-state batteries, resolving one of the big challenges in the commercial development of safe, long-lived energy storage systems.
Longer-lived lithium-metal battery marks step forward for electric vehicles
Researchers have increased the lifetime of a promising electric vehicle battery to a record level.
Mapping Performance Variations to See How Lithium-Metal Batteries Fail
Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion.
An anode-free zinc battery that could someday store renewable energy
Researchers reporting in ACS’ Nano Letters have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials.
Spontaneous Formation of Nanoscale Hollow Structures Could Boost Battery Storage
An unexpected property of nanometer-scale antimony crystals — the spontaneous formation of hollow structures — could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion batteries to hold more energy and therefore provide more power between charges.
Peering into Functioning Batteries with Sooyeon Hwang
Using electron microscopes, Hwang—a materials scientist at Brookhaven Lab’s Center for Functional Nanomaterials (CFN)—characterizes the structure and chemistry of operating battery electrode materials.
Chasing Lithium Ions on the Move in a Fast-Charging Battery
Atomic distortions emerging in the electrode during operation provide a “fast lane” for the transport of lithium ions.
