UrduEngineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long lasting, and energy dense. It holds promise for a wide range of applications from grid storage to electric vehicles.

Chemists Settle Battery Debate, Propel Research Forward
UPTON, NY—A team of researchers led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has identified new details of the reaction mechanism that takes place in batteries with lithium metal anodes. The findings, published today in Nature Nanotechnology, are a major step towards developing smaller, lighter, and less expensive batteries for electric vehicles.
Lithium-Ion Battery Research “Flowers”
Scientists improved the performance of a battery electrode material with a unique flower-shaped nanostructure.
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.
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.
CFN User Spotlight: Nik Singh Seeks Better Battery Materials
Since 2011, Nikhilendra (Nik) Singh has been a senior scientist in the Materials Research Department at the Toyota Research Institute of North America. His quest to find alternatives to lithium-ion batteries has brought him to Brookhaven Lab’s Center for Functional Nanomaterials (CFN).
Go With the Flow: Scientists Design New Grid Batteries for Renewable Energy
Scientists at Berkeley Lab have designed an affordable ‘flow battery’ membrane that could accelerate renewable energy for the electrical grid.
