Sodium-ion batteries are a potential replacement for lithium batteries, but different anodes are needed for the same level of performance. Amorphous carbon is known to be a useful anode, because it has defects and voids that can be used to store sodium ions. Nitrogen/phosphorus-doped carbon also offers appealing electrical properties. In Applied Physics Reviews, researchers describe how they applied basic physical concepts of atomic scale to build high-performance anodes for sodium-ion batteries.Read more

As the inevitable growth of transport electrification continues, the types of batteries that will be used in such vehicles, their charging parameters, infrastructure and timeframes are key considerations that will speed up the transition to electrification.Read more
Sodium-ion batteries offer several advantages over lithium-ion batteries; however, it is difficult to develop sodium cathodes, materials through which electrons can enter a battery. Many candidate materials are unstable or cannot withstand high voltages. To find a solution, researchers turned to nature. They created a porous system of NVP structures, surrounded by a dense shell of reduced graphene oxide. They describe the mammal bone-inspired sodium cathode in the journal Applied Physics Reviews.Read more
A team of researchers has developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured in sterile conditions, under vacuum, this one can be screen printed in normal lab conditions. The device can be used in flexible, stretchable electronics for wearables as well as soft robotics.
Scientists have developed a new way to decipher the atomic-level structure of materials based on data gleaned from ground-up powder samples. They describe their approach and demonstrate its ability to solve the structure of a material that shows promise for shuttling ions through sodium-ion batteries.Read more

Columbia Engineering researchers have found that alkali metal additives, such as potassium ions, can prevent lithium microstructure proliferation during battery use. They used a combination of microscopy, nuclear magnetic resonance, and computational modeling to discover that adding small amounts of potassium salt to a conventional lithium battery electrolyte produces unique chemistry at the lithium/electrolyte interface, and modulates degradation during battery operation, preventing the growth of microstructures and leading to safer, longer lasting batteries.
