Building on earlier work, researchers in China have fabricated a hierarchical metal-organic nanocomposite for use as a cathode in sodium-ion batteries (SIBs). Moreover, the transition metal ions participate in the electrochemical reaction at high potentials that is helpful to raise the battery voltage. —Huang et al.

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. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a new battery cell production process that coats the electrodes of the energy storage cells with a dry film instead of liquid chemicals. BroadBit uses it to produce new types of sodium-ion batteries. © Fraunhofer IWS.

The US Department of Energy (DOE) announced up to $45 million in funding ( DE-FOA-0002760 ) to support the domestic development of advanced batteries for electric vehicles. Advanced batteries capable of safe, rapid charging are necessary to appeal to these Americans who are unable to charge cars at home for long periods of time.

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.

A team of researchers from institutions in China and the US report the design of a negatively charged graphene composite separator for the effective suppression of the polysulfide shuttling effect in Li-sulfur batteries. Therefore, despite extensive efforts, the improvement to date remains rather unsatisfactory, especially in energy density.
