Batteries.

Researchers from Sandia National Laboratories have developed a radio-frequency detector that monitors a lithium-ion battery’s health while cycling— a first for commercially available batteries.

Placed inside the battery, the paper-thin magnetic resonance detector could help researchers better understand and characterise batteries to improve them for renewable storage and national security applications.

Researchers at Australia's Deakin University have reported a way of using common industrial polymers to create solid electrolytes for solid-state lithium-ion batteries.

The scientists’ new solid polymer electrolyte system, based on a new lithium transport mechanism, was weakly bonded to the lithium-ion to replace the liquid solvents typically used as electrolytes in battery cells.

Japanese ceramics manufacturer NGK Insulators and German BASF New Business (BNB) are expanding their business relationship to develop the next generation of sodium-sulfur batteries.

NGK and BNB, a wholly owned subsidiary of the German chemical company BASF, have entered into a joint development agreement (JDA) to develop sodium-sulfur (NaS) batteries for stationary applications.

Power utility E.ON is replacing lead-acid backup power batteries from a distribution substation in the north west of Hungary with Saft’s nickel cadmium technology. 

The pilot project aims to show how Saft’s Uptimax maintenance-free nickel pocket plate batteries can be installed as a direct Plug and Play replacement for time-served lead-acid batteries.
