Lithium salts make batteries powerful but expensive. An ultralow-concentration electrolyte based on the lithium salt LiDFOB may be a more economical and more sustainable alternative. Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance. In addition, the electrolyte could facilitate both production and recycling of the batteries.

The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors. They found that electrodes with a more disordered chemical structure stored far more energy than electrodes with a highly ordered structure.

Researchers have developed a mass synthesis process for sodium-containing sulfides. Mass synthesis of electrolytes with high conductivity and formability is key to the practical use of all-solid-state sodium batteries, thought to be safer than lithium-ion batteries and less expensive, as sodium is far more plentiful than lithium.

All-solid-state lithium-ion batteries offer enhanced safety and energy density compared to liquid electrolyte counterparts, but face challenges like lower conductivity and insufficient electrode contact. In a recent study, scientists have discovered a stable, highly conductive lithium-ion conductor in the form of a pyrochlore-type oxyfluoride. This innovation addresses the need for non-sulfide solid electrolytes, offering higher conductivity and stability and paves the way for advanced all-solid-state lithium-ion batteries with improved performance and safety.

From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers have devised an implantable battery that runs on oxygen in the body. The study shows in rats that the proof-of-concept design can deliver stable power and is compatible with the biological system.
