Researchers at Osaka Metropolitan University have developed a novel process for mass-producing high-performance all-solid-state sodium batteries. The team's innovation uses sodium polysulfides to create solid sulfide electrolytes with unprecedented sodium ion conductivity — ten times higher than current standards.

In a significant breakthrough, the University of Liverpool's research team has identified a novel solid material capable of fast lithium ion conduction, potentially revolutionizing the field of rechargeable batteries. Detailed in the Science journal, this discovery introduces a solid-state lithium electrolyte made from abundant, non-toxic elements, offering a viable alternative to the liquid electrolytes used in today's lithium-ion batteries.

Estuaries, where rivers meet the sea, not only provide scenic spots but also present unique opportunities for generating renewable energy through osmotic power. Researchers have developed a new semipermeable membrane that leverages the salt gradients in these waters to produce electricity.

Researchers have now developed diamond quantum sensors which can be used to improve resolution in magnetic imaging. With this innovation, microscale nuclear magnetic resonance spectroscopy also becomes possible.

Researchers have revealed that unstable electrolytes i.e. the material that serves as the transport medium for ions in the battery reaction along with their high level of reactivity with the cathode are responsible for crack formation.

Fluorochemicals are used across many industries and are produced from the toxic and corrosive gas hydrogen fluoride. A team of chemists have now produced these fluorochemicals without the use of this harmful gas.

Researchers have discovered a 1,000 percent difference in the storage capacity of metal-free, water-based battery electrodes. These batteries are different from lithium-ion batteries that contain cobalt. The group's goal of researching metal-free batteries stems from having better control over the domestic supply chain since cobalt and lithium are outsourced. This safer chemistry would also prevent battery fires.

Niobium-graphene batteries have been developed by the Centre for Advanced 2D Materials at the National University of Singapore and CBMM. Currently being tested at the high-tech CBMM-CA2DM Advanced Battery Laboratory in Singapore, these batteries can be used in various applications such as medical devices, electric vehicles, aerospace equipment, etc.

Ammonium-ion electrolytes could help create ecofriendly and sustainable alternatives to lithium-ion batteries, particularly for grid storage.

Researchers have used crab carbon derived from crab shells to develop anode materials for the next generation of rechargeable batteries i.e. sodium-ion batteries. This work could pave the way for researchers to explore other wastes in order to develop more sustainable solutions.
