  • New ion speed record holds potential for faster battery charging, biosensing

    Updated: 2024-11-19 18:35:04
    A speed record has been broken using nanoscience, which could lead to a host of new advances, including improved battery charging, biosensing, soft robotics and neuromorphic computing. Scientists have discovered a way to make ions move more than ten times faster in mixed organic ion-electronic conductors. These conductors combine the advantages of the ion signaling used by many biological systems, including the human body, with the electron signaling used by computers. The new development speeds up ion movement in these conductors by using molecules that attract and concentrate ions into a separate nanochannel creating a type of tiny 'ion superhighway.'

  • Battery research with X-ray microscope

    Updated: 2024-11-19 18:27:06
    New cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometer scale and also clarify chemical changes.

  • Recycling batteries with citric acid

    Updated: 2024-11-15 05:47:31
    A simple, highly efficient, inexpensive, and environmentally friendly process could provide a viable pathway for the sustainable recycling of depleted lithium-ion batteries (LIBs): No chemicals beyond citric acid need to be added to leach out and separate over 99 % of the lithium, nickel, cobalt, and manganese metals contained in NCM batteries. The resulting recycled material can be directly converted into NCM electrodes, reports a research team.

  • Leveraging machine learning to find promising compositions for sodium-ion batteries

    Updated: 2024-11-05 16:36:55
    Sodium-containing transition-metal layered oxides are promising electrode materials for sodium-ion batteries, a potential alternative to lithium-ion batteries. However, the vast number of possible elemental compositions for their electrodes makes identifying optimal compositions challenging. In a recent study, researchers leveraged extensive experimental data and machine learning to predict the optimal composition of sodium-ion batteries. Their approach could help reduce time and resources needed during exploratory research, speeding up the transition to renewable energy.
