AI extends EV battery life by 23% without slowing down fast charging

Researchers trained a reinforcement learning model on battery electrochemistry to adapt charging current to each battery's state of health

19-May-2026 - Fast charging shortens the life of vehicle batteries, but is necessary on longer journeys with electric vehicles. Researchers at Chalmers University of Technology, Sweden, have now developed a new AI method that adapts fast charging to the health of the battery. Their study shows that battery ...

How intrinsic oxygen shortens the lifespan of solid-state batteries

New method makes degradation visible

12-May-2026 - Although solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special ...

Invisible battery parts finally seen with pioneering technique

New method reveals critical weaknesses in battery electrodes

24-Feb-2026 - Researchers at the University of Oxford have developed a powerful new method to visualise an essential lithium-ion battery electrode component that had been extremely difficult to trace before. The discovery, published in Nature Communications, could lead to increased manufacturing efficiency of ...

Transform plant waste into next-generation safe batteries

Plant-based hydrogel tames zinc dendrites, pushes aqueous batteries past 1 000 stable cycles

14-Jan-2026 - Aqueous zinc-ion batteries promise safe, low-cost energy storage, but metallic zinc grows needle-like dendrites that short-circuit cells within a few hundred cycles. Now, a purely plant-derived hydrogel appears to solve the problem without resorting to toxic additives or expensive ceramics. The ...

Breakthrough in carbon-based battery materials improves safety, durability, and power

05-Jan-2026 - This research demonstrates a new way to make carbon-based battery materials much safer, longer lasting, and more powerful by fundamentally redesigning how fullerene molecules are connected. Today's lithium-ion batteries rely mainly on graphite, which limits fast-charging speed and poses safety ...

Anode-free battery doubles electric vehicle driving range

“This work represents a meaningful breakthrough...”

02-Jan-2026 - Could an electric vehicle travel from Seoul to Busan and back on a single charge? Could drivers stop worrying about battery performance even in winter? A Korean research team has taken a major step toward answering these questions by developing an anode-free lithium metal battery that can deliver ...

Weaving secondary battery electrodes with fibers and tying them like ropes for both durability and performance

09-Dec-2025 - A joint research team led by Dr. Gyujin Song of the Korea Institute of Energy Research (President: Yi, Chang-Keun, hereafter “KIER”), Dr. Kwon-Hyung Lee of the University of Cambridge, and Professor Tae-Hee Kim of the University of Ulsan has successfully developed a new dry-process manufacturing ...

KAIST unveils cause of performance degradation in electric vehicle high-nickel batteries

08-Dec-2025 - High-nickel batteries, which are high-energy lithium-ion batteries primarily used in electric vehicles, offer high energy density but suffer from rapid performance degradation. A research team from KAIST has, for the first time globally, identified the fundamental cause of the rapid deterioration ...

Porous Radical Organic framework improves lithium-sulphur batteries

Significant improvement in service life - Combination of experiments

17-Sep-2025 - A team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent ...

Engineers discover key barrier to longer-lasting batteries

University of Texas at Dallas researchers have discovered why LiNiO2 batteries break down

20-Feb-2025 - Lithium nickel oxide (LiNiO2) has emerged as a potential new material to power next-generation, longer-lasting lithium-ion batteries. Commercialization of the material, however, has stalled because it degrades after repeated charging. University of Texas at Dallas researchers have discovered why ...
