High-efficiency electrodes with ultralight current collectors
Eight industrial and scientific entities in Germany have come together to pursue two key innovations in lithium-ion battery technology: the replacement of metal foils with a metallized fabric structure, and the use of silicon as anode material.
Novel oxygen-ion battery may offer longer lifespan, claims TU Wien
Austrian scientists have created a lab-scale, solid-state, oxygen ion battery based on mixed ionic electronic conducting (MIEC), which is a special class of non-flammable electroceramic materials. The battery has around 30% of the energy density of lithium-ion batteries but can purportedly achieve a longer lifespan.
New polymer electrolyte for lithium-metal batteries
Researchers at the University of Hong Kong have discovered a series of anionic network solid electrolytes that can deliver at least a fourfold improvement in cationic transport for lithium-metal battery applications.
Weekend Read: Light weight
When it comes to gravity batteries, pumped-hydro storage is the gold standard, but its cost and topography-specific limitations are driving innovations ranging from freight-train braking to super-dense liquids. We consider whether any of the new technologies can punch above their weight.
Weekend Read: A long time coming
Long-duration energy storage (LDES) is essential for decarbonizing the grid but gigawatt-hour scale systems continue to be tricky for companies with big ideas. Here are some of the latest innovations across a flourishing array of new – and old – ideas.
Custom-made 3D printed solid-state batteries
US-based Sakuu has announced that it has successfully 3D printed solid-state batteries in custom shapes and sizes at its battery pilot line facility in Silicon Valley, California.
How safe are second-life EV batteries as home energy storage devices?
There is currently no widely accepted test methodology to assess the safety of second-life lithium-ion batteries (LiBs). However, a UK government study reveals two opposing views on their safety, raising concerns over whether such devices should be deployed in homes under any circumstances.
Vanadium’s role in a just transition
The deployment of a vanadium flow battery at a fire station run by Native Americans illustrates the role that the energy storage technology can play in ensuring that nobody is disadvantaged by the shift away from fossil fuels.
US startup unveils portable solid-state lithium-ion battery for residential use
California-based Yoshino Technology has developed portable batteries using solid-state Li-NCM cell technology. The four variants come with power outputs of 330 W, 660 W, 2,000 W, and 4,000 W.
Lithium-vanadium battery for renewables storage
AMG Advanced Metallurgical Group has energized its first hybrid storage system based on lithium-ion batteries and vanadium redox flow batteries in Germany. The system reportedly combines the advantages and electrochemical properties of both storage technologies.
