Seaweed-Based Battery Powers Confidence in Sustainable Energy Storage

CleanTechnica EVs

Bristol-led team uses nanomaterials made from seaweed to create a strong battery separator, paving the way for greener and more efficient energy storage. Sodium-metal batteries (SMBs) are one of the most promising high-energy and low-cost energy storage systems for the next-generation of large-scale applications.

CMU study concludes lithium market fluctuations unlikely to impact Li-ion battery prices significantly

Green Car Congress

The study comes against the backdrop of a more than doubling of global lithium prices over the last 6 months. They found that the use of more expensive lithium precursor materials results in less than 1% increases in the cost of lithium-ion cells considered.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. The five battery technologies fared much worse. Lithium-ion batteries were the best performers, with an ESOI value of 10.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

To maximize the benefit of the open structure, the researchers needed to use ions that fit; hydrated potassium ions proved to be a much better fit compared with other hydrated ions such as sodium and lithium. Potassium will just zoom in and zoom out, so you can have an extremely high-power battery.

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

A team at the Ohio State University has developed a membrane that regulates bi-directional ion transport across it as a function of its redox state and that could be used as a programmable smart membrane separator in future supercapacitors and redox flow batteries.
