Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes.
Fortress Power’s Avalon High Voltage Energy Storage System combines a hybrid inverter, high-voltage battery, and a smart energy panel in an all-in-one, whole-home backup system.
U.S.-based Acculon Energy has announced series production of its sodium-ion battery modules and packs for mobility and stationary energy storage applications. Scaled production of 2 GWh is scheduled to start in mid-2024.
The U.S. Department of Energy’s Argonne National Laboratory and Idaho National Laboratory will carry out demonstration projects to validate long-duration energy storage tech developed by German manufacturer CMBlu Energy. The collaborative project is designed to improve microgrids in cold climates and make fast charging of electric vehicles more affordable in underserved communities.
Fourth Power, backed by Bill Gates’ venture firm, has developed high-density thermal energy storage based on thermophotovoltaic cells. The tech, which is reportedly 10 times cheaper than lithium-ion batteries, is based on the U.S. company’s patented liquid metal heat transfer system.
Transformer shortages are taking their toll on battery energy storage system (BESS) integrators, as competition in the market intensifies.
Energy storage with more than four hours of duration could assume a key role in integrating renewable energy into the U.S. power grid on the back of a potential shift to net winter demand peaks, says the National Renewable Energy Laboratory (NREL).
Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.
The Massachusetts Institute of Technology (MIT) has developed a scalable bulk energy storage solution with chemical with inexpensive, abundant precursors: cement, water, and carbon black. Their supercapacitors have high storage capacity, high-rate charge-discharge capabilities, and structural strength.
Georgia Institute of Technology researchers used aluminum foil-based negative electrodes with engineered microstructures in an all-solid-state lithium-ion cell configuration. They have reported hundreds of stable cycles with practically relevant areal capacities at high current densities.
