Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. In such a device, two liquids are pumped through a channel, undergoing electrochemical reactions between two electrodes to store or release energy. Credit: Braff et al. Click to enlarge.

RPI researchers develop safe, long-cycling Li-metal rechargeable battery electrode; demonstrate Li-carbon battery

Green Car Congress

Researchers at Rensselaer Polytechnic Institute have developed a safe, extended cycling lithium-metal electrode for rechargeable Li-ion batteries by entrapping lithium metal within a porous graphene network (Li-PGN). What is different is that the electrode material that stores the Li is all-carbon for both the anode as well as the cathode.

MIT Researchers Develop Lithium Iron Phosphate Material with Charge/Discharge Rates Comparable to Supercapacitors

Green Car Congress

Researchers at MIT have developed a lithium iron phosphate electrode material that achieves ultra-high discharge rates comparable to those of supercapacitors, while maintaining the high energy density characteristic of lithium-ion batteries. Full charge–discharge cycles at constant 197C and 397C current rates without holding the voltage.

MIT and Harvard team develop material that stores sun’s heat

Green Car Congress

Researchers from MIT and Harvard University have developed a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand. In effect, they behave as rechargeable thermal batteries: taking in energy from the sun, storing it indefinitely, and then releasing it on demand.
