New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

The results could make possible a whole family of inexpensive and durable materials practical for large-scale rechargeable batteries. The use of the new type of membrane can be applied to a wide variety of molten-electrode battery chemistries, Sadoway said, and opens up new avenues for battery design.

This Startup Builds USVs That Collect Data About Oceans

Cars That Think

This spurred Julie Angus to cofound the startup Open Ocean Robotics to design, build, and operate oceangoing uncrewed surface vehicle (USV) drones. The company designs and builds the drone’s hull, deck, and circuit boards. Our boats can operate and travel nonstop for months, without needing refueling or external recharging.”

New Li-S battery shows cycle performance comparable to that of Li-ion batteries along with more than double the energy density

Green Car Congress

The team, led by a group from Hanyang University, used a highly reversible dual-type sulfur cathode (solid sulfur electrode and polysulfide catholyte) and a lithiated Si/SiO x nanosphere anode. sulfur battery system adopting alloy-type anode materials needs to be advanced further before they can penetrate the rechargeable battery market.

Greenlings: Benefits of charging stations vs. battery swaps vs. home charging

Tony Karrer Delicious EVdriven

Please feel free to tell us what you believe to be the benefits of some of the various recharging modes mentioned above in the comments section below. Obviously, with replaceable battery packs, they can both be charged at the optimal time and always be hanging around to serve as valuable electrical power storage for the grid.
