Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. A paper on the work is published in Nature. —Pang et al. —Donald Sadoway.

There’s another benefit to this battery, and this one will make EV drivers very happy: It will take only 10 minutes to reach an 80 percent charge in EVs powered by these batteries, Rustomji estimates. The rare earth oxide then undergoes a molten-salt electrolysis process that converts it into a solid metal form.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

Batteries that can hold large amounts of energy are large and expensive, requiring a substantial investment to install. Energy storage has two main factors—how fast it can be charged and discharged (the spigot) and how much total energy it can hold (the bathtub). But Liu says residential customers don’t see demand charges.

This Fusion Reactor Is Held Together With Tape

Cars That Think

Gretchen Ertl/CFS/MIT Plasma Science and Fusion Center What sets CFS’s technology apart is its use of high-temperature superconducting tape, which is layered and stacked to create extremely strong electromagnets that will shape and confine the unruly plasma and keep the bulk of the charged particles away from the tokamak’s walls.

What is Home energy management system, why it is needed

Baua Electric

A smart meter is a digital device that records and monitors the consumption of electricity, gas, or water in a home or business. Because they usually sit for a long period of time, their charging can be shifted to periods when either solar generation is high or electricity prices are low.

California Energy Commission awards more than $5.5M for green transportation projects and $1.8M for 20 energy research projects

Green Car Congress

Each system comprises electronic components that can be used with a variety of batteries and motors and installed on conventional medium- and heavy-duty chassis, modifying them into all-electric battery operated vehicles that have no tailpipe emissions. Currently, these powertrains are primarily installed in shuttle buses and delivery trucks.
