Massachusetts Institute of Technology (MIT) scientists have announced what they claim is a “Significant advance in battery architecture [that] could be breakthrough for electric vehicles and grid storage.”    According to a story by David L. Chandler from the MIT News Office, the new battery system is lightweight and inexpensive, and could make recharging “as quick and easy as pumping gas into a conventional car.” Seemingly requiring some active components within the battery, this “semi-solid flow cell” pumps solid particles suspended in a carrier liquid which form the cathodes and anodes through the system.  According to the MIT news item, “These two different suspensions are pumped through systems separated by a filter, such as a thin porous membrane.”  Mechanically more complex than today’s batteries, the system still has a claimed “10-fold improvement over present liquid-flow batteries” (not necessarily that much better than lithium ion, then), but lower manufacturing costs. The different fluids are contained in two different containers and not …
