See the vial? That’s Cambridge crude. The crude is a mix of anode and cathode parts that, when poured into an EV’s tank, can run the car. Innovation! The significance of the vial pictured south is it could transform the battery industry and lead to more efficient electric vehicles. Imagine pumping this stuff the ay you pump gas, except there are no emissions.
A little explanatory helpfulness:
The new battery relies on an innovative architecture called a semi-solid flow cell, in which solid particles are suspended in a carrier liquid and pumped through the system. In this design, the battery’s active components — the positive and negative electrodes, or cathodes and anodes — are composed of particles suspended in a liquid electrolyte. These two different suspensions are pumped through systems separated by a filter, such as a thin porous membrane.
The work was carried out by Mihai Duduta ’10 and graduate student Bryan Ho, under the leadership of professors of materials science W. Craig Carter and Yet-Ming Chiang. It is described in a paper published May 20 in the journal Advanced Energy Materials. The paper was co-authored by visiting research scientist Pimpa Limthongkul ’02, postdoc Vanessa Wood ’10 and graduate student Victor Brunini ’08.
Oh yes, the paper mentioned in the quoted text. Here it is.
