MIT researchers invent a battery rechargeable with a liquid

In other words as simple as refueling.

“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.”

Separation of charged and discharged elements makes this new battery 10 times more efficient than the current technologies.

The liquid is called "Cambridge Crude" apart from this picture few information on its origin or recyclability are revealed for the moment.

The “plus” the technology:

-The cost is two times lower than the one of a conventional lithium battery, which would make electric vehicles as competitive as a diesel.
-Prototypes of larger size are being developed and could be fitted in vehicles within 18 months as the innovation is based on two existing and complementary technologies.
-The efficiency the battery can significantly reduce the size and weight.

The technology has been patented by the company 24M Technologies founded last summer by the two professors heading the project Yet-Ming Chiang and W. Craig Carter with the entrepreneur Throop Wilde. The company has already raised more than $ 16 million in private and public funds.

This battery is especially suited for large applications and is a revolution that could give rise to a range of battery (several combinations are being tested).
