Total has signed a research agreement with the Massachusetts Institute of Technology (MIT) to develop new stationary batteries that are designed to enable the storage of solar power. This agreement valued at $4 million over five years is part of the MIT Energy Initiative (MITEI), which Total joined as a member in November 2008.
Chemists at the University of Waterloo have identified the key reaction that takes place in sodium-air batteries. Understanding how sodium-oxygen batteries work has implications for developing the more powerful lithium-oxygen battery, which has been proposed by some as the “holy grail” of electrochemical energy storage.
A new metal mesh membrane developed by researchers at MIT could advance the use of the Na–NiCl 2 displacement battery, which has eluded widespread adoption owing to the fragility of the ?"-Al through the MIT Energy Initiative. Al 2 O 3 membrane. A paper describing the development is published in the journal Nature Energy.
MIT professor Donald Sadoway and his team have demonstrated a long-cycle-life calcium-metal-based liquid-metal rechargeable battery for grid-scale energy storage, overcoming the problems that have precluded the use of the element: its high melting temperature, high reactivity and unfavorably high solubility in molten salts.

It’s been known that dendrites form more rapidly when the current flow is higher—which is generally desirable in order to allow rapid charging. At the ordinary temperatures that the battery operates in, “it stays in a regime where you have both a solid phase and a liquid phase,” in this case made of a mixture of sodium and potassium.
Researchers led by a team from MIT, with colleagues from Oak Ridge National Laboratory (ORNL), BMW Group, and Tokyo Institute of Technology have developed a fundamentally new approach to alter ion mobility and stability against oxidation of lithium ion conductors—a key component of rechargeable batteries—using lattice dynamics.
A collaboration including researchers from Boston College, MIT, the University of Virginia and Clemson University have achieved a peak ZT (thermoelectric figure of merit) of 0.8 Two separate research collaborations have recently reported advances in the efficiency of thermoelectric materials in converting heat to electricity. at ~800 K.
The research, published in Nature , was conducted by a team of scientists affiliated with the MIT-Harvard Center for Ultracold Atoms and MIT’s Research Laboratory of Electronics. In a magnified part of the image, the MIT researchers found a number of these little hole-like patterns, chained together in regularly repeating fashion.
Magnesium offers a number of advantages over lithium: it is safer and earth-abundant, and doubles the total charge per ion, delivering larger theoretical volumetric capacity compared with a typical lithium-ion battery. —Gerbrand Ceder, a Berkeley Lab Senior Faculty Scientist. —Canepa et al.
The new battery also has comparable storage capacity and can be charged up faster than cobalt batteries. Researchers from Massachusetts Institute of Technology ( MIT ), including one of Indian-origin, have designed a new battery material that could offer a more sustainable, cobalt-free way to power electric cars.
Researchers at the Skoltech Center for Electrochemical Energy Storage (CEES), a partnership between the MIT Materials Processing Center and Lomonosov Moscow State University, are focusing on the development of higher capacity batteries. Chiang, MIT colleague W. Advanced Li-ion and multivalent ion batteries.
When the battery is charged, the chemical process reverses, returning the electrodes to their original state—almost. Its lab tests revealed that most were variations of salt mixtures, such as sodium and magnesium sulfates. Although the additives might help the battery charge faster, they didn’t extend battery life.
