Lamborghini licenses MIT’s Cobalt-free organic battery tech for EVs – ET Auto

Baua Electric

Cobalt extraction creates hazardous working conditions and generates toxic waste that contaminates land, air, and water surrounding the mines. Dinca and his team plan to continue developing alternative battery materials and is exploring possible replacement of lithium with sodium or magnesium, which are cheaper and more abundant than lithium.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. Sodium-ion based rechargeable batteries (SIBs, e.g., earlier post ) are of interest due to sodium’s abundance, far lower prices, and a greener synthesis while maintaining a similarity in ion-insertion chemistry.

Vanderbilt/ORNL team discovers new form of crystalline order that could be attractive for thermoelectric applications

Green Car Congress

If you put a pair of sodium and chlorine atoms at each lattice point, they form sodium and chlorine sub-lattices and you get salt. Materials Thermoelectrics Waste Heat Recovery' When you have more than one atom at each point, each type of atom forms its own sub-lattice. CIS is a bit more complicated.

for the materials and possibly good enough for consideration for waste heat recovery in automotive exhaust systems. The high thermoelectric figure of merit is expected to enable the conversion of 14% of heat waste to electricity. Articles ASAP doi: 10.1021/nl104138t. The study by Yan et al.

Polymer microcapsules with liquid carbonate cores and silicone shells offer a new approach to carbon capture

Green Car Congress

The new technique employs an abundant and environmentally benign sorbent: sodium carbonate (the main ingredient in baking soda). These permeable silicone beads could be a “sliced-bread” breakthrough for CO 2 capture—efficient, easy-to-handle, minimal waste, and cheap to make. Satcher Jr., Bourcier, Christopher M. Lewis & Roger D.

lithium-iron phosphate , lithium-ion phosphate , lithium-sulfur , lithium-metal , and sodium-ion among many others , not to mention solid-state batteries , as a way to alleviate some of the material supply and cost problems. In the next article in the series, we will look at whether the grid can handle tens of millions of EVs.
