MIT electrolyte enables ultra-high voltage Ni-rich cathodes in Li-metal batteries

Green Car Congress

Many cathode degradation mechanisms are intensified in LMBs operated under high cut-off voltages, including cathode–electrolyte side reactions, bulk and surface phase transformation, cracking of the NMC secondary particles, over-growth of cathode–electrolyte interphases (CEIs), gas evolution and transition metal (TM) dissolution.

The Net-Zero Neighborhood: Advanced Energy Storage and Highly Efficient Photovoltaics Take Transportation Off the Gasoline Grid and Residential Off the Electric Grid

Green Car Congress

In a special presentation yesterday at the “ Beyond Lithium Ion: Computational Perspectives ” conference held at Argonne National Laboratory, Dr. Gil Weigand of Oak Ridge National Laboratory outlined his vision of a critical solution to the energy, climate and ensuing national security threats facing the US: the Net-Zero Neighborhood (NZN).
