AIST Developing New Lithium-Air Battery; Lithium Fuel Cell

Green Car Congress

Long-term discharge curve of the newly developed lithium-air cell. Researchers at Japan’s AIST (National Institute of Advanced Industrial Science and Technology) are developing a lithium-air cell with a new structure (a set of three different electrolytes) to avoid degradation and performance problems of conventional lithium-air cells.

PNNL team uncovers reaction mechanisms of Li-air batteries; how batteries blow bubbles

Green Car Congress

Lithium-air batteries are looked to by many as a very high-energy density next-generation energy storage solution for electric vehicles. One reaction that hasn’t been fully explained is how oxygen blows bubbles inside a lithium-air battery when it discharges. Oxygen gas is released and inflates the bubble.

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.
