IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

The team’s battery chemistry with the solid electrolyte can potentially boost the energy density by as much as four times above lithium-ion batteries, which translates into longer driving range. A lithium-air battery based on lithium oxide (Li 2 O) formation can theoretically deliver an energy density that is comparable to that of gasoline.

New group of materials could lead to faster-charging Li-ion batteries

Green Car Congress

The researchers, led by Professor Clare Grey, found that lithium ions move through the materials at rates that far exceed those of typical electrode materials, which equates to a much faster-charging battery. The maximum power output and minimum charging time of a lithium-ion battery depend on both ionic and electronic transport.

SLAC, MIT, TRI researchers advance machine learning to accelerate battery development; insights on fast-charging

Green Car Congress

Instead of using machine learning just to speed up scientific analysis by looking for patterns in data—as typically done—the researchers combined it with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries.

Faraday Institution launches physics-based battery modeling standard: BPX

Green Car Congress

The Faraday Institution launched the Battery Parameter eXchange (BPX) , an open standard for physics-based lithium-ion battery models. Within the standard, parameters are stored in a human-readable, extensible, and easily-shared JSON file format.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. The researchers focused mainly on the favorable cost-performance comparisons between their sodium-ion battery and lithium. —Lee et al.

Study identifies main culprit behind lithium metal battery failure; counters conventional wisdom

Green Car Congress

They promise twice the energy density of today’s lithium-ion batteries with graphite anodes, so they could last longer and weigh less. As the battery cycles, its stores of active lithium and electrolyte are depleted. Inactive lithium is also made up of another component: lithium ions, which are the building blocks of the SEI layer.
