New technique allows recycling components of solid-state batteries over and over again

“Defects in batteries, such as voids and cracks caused by mechanical stress on the solid-state electrolytes, may block lithium-ion transport pathways and lead the battery to short circuit,” said Yi-Chen Lan, doctoral student in chemical engineering and first author on a paper explaining the recent findings and published in the journal ChemSusChem. “To recycle electrolytes that have undergone mechanical degradation, we use cold sintering to re-densify the microstructures and reprocess composite electrolytes by mixing ceramics with polymers and lithium salts.” The idea for cold sintering the liquid electrolytes needed in solid-state batteries came about in 2018, when a postdoctoral scholar

The Innovation of Non-Flammable Electrolytes in Lithium-Metal Batteries

Research and Development of a Groundbreaking Solution Improving the stability of high-voltage chloride-based solid electrolytes (Li3MCl6) has been a long-standing challenge for researchers in the field. A recent breakthrough by a collaborative team has proposed a revolutionary design principle – a chloride-based solid electrolyte (Li3MCl5F) incorporating fluorine (F), known for its robust chemical bonding capabilities. By leveraging the supercomputing resources at LLNL for precise calculations and conducting experimental validations at KIST, this innovative approach marks a turning point in battery technology. The strategic alliance adopted a cost-effective and time-efficient method, where computational simulations guided the initial material design, followed by

The Rise of LFP Batteries Reshapes the Electric Vehicle Market

In early 2023, it appeared that cobalt and nickel-laden electric car battery markets were dealt a colossal blow, altering the balance of power in the industry. A few months later, the burgeoning success of LFP Model 3 stood as a testament to a significant shift in the global EV market, with LFP technology claiming an impressive 5% share and accounting for 21% of Tesla’s battery capacity in vehicles on the road, even before a critical patent expiry set for the following year. Shifting Dynamics in the Market It’s January 2024 and unfortunately for the staunch advocates of cobalt and nickel,
