Researchers
at Adelaide University have discovered a promising new strategy that could
deliver fast battery charging. The team, led by Professor Shi-Zhang Qiao, an
ARC Industry Laureate Fellow in the University's School of Chemical
Engineering, created pouch battery cells using interfacial anion-reduction
catalysis to record a charge of more than 85% after six minutes. The cells also
provided about 240.4 watt-hours per kilogram after fewer than six minutes of
charging.
Fast charging capabilities are essential
for accelerating the adoption of electric vehicles. Professor Qiao said current
models of high-capacity batteries, like those of silicon and lithium, are fast, but
their capacities fade rapidly.
"Current models also increase heat
generation during fast charging, which can exacerbate battery degradation and
safety risks," Professor Qiao said. "Until now, achieving more than 90% charge within 10 minutes without sacrificing energy
density and cycle life has been a formidable challenge."
Professor Qiao and his team, which
included researchers from Imperial College London, researched the capabilities
of a cell using interfacial anion-reduction catalysis. Their findings are published in the journal Nature
Energy.
"The catalytic sites on the electrode surface attract anions to the
battery interface and promote the formation of a robust inorganic protective
layer, which is critical for fast charging and long-term stability," he
said. "Unlike traditional electrolyte engineering, which often affects the
entire electrolyte system, this strategy regulates reactions only at the
interface, allowing fast charging without sacrificing ionic conductivity."
Professor Qiao said the discovery
provides a new strategy for developing practical fast-charging lithium-ion
batteries. "Our test cell exhibited excellent performance, achieving about
76% capacity retention after 500 six-minute cycles," Professor Qiao said.
"The cells also exhibited excellent stability at 10 minutes of charging.
"The discovery could help enable
electric vehicles that charge in minutes without sacrificing battery life or
energy density."
The team will now focus on scaling up the technology and testing its long-term performance under practical operating conditions.
