The study could aid in enhancing current battery materials and accelerate the development of next-generation batteries.Researchers have discovered that the performance and capacity of next-generation battery materials may be hampered by the irregular movement of lithium ions. The team, which was led by the, monitored the flow of lithium ions in real time inside a prospective new battery material.
The Faraday Institution-funded study might contribute to the advancement of existing battery materials and hasten the creation of next-generation batteries. The findings were recently published in the journalIn order to shift to a zero-carbon economy, electrical vehicles are essential. Because of its great energy density, lithium-ion batteries power the majority of electric vehicles currently on the road.
“This is the first time that this non-uniformity in lithium storage has been directly observed in individual particles,” said co-first author Alice Merryweather, from Cambridge’s Yusuf Hamied Department of Chemistry. “Real-time techniques like ours are essential to capture this while the battery is cycling.”
Importantly, the lithium heterogeneity seen at the end of discharge establishes one reason why nickel-rich cathode materials typically lose around ten percent of their capacity after the first charge-discharge cycle.
