  Chinese scientists ,drops new Lithium battery with cell lifespan upto 9000 hours

After multiple lithium battery failures or incidents reported, Chinese scientists have developed a new battery system that could enable lithium cells to operate safely for thousands of hours.

The Independent reports that Chinese researchers had found the reason for lithium battery failures and new research findings from Chinese scientists promise long-lasting Lithium batteries for real-world applications. Advertisement

Lithium metal batteries have become the cornerstone for future power systems due to their high energy storage capacity.

However, the current liquid electrolytes in these cells pose several risks, including leakage and combustion and growth of lithium metal inside batteries into needle-like or branch-like structures during charging which compromises battery safety and performance.   Chinese researchers drops new Lithium battery with cell lifespan upto 9000 hours

The study, published in the Journal of the American Chemical Society, reveals that researchers had introduced a new class of electrolytes known as “deep eutectic gel electrolytes （DEGEs）“ made with fluorinated amides which can help solve the failure issues due to their high charge conduction capacity and inherent thermal stability.

“We developed a series of DEGEs utilizing fluorinated amides, which leverage the electron-withdrawing effects of fluorine,” researchers wrote.

Chinese scientists believe that these materials may help prevent leakage, overheating, and the formation of dangerous needle-like lithium structures that often compromise battery safety and lifespan.

“By introducing fluorinated groups into DEGEs, we achieved not only enhanced interfacial stability but also markedly improved cycling durability and thermal safety,” Dr Liu said.

Moreover, Scientists found that batteries with new electrolytes based on 2,2,2-trifluoro-N-methylacetamide, cycled stably for over 9,000 hours and retained more than 80% capacity after 2,500 charge cycles.  

They further explained that even at temperatures up to 80°C, they maintained performance for 300 cycles.   Chinese scientists promise new Lithium batteries will be safer and long-lasting for real-world applications

Researchers also found that batteries built with new electrolytes enabled a compact battery system that also show promising results in suppressing the formation of the needle-like lithium branches.

“Our study demonstrates how precise molecular design can simultaneously tackle multiple challenges in lithium metal battery development,” said Tianfei Liu, an author of the study from Nankai University in China.

Additionally, the overall findings suggest fluorination and an electrolyte gel confinement system within lithium cells can help overcome the long-standing limitations of these batteries.

The results of this advanced development could present a promising way to scale up lithium batteries for real-world applications such as electric vehicles and power grids at larger scale.

“This strategy bridges fundamental chemistry with real-world performance requirements, offering a blueprint for the next generation of high-performance electrolyte design,” said Kai Zhang, another author of the study published in Journal of the American Chemical Society.
