Huazhong Agricultural University Develops New Lithium Cathode Technology

The high energy density of lithium metal batteries is expected to be the electrochemical storage device for electric vehicles," said a professor at Huazhong Agricultural University. However, the problems of lithium dendrite growth and large volume variation of lithium cathodes have hampered their practical application. It is important to explore suitable methods to solve the problems of lithium cathode to improve the practicality of the battery." 

To address these issues, the researchers created 3D scaffolds with lithium-friendly materials and conducted rigorous tests to maintain 98.6% efficiency after 100 charging cycles.

Looking ahead, the researchers plan to continue improving lithium metal batteries by preparing a composite lithium cathode with a high safety profile that will increase market competitiveness.
