Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Electrochemical test data revealed when the second sintering temperature is 800℃ material has good electrochemical properties, at 0.5C & 2C, the maximum discharge capacity were 200.2 mAh/g & 145.0 mAh/g, the retention rate of capacity were 85.11% and 88.21% respectively.
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.
On the contrary, the sample structure with more rounded spheres and more uniform secondary particles at a sintering temperature of 800℃ increases the contact efficiency between the electrode and the electrolyte, which is more favorable to electrochemical reactions and therefore easier to transfer lithium ions than the other two samples. 4.
In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
In this work, Li 1.2 Mn 0.54 Ni 0.13 Co 0.13 O 2, a lithium-rich manganese-based cathode material, was successfully prepared using an improved co-precipitation method with acetate as the system. The effect of sintering temperature on its properties was studied systematically in multiple ways.
