These components contribute to the capacity and energy, electronic conductivity, and mechanical integrity of the electrode.
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).
The peak of Ni 2 p at 831.08 eV is almost inexistence in the SEI on graphite for MEA battery (Supplementary Fig. 19 and Table 9), suggesting the inhibition of nickel dissolution.

The positive electrode plate was cut into round pieces with a diameter of 12 mm, and the mass loading of the active material was about 15 mg cm −2 for the full cell test. The obtained positive electrode sheets were dried overnight in a vacuum oven at 50 °C before assembling.
