Li, art )-
The ion battery is approaching its specific energy limit, but is challenged as never before
The demand for today's energy storage and power applications is growing, especially for electric vehicles.
Li metal is considered a high-end anode material in the future
When combined with existing or emerging high-powered rechargeable batteries
Cathode material of capacity.
However, the current research focuses mainly on the level of battery material, and there is little description of the principle of battery design.
Here we discuss the specific energy required for the key conditions is higher than 350 W kg −1, up to 500 W kg −1, and the rechargeable lithium metal battery uses highnickel-
Lithium nickel manganese cobalt oxide as cathode material.
We also provide analysis of key factors affecting the battery, such as cathode load, electrolytic mass and Li foil thickness
Level cycle life.
In addition, we identified several important strategies for reducing electrolyte
Li reaction, protecting Li surface, stabilizing anode structurecycling high-specific-energy cells.
