Performance of Phosphorus Storage Lithium Batteries

Why is phosphorus a promising anode material for fast-charging lithium-ion batteries?

Phosphorus is a promising anode material for fast-charging in lithium-ion batteries because of the combined advantages of high theoretical mass and volume specific capacity as well as a relatively low, yet safe lithiation potential to avoid Li metal dendrite formation.

Is phosphorus a good anode material for lithium ion batteries?

Phosphorus is an ideal anode material for high-rate lithium-ion batteries due to its high theoretical specific capacity and moderate operating potential. However, phosphorus undergoes tremendous volume expansion and low electrical conductivity during lithium storage, affecting its actual lithium storage performance.

Can phosphorus oxidation improve battery performance?

Moderately controlling the oxidation of phosphorus anodes to form a uniform surface coating could improve battery performance while maintaining stability and safety. Phosphorus oxidation is an irreversible process that profoundly affects the performance of phosphorus-based anode in batteries.

How does phosphorus affect lithium storage performance?

However, phosphorus undergoes tremendous volume expansion and low electrical conductivity during lithium storage, affecting its actual lithium storage performance. The formation of P–C bonds is an effective strategy to inhibit the volume expansion and maintain stable electrical contact between phosphorus and the current collector.

How can phosphorus-based high-capacity alloy anodes improve battery life?

Thus, establishing a stable and flexible SEI layer is crucial for extending battery life and preserving the high capacity of phosphorus-based high-capacity alloy anodes. Initially, the modification of the anode surface can strategically control SEI formation.

Is black phosphorene a promising anode for lithium-ion and sodium ion batteries?
