Black phosphorus electrochemical energy storage mechanism

Can black phosphorus be used for energy storage?

Black phosphorus is a potential candidate material for next-generation energy storage devices and has attracted tremendous interest because of its advantageous structural and electrochemical properties, including its large theoretical capacity, high carrier mobility, and low redox potential.

What is black phosphorus?

Black phosphorus (BP) is a type of relatively novel and promising material with some outstanding properties, such as its theoretical specific capacity (2596 mAh/g) being approximately seven times larger than that of graphite as a negative material for batteries. Phosphorene, a one-layer or several-layer BP, is a type of two-dimensional material.

What are the applications of black phosphorus?

This review specifically highlights the very recent progress in the synthesis and applications of black phosphorus in the energy process, including secondary battery system, supercapacitor device, and catalysis reaction.

Could black phosphorus open a new chapter for energy materials?

All in all, with persistent attempts by researchers around the world, it is out of question that black phosphorus would not only open a new chapter for a new generation of energy materials but also provide a remarkable market potential in the foreseeable future. There are no conflicts to declare.

What is the specific capacity of black phosphorus?

In particular, black phosphorus has a folded structure, and each P atom can react with three Li or Na atoms to form Li 3 P and Na 3 P, giving it a very high theoretical specific capacity of 2596 mAh/g [ 31 ], which is far more than the graphite negative electrode (372 mAh/g) with its excellent energy storage properties.

Is black phosphorus a lithium ion lithiation material?

Black phosphorus (BP), as a typical two-dimensional material, exhibits excellent lithium ion lithiation/delithiation properties when used in lithium-ion battery energy storage processes, primarily relying on the intercalation mechanism .
