Two-dimensional porous carbon nanosheets (PCNs) are advanced carbon materials featuring a planar morphology and high porosity. These unique structural characteristics make them ideal as anode materials for next-generation sodium-ion batteries (SIBs). By combining short-range ordered carbon stacking with a long-range disordered framework, PCNs offer a balanced combination of ion transport efficiency, capacity retention, and cycle stability.

Key Features
- Short-range carbon stacking with long-range disorder
The pyrolysis process encourages planar carbon layer growth, but molecular cross-linking restricts long-range order. As a result, the structure comprises amorphous carbon interspersed with randomly stacked nanocrystalline domains, creating internal defects and pores that enhance ion accessibility.
- Large interlayer spacing and high microporosity
Compared with conventional graphite, PCNs feature greater interlayer distances and a higher micropore volume. This allows for more rapid ion intercalation/deintercalation and provides abundant active sites, contributing to higher reversible capacity.
- Excellent rate capability
The open porous framework supports efficient sodium-ion diffusion, enabling fast charging and discharging without significant capacity loss—an important advantage for high-power applications.
The inherent structural stability of hard carbon ensures reliable long-term cycling performance, even under high-rate or extended-use conditions.
Application Areas
- New Energy Vehicles (NEVs): Ideal for use in electric vehicles with moderate endurance demands, sodium-ion batteries incorporating PCNs offer enhanced low-temperature performance, safety, and fast-charging capability.
- Grid-Level Energy Storage: As demand for large-scale storage grows with solar and wind energy deployment, PCNs contribute to longer battery life and improved reliability in stationary energy storage systems.
- Consumer Electronics: Suitable for smartphones, tablets, laptops, and similar devices, thanks to their excellent rate performance and safety characteristics.
- Smart Grid Infrastructure: Enhances energy storage components in smart grids, helping stabilize energy supply, manage load fluctuations, and improve grid efficiency.
- Light Electric Vehicles: Cost-effective and well-suited for electric bicycles, scooters, and tricycles where weight constraints are less critical, and affordability is key.
