# Correction: 3D-engineered WO3 microspheres assembled by 2D nanosheets with superior sodium storage capacity

## TL;DR

This paper corrects a previous study on engineered tungsten oxide microspheres for better sodium storage in batteries.

## Contribution

The correction addresses errors in the original paper on sodium storage capacity of 3D-engineered WO3 microspheres.

## Key findings

- The original study's sodium storage capacity data was inaccurate.
- The correction provides updated experimental details and revised results.
- The revised findings confirm the potential of WO3 microspheres for sodium-ion batteries.
