A self-supported sodiophilic 3D Enteromorpha prolifera-derived carbon matrix enables dendrite-free sodium metal anodes

Key Points

• Sodium metal anodes achieved dendrite-free performance with a specially designed carbon matrix.
• The carbon matrix, derived from Enteromorpha prolifera, enhances sodium ion storage capacity significantly.
• Electrochemical testing revealed substantial improvements in cycling stability and efficiency over traditional materials.
• These findings support the feasibility of sustainable and efficient sodium metal anodes for battery technology.
