Electrode Materials for Rechargeable Lithium and Sodium-Ion Batteries

Rechargeable lithium-ion and sodium-ion batteries underpin modern portable electronics, electric vehicles and grid storage, yet their widespread adoption hinges on continual improvements in electrode design. Conventional graphite anodes in lithium-ion systems offer reliable intercalation but face limitations in capacity and rate performance. Layered transition-metal oxides and polyanionic cathodes deliver high voltage and energy density, yet their cycle life and resource constraints prompt exploration of alternatives. Sodium-ion batteries, benefiting from abundant and low-cost sodium sources, pursue hard carbons, layered oxides and conversion-type metal compounds to approach lithium-type performance. Nanostructuring, pore engineering and heteroatom doping emerge as unifying strategies to boost ion transport, electronic conductivity and structural stability. The global imperative for sustainable energy storage drives research towards scalable synthesis, binder-free architectures and electrode–electrolyte integration, ensuring safety, cost-effectiveness and long cycle life.

Research from Nature Portfolio

Innovative three-dimensional inverse opal structures of ternary Ni–Mn–Co oxide have been developed as conversion-type anodes for lithium-ion cells. These materials employ a honeycomb framework that converts into nanoscale oxides during cycling, while a thin carbon coating preserves open pore channels for efficient lithium diffusion and electrolyte penetration. Such electrodes exhibit significantly enhanced specific capacity and retention compared with bulk analogues, and demonstrate high-rate performance when coupled with tailored electrolyte additives. In a complementary approach, metal–organic-framework-derived porous carbon has been synthesised with multifractal pore networks, achieving ultrahigh lithium storage capacity and excellent rate capability. Detailed scattering studies reveal that closed-pore domains and hierarchical connectivity synergistically govern ion storage, pointing the way towards carbon architectures that rival or exceed traditional graphite performance.
