This schematic illustrates how atomic-scale Ni catalysts embedded in a porous graphene matrix address key challenges in Li–O₂ batteries. By simultaneously enhancing cathode reaction kinetics and ...

Anode – Typically made of reactive materials like lithium or zinc, the anode undergoes oxidation, releasing electrons. Cathode – A material capable of accepting electrons, the cathode undergoes ...

Each configuration can serve its own purpose depending on the technology it is used for. 3D printed, printed, imprinted and linear Zn anodes are shown. Researchers have proposed a reconfiguration of ...

Cathodes play a dominant role in defining cell energy density, and also make up a significant proportion of cell costs, due to the use of high-cost metals such as cobalt, nickel and lithium. Standard ...

Lithium-ion batteries are the most popular secondary batteries for these applications, and silicon is widely regarded as the best anode material for lithium-ion batteries, particularly solid-state ...

Researchers in Germany have unveiled a low-cost anode that achieved an initial efficiency of ...
