Macroporous Interconnected Hollow Carbon Nanofibers Inspired by Golden‐Toad Eggs toward a Binder‐Free, High‐Rate, and Flexible Electrode

Inspired by the favorable structure and shape of golden-toad eggs, a self-standing macroporous active carbon fiber electrode is designed and fabricated via a facile and scalable strategy. After being decorated with ruthenium oxide, it endows Li-O2 batteries with superior electrochemical performances.

A Flexible and Wearable Lithium-Oxygen Battery with Record Energy Density achieved by the Interlaced Architecture inspired by Bamboo Slips.

A flexible and wearable lithium-oxygen (air) battery inspired by Chinese bamboo slips is constructed. In this novel battery, cathodes and anodes are woven without an air diffusion layer and any outer packaging; besides, the woven structure allows oxygen to access the cathodes from both sides freely, endowing the battery with a record energy density of over 523 W h kg-1 .

Flexible and Foldable Li–O2 Battery Based on Paper-Ink Cathode

A flexible freestanding air cathode inspired by traditional Chinese calligraphy art is built. When this novel electrode is employed as both a new concept cathode and current collector, to replace conventional rigid and bulky counterparts, a highly flexible and foldable Li-O2 battery with excellent mechanical strength and superior electrochemical performance is obtained.

Cable‐Type Water‐Survivable Flexible Li‐O2 Battery

A novel cable-type water-survivable flexible Li-O2 battery is developed with a hydrophobic and free standing gel polymer electrolyte. Superior battery performances are successfully achieved under mechanical twisting, bending, and even immersed in water conditions, showing the high promise to power next-generation versatile flexible electronics.

Hierarchical Co3O4 porous nanowires as an efficient bifunctional cathode catalyst for long life Li-O2 batteries

Hierarchical Co3O4 porous nanowires (NWs) have been synthesized using a hydrothermal method followed by calcination. When employed as a cathode catalyst in non-aqueous Li-oxygen batteries, the Co3O4 NWs effectively improve both the round-trip efficiency and cycling stability, which can be attributed to the high catalytic activities of Co3O4 NWs for the oxygen reduction reaction and the oxygen evolution reaction during discharge and charge processes, respectively.
