Lithium-ion or otherwise, batteries keep lots of things going, and enable a mobile lifestyle: from mobile phones to intercontinental air travel. Batteries are complex devices whose overall performance and usefulness depend on many factors such as energy density, efficiency, durability, and sustainability. Research in this area is by nature interdisciplinary and involves chemists, physicists, materials scientists, and engineers.

Ultrathin MnO2/graphene oxide/carbon nanotube (G/M@CNT) sandwiched interlayer with synergetic effects of graphene oxide sheets, MnO2 nanoparticles, and superaligned carbon nanotube films, significantly alleviates polysulfide shuttling and improves the cycling stability and rate performance of Li–S batteries. Self-discharge and passivation layer formation on the anode are greatly suppressed by the excellent polysulfide-trapping ability of the G/M@CNT interlayer.

Soft cations catalyze the ORR at less negative onset potentials, whereas hard cations hamper the ORR and result in more negative onset potentials.

Its success stems from the unique 2D planar packing of lawsone molecules, displaying a high discharge capacity of 280 mA h g−1 (99% theoretical capacity), a high energy density of 664 W h kg−1, and long life of 1000 cycles at 0.5 C along with good rate performance up to 5 C.

Hierarchy concepts are proposed and applied to illustrate hierarchitectures composed of 2D nanomaterials for energy storage devices. For each class of hierarchical structure, the synthetic mechanisms, methods, and morphology characterizations are presented. For the application in various battery systems, their design rules and unique merits are discussed. Future research towards developing advanced lithium batteries, perspectives and challenges is outlined.

Electrochemical (de)lithiation mechanisms of Cu3P and Sn4P3 Li-ion anodes are investigated by scanning electron microscopy, in situ X-ray diffraction and in situ small angle neutron scattering. It is shown that, for Sn4P3, having an additional alloying reaction induces more surface cracks onto the particles than for Cu3P, resulting in worse stability of the solid electrolyte interphase and shorter cycle life.

The reaction mechanism of nonaqueous SABs: The morphology and composition of discharge products are closely related to electrolytes, catalysts, and gas atmosphere (O2, CO2, H2O) for sodium–air batteries (SABs). The sodium electrochemical reaction mechanisms with air in nonaqueous SABs involve the reversible formation/decomposition reactions of cubic NaO2, nanosheet or nanofilm Na2O2, Na2CO3, NaHCO3, and Na2C2O4 and NaOH.
