The formation of the alkyl carbonate-derived solid electrolyte interphase (SEI) enables the use of active materials operating at very cathodic potentials in Li-ion batteries. However, the SEI in semi-solid flow batteries results in a hindered electron transfer between a fluid electrode and the current collector restricting the operating potentials to ca. 0.8 V vs. Li/Li(+) for EC-based electrol...

Lithium-ion batteries are the state-of-the-art power source for most consumer electronic devices. Current collectors indispensable components bridging lithium-ion and external circuits, greatly influencing capacity, rate capability long-term stability of batteries. Conventional current collectors, Al Cu foils have been used since first commercial battery, over past two decades, thickness these ...

While the Mo6S8 chevrel phase is frequently used as cathode material in Mg-ion batteries, theoretical studies on this are comparatively scarce. The particular structure of phase, with rather loosely connected cluster entities, points to important role dispersion forces material. However, so far aspect has been completely neglected discussion for mono- and multivalent-ion batteries. In work we t...

Incorporation of reduced graphene oxide into β-Ni(OH)(2) presents high performances with specific discharge capacity of 283 mA hg(-1) after 50 cycles in Ni-MH batteries, and 507 mA hg(-1) after 30 cycles in Li ion batteries.

Sodium-ion batteries have recently attracted significant attention as an alternative to lithium-ion batteries because sodium sources do not present the geopolitical issues that lithium sources might. Although recent reports on cathode materials for sodium-ion batteries have demonstrated performances comparable to their lithium-ion counterparts, the major scientific challenge for a competitive s...

Heterogeneous nanostructures may offer better or new properties that are not originally present in constituting components by judiciously combining two or more different materials. For example, silicon coating on carbon nanotubes (CNTs) improves the thermal stability of carbon nanotubes by acting as a protective fi lm, [ 1 ] and silicon-coated CNT composites have been proposed as promising lith...
