Themed collection Electric vehicles and batteries

In this perspective, we make a systematic summary and give out our comments on constructing nitrided interfaces for stabilizing Li metal electrodes.

An overview of the strategies developed in our research to create graphene-based electrodes with better ionic conductivity, electron mobility, specific surface area, mechanical properties, and device performance than state-of-the-art electrodes.

Our work aims to identify critical factors that could become equally important in a coincident sustainability assessment of new green energy vehicle technologies with utilization of food waste as an alternative renewable resource to fossil fuels.

A 2.5 to 3.4 V Zn|MnO₂ membrane-less solid-state battery accessing the 617 mA h g⁻¹ theoretical capacity of MnO₂ and its application in e-mobility is reported. This concept is made possible by a buffering layer that regulates the battery’s pH.

We demonstrate that contrary to previous reports, transference number decreases with increasing degree of polymerization in non-aqueous lithium-bearing polyelectrolyte solutions that have been proposed as next-generation battery electrolytes.

Driving style is one of the typical factors that impact vehicle energy management during real-world vehicular operation.

Constant current charging and discharging is widely used nowadays for commercial lithium (Li) ion batteries (LIBs) in applications of portable electronic devices and electric vehicles.

Vehicle-to-grid (V2G) allows electric vehicles to provide power and services to the grid. At scale, V2G can bolster renewable energy growth and eliminate storage and displace firm generators traditionally used to balance wind and solar intermittency.

A bifunctional electrolyte was developed for aqueous zinc-ion batteries, which embeds impact resistance in the aqueous electrolyte and maintains a high-performance for full batteries.

The ISC criteria at the component level which can provide guidance for battery safety design.

Fast charging of lithium-ion cells is key to alleviate range anxiety and improve the commercial viability of electric vehicles, which is, however, limited by the propensity of lithium plating.

External vibrations can destroy the specific capacitance in supercapacitors. Carbon based supercapacitors show a higher ability to absorb the impacts of external vibrations, in comparison to metal oxide based pseudocapacitors.

This work shows the feasibility of a self-supporting V₂O₅ nanofiber-based cathode for magnesium–lithium-ion batteries reaching an energy density of 280 W h kg⁻¹.
