[3, 4] The recent rise of the demand for high rate, high capacity, quick-charging LIBs to meet the portable devices with prolonging stand-by time, electric vehicles with long-distance driving range (>500 km), and batteries with short charging time (<20 min), has stimulated research efforts in battery systems with high-energy-density and high-power-density.
Simultaneous realization of high safety and high energy density/performance is a perpetual pursuit. Unfortunately, conventional batteries are passive devices where the performance, safety, and calendar/cycle life are all dictated by the electrochemical reactivity at ever-present anode/electrolyte and cathode/electrolyte interfaces.
The design strategies of the gradient cathodes, lithium-metal anodes, and solid-state electrolytes are summarized. Future directions and perspectives of gradient design are provided at the end to enable practically accessible high-energy and high-power-density batteries. The authors declare no conflict of interest.
An inherent conflict between the reactivity and stability of battery materials persists at the electrode/electrolyte interfaces (EEIs). More specifically, highly reactive electrode/electrolyte materials provide high power and high performance but result in poor safety and accelerated degradation even when the battery is not in use.
Rechargeable lithium-ion batteries (LIBs) are widely used in electrified vehicles, consumer electronics, and stationary energy storage systems. Simultaneous realization of high safety and high energy density/performance is a perpetual pursuit.
