On the challenge of developing advanced technologies for electrochemical energy storage and conversion

TLDR

The rapid growth of miniaturized electronics, electric‑vehicle propulsion, and large‑scale sustainable energy storage drives the development of advanced rechargeable batteries and super‑capacitors, with lithium‑ion batteries offering high energy density but limited cycle life, while super‑capacitors provide high power density and long cycling. This review evaluates lithium‑ion battery technology for electric vehicle applications. The authors survey lithium‑ion batteries and assess alternative systems such as magnesium, Li–sulfur, and Li–oxygen that may serve load‑levelling needs. Recent advances in advanced super‑capacitor research are highlighted.

Abstract

The accelerated production of sophisticated miniaturized mobile electronic devices, challenges such as the electrochemical propulsion of electric vehicles (EVs), and the need for large-scale storage of sustainable energy (i.e. load-levelling applications) motivate and stimulate the development of novel rechargeable batteries and super-capacitors. While batteries deliver high energy density but limited cycle life and power density, super-capacitors provide high power density and very prolonged cycling. Lithium-ion batteries are the focus of intensive R&D efforts because they promise very high energy density that may be suitable for electrical propulsion. Here, we review research on batteries with an emphasis on Li-ion battery technology, examining its suitability for EV applications. We also briefly examine other battery systems that may be of importance for load-levelling applications, including rechargeable magnesium batteries. We give a short review of the status of technologies beyond Li-ion batteries, including Li–sulfur and Li–oxygen systems. Finally, we briefly discuss recent progress in the R&D of advanced super-capacitors.
