报告摘要: The increasing global consumption of fossil fuels, the consequent undesirable rapid growth of CO2 concentrations and environmental destruction are severe challenges to humankind. The electrification of the transportation sector has gained significant traction in the recent years to deal with these challenges. Two primary forms of vehicle electrification, battery and fuel cell electric vehicles (EVs) have received extensive attention and research. Comparatively speaking, battery seems to have won the first short-term race for green ascendancy, but the case for hydrogen fuel cells refuses to go away, even though its start date is receding into the distance. Some big built-in negatives such as battery production sustainability might undermine battery’s long-term dominance, but renewable energy infrastructure still need more time to be sufficiently developed and able to facilitate a holistic hydrogen economy. In great anticipation, we are witnessing the pendulum swing in favor of battery or fuel cells in long-term race.
Herein, we will first present the technical comparison of batteries and fuel cells, then provide a comprehensive evaluation of emerging electric vehicle markets based on various batteries and hydrogen fuel cells, which have the greatest potential to succeed in commercial applications. Additionally, future prospects about batteries and fuel cells towards long-range, low-cost and high-utilization transportation markets will be proposed, the key points are the next-generation 3D solid-state battery with high safety and better production sustainability, high-efficiency non-precious electrocatalyst with low-cost and long-term stability, and the development of infrastructure for hydrogen transportation and distribution with larger scale and better economic feasibility. Beyond these, we will present our recent progress in advanced batteries and fuel cells by focusing on the aspects of low-cost and high-efficiency electrocatalysts for fuel cells, electrode innovation for batteries, electrolyte design towards high energy density and high safety solid-state batteries.
