对锂离子电池（LIBs）的严重依赖引起了人们对锂和过渡金属的可持续性以及围绕采矿实践的伦理问题的日益关注。开发锂以外的替代能源存储技术已成为全球能源研究组合的重要组成部分。从电气化移动到可再生能源的有效利用，再到大规模的固定储能，替代技术在塑造未来的储能格局方面发挥着至关重要的作用。钾离子电池（PIBs）是一种很有前途的替代方案，因为它具有化学和经济效益，在不同的应用中成为锂离子电池和钠离子电池的有力竞争对手。然而，关于材料中的钾储存过程以及它与锂和钠的区别，以及对pib中固液界面化学的理解严重不足，许多人不知道。因此，在推进PIB技术的商业前景方面还存在一些突出的问题。该路线图强调了最新的科学和技术进步，以及如何解决具有挑战性的问题，以加速pib的发展。我们希望该路线图能够帮助更广泛的PIB研究界，并在快速发展的研究领域为其他锂能源存储技术提供交叉参考。
The heavy reliance of lithium-ion batteries (LIBs) has caused rising concerns on the sustainability of lithium and transition metal and the ethic issue around mining practice. Developing alternative energy storage technologies beyond lithium has become a prominent slice of global energy research portfolio. The alternative technologies play a vital role in shaping the future landscape of energy storage, from electrified mobility to the efficient utilization of renewable energies and further to large-scale stationary energy storage. Potassium-ion batteries (PIBs) are a promising alternative given its chemical and economic benefits, making a strong competitor to LIBs and sodium-ion batteries for different applications. However, many are unknown regarding potassium storage processes in materials and how it differs from lithium and sodium and understanding of solid–liquid interfacial chemistry is massively insufficient in PIBs. Therefore, there remain outstanding issues to advance the commercial prospects of the PIB technology. This Roadmap highlights the up-to-date scientific and technological advances and the insights into solving challenging issues to accelerate the development of PIBs. We hope this Roadmap aids the wider PIB research community and provides a cross-referencing to other beyond lithium energy storage technologies in the fast-pacing research landscape.
