过渡到电气化运输需要在可持续性，能量密度，功率密度，寿命和批准锂离子电池的成本方面进行改进，在下一代阴极的开发中仍然存在重大机会。这提出了一个高度复杂的多参数优化挑战，其中阴极化学设计和发现，理论和实验理解，结构和形态控制，合成方法和成本降低策略的发展可以提供近期和长期所需的性能增强。这一多方面的挑战需要跨学科的方法来解决，世界各地已经建立了许多学术和工业联盟，专注于阴极开发。其中一个例子是下一代锂离子阴极材料项目FutureCat，该项目由英国法拉第研究所于2019年建立，用于电化学储能研究，旨在发展我们对现有和新发现的阴极化学的理解。在这里，我们提出了我们对持续存在的基本挑战的看法，包括保护涂层和添加剂，以延长寿命和改善界面离子传输，现有阴极材料的设计和新阴极材料的发现，其中阳离子和阳离子加阴离子氧化还原活性可以被利用来增加能量密度，地球丰富元素的应用，最终可以降低成本，以及能够延长电池寿命的抗断裂的新电极拓扑结构的交付。nbsp;（C）2021年作者。
Transitioning to electrified transport requires improvements in sustainability, energy density, power density, lifetime, and approved the cost of lithium-ion batteries, with significant opportunities remaining in the development of next-generation cathodes. This presents a highly complex, multiparameter optimization challenge, where developments in cathode chemical design and discovery, theoretical and experimental understanding, structural and morphological control, synthetic approaches, and cost reduction strategies can deliver performance enhancements required in the near- and longer-term. This multifaceted challenge requires an interdisciplinary approach to solve, which has seen the establishment of numerous academic and industrial consortia around the world to focus on cathode development. One such example is the Next Generation Lithium-ion Cathode Materials project, FutureCat, established by the UK's Faraday Institution for electrochemical energy storage research in 2019, aimed at developing our understanding of existing and newly discovered cathode chemistries. Here, we present our perspective on persistent fundamental challenges, including protective coatings and additives to extend lifetime and improve interfacial ion transport, the design of existing and the discovery of new cathode materials where cation and cation-plus-anion redox-activity can be exploited to increase energy density, the application of earth-abundant elements that could ultimately reduce costs, and the delivery of new electrode topologies resistant to fracture which can extend battery lifetime.& nbsp;(C) 2021 Author(s).
