High-nickel layered oxide cathode materials will be at the forefront to enable longer driving-range electric vehicles at more affordable costs with lithium-based batteries. A continued push to higher energy content and less usage of costly raw materials, such as cobalt, while preserving acceptable power, lifetime and safety metrics, calls for a suite of strategic compositional, morphological and microstructural designs and efficient material production processes. In this Perspective, we discuss several important design considerations for high-nickel layered oxide cathodes that will be implemented in the automotive market for the coming decade. We outline various intrinsic restraints of maximizing their energy output and compare current/emerging development roadmaps approaching low-/zero-cobalt chemistry. Materials production is another focus, relevant to driving down costs and addressing the practical challenges of high-nickel layered oxides for demanding vehicle applications. We further assess a series of stabilization techniques on their prospects to fulfill the aggressive targets of vehicle electrification.

高镍层氧化物阴极材料将在最前沿，以锂基电池以更实惠的价格实现更长的续驶里程的电动汽车。在保持可接受的功率，寿命和安全指标的同时，不断提高能源含量并减少使用昂贵原料（如钴）的呼吁，要求采取一系列战略性的成分，形态和微观结构设计以及有效的材料生产工艺。在本《观点》中，我们讨论了高镍层氧化物阴极的几个重要设计考虑因素，这些阴极将在未来十年中在汽车市场中实现。我们概述了最大限度地提高其能量输出的各种内在限制，并比较了接近低/零钴化学的当前/新兴发展路线图。材料生产是另一个重点，与降低成本和解决高镍层氧化物在苛刻的车辆应用中的实际挑战有关。我们进一步评估了其前景的一系列稳定技术，以实现汽车电气化的积极目标。
