The ever-growing demand for advanced rechargeable lithium-ion batteries in portable electronics and electric vehicles has spurred intensive research efforts over the past decade. The key to sustaining the progress in Li-ion batteries lies in the quest for safe, low-cost positive electrode (cathode) materials with desirable energy and power capabilities. One approach to boost the energy and power densities of batteries is to increase the output voltage while maintaining a high capacity, fast charge–discharge rate, and long service life. This review gives an account of the various emerging high-voltage positive electrode materials that have the potential to satisfy these requirements either in the short or long term, including nickel-rich layered oxides, lithium-rich layered oxides, high-voltage spinel oxides, and high-voltage polyanionic compounds. The key barriers and the corresponding strategies for the practical viability of these cathode materials are discussed along with the optimization of electrolytes and other cell components, with a particular emphasis on recent advances in the literature. A concise perspective with respect to plausible strategies for future developments in the field is also provided.

锂离子电池高压正极材料

在过去的十年中,便携式电子产品和电动汽车对高级可充电锂离子电池的需求不断增长,这促使人们进行了大量的研究工作。维持锂离子电池进步的关键在于寻求安全,低成本,具有所需能量和功率能力的正极(阴极)材料。提高电池能量和功率密度的一种方法是增加输出电压,同时保持高容量,快速的充放电速率和较长的使用寿命。这篇评论介绍了各种新兴的高压正电极材料,它们有可能短期或长期满足这些要求,包括富镍层状氧化物,富锂层状氧化物,高压尖晶石氧化物,和高压聚阴离子化合物。讨论了这些阴极材料实用可行性的主要障碍和相应策略,以及电解质和其他电池组件的优化,特别强调了文献中的最新进展。还提供了关于该领域未来发展的合理战略的简要观点。
