考虑到需要设计更好的电池以满足大规模储能应用快速增长的需求，电池材料的一个重要方面是元素丰度。为了实现能源的可持续发展，我们必须重新考虑可持续锂供应的可行性，这对锂（离子）电池至关重要。锂在地球上分布广泛，但并不被认为是一种丰富的元素。因此，大规模锂电池的广泛使用将不可避免地受到限制。因此，钠（离子）电池有望大规模应用，因为考虑到其原子量、标准电势和自然丰度，钠是仅次于锂的最有利的电池。可充电钠离子电池由两种不同的钠插入材料组成，类似于锂离子电池。自20世纪80年代初以来，钠插入材料，特别是层状氧化物，已经得到了研究，但由于20世纪90年代对锂插入材料的兴趣扩大，对储能装置的研究并不广泛。近年来，材料研究人员再次广泛探索新的钠插入材料，以提高电池的性能。本文综述了层状过渡金属氧化物钠作为钠离子电池正极材料的最新进展和发展趋势。
Considering the need for designing better batteries to meet the rapidly growing demand for large-scale energy storage applications, an aspect of primary importance for battery materials is elemental abundance. To achieve sustainable energy development, we must reconsider the feasibility of a sustainable lithium supply, which is essential for lithium(-ion) batteries. Lithium is widely distributed in the Earth, but is not regarded as an abundant element. Therefore, widespread use of large-scale lithium batteries would be inevitably restricted. Sodium (-ion) batteries are thus promising candidates for large-scale applications because sodium is the most advantageous next to lithium considering its atomic weight, standard potential, and natural abundance. Rechargeable sodium-ion batteries consist of two different sodium insertion materials similar to Li-ion batteries. Sodium insertion materials, especially layered oxides, have been studied since the early 1980s, but not extensively for energy storage devices due to the expanded interest in lithium insertion materials in the 1990s. In recent years, materials researchers have again been extensively exploring new sodium insertion materials to enhance battery performance. This article reviews recent advancements and trends in layered sodium transition metal oxides as positive electrode materials for Na-ion batteries.
