能源生产和储存已成为关系到我们日常生活福祉的关键问题。目前电池面临的挑战是双重的。首先，对便携式电子设备和零排放车辆的供电系统的日益增长的需求刺激了对高能量和高电压系统的研究。其次，需要低成本电池才能向智能电网迈进，智能电网整合可再生能源的不连续能量流，优化清洁能源的性能。钠离子电池可能是第二点的关键，因为钠的大量可用性，其低廉的价格以及Li和Na插入化学的相似性。尽管基于Na离子的技术的能量密度和电压较低，但它们可以专注于重量和占地面积要求不太剧烈的应用，例如电网存储。为了赶上锂离子技术，在钠离子领域还需要做很多工作。必须优化阴极和阳极材料，新的电解质将是钠离子成功的关键。本综述将收集有关钠离子电池材料的最新知识，旨在为已经探索的系统提供广泛的视角，并为该电池技术的新研究提供起点。
Energy production and storage have become key issues concerning our welfare in daily life. Present challenges for batteries are twofold. In the first place, the increasing demand for powering systems of portable electronic devices and zero-emission vehicles stimulates research towards high energy and high voltage systems. In the second place, low cost batteries are required in order to advance towards smart electric grids that integrate discontinuous energy flow from renewable sources, optimizing the performance of clean energy sources. Na-ion batteries can be the key for the second point, because of the huge availability of sodium, its low price and the similarity of both Li and Na insertion chemistries. In spite of the lower energy density and voltage of Na-ion based technologies, they can be focused on applications where the weight and footprint requirement is less drastic, such as electrical grid storage. Much work has to be done in the field of Na-ion in order to catch up with Li-ion technology. Cathodic and anodic materials must be optimized, and new electrolytes will be the key point for Na-ion success. This review will gather the up-to-date knowledge about Na-ion battery materials, with the aim of providing a wide view of the systems that have already been explored and a starting point for the new research on this battery technology.
