对于经济和可持续能源存储设备的需求促进了当今电池的研究.锂离子电池是目前最成熟的技术,但是电化学储能的应用可通过降低成本和提高安全性进一步扩大.钠和镁离子电池有可能成为两种可行的替代技术.这两种金属比锂更便宜、储量更丰富,并具有更好的安全特性,而且二价镁还有一个附加优势,即每个原子可以传输二倍的电荷.另一方面,钠和镁离子电池都还是新兴的研究领域,仍有很多挑战需要克服.例如,因较大的离子穿梭而造成的重复形变使结合Na+的电极容易粉末化,而镁离子的插入和传输由于较大的静电作用力普遍显示出较慢的动力学特性.本文综述了钠离子电池阴极和阳极材料的概况,并对镁离子电池阴极的研究进行了全面总结.此外,本综述还讨论了文献中常见的一些实验差异,指出了镁离子电化学研究的其他限制,最后,对未来研究提出了有价值的观点和策略.
The demand for economical and sustainable energy storage devices has promoted the research of today’s batteries Lithium-ion batteries are by far the most mature technologies but the use of electrochemical energy storage can be further expanded by reducing costs and increasing safety Sodium and magnesium ion batteries It is possible to become two viable alternatives to these two metals cheaper than lithium, richer reserves, and have better security features, and there is an additional advantage of divalent magnesium, that each atom can transfer twice as much On the other hand, both sodium and magnesium ion batteries are still new research areas and many challenges still need to be overcome.For example, the repeated deformation due to the larger ion shuttle makes the Na + -added electrode easy to powder, whereas the magnesium ion Due to the larger electrostatic force generally showed a slower kinetic properties.In this paper, an overview of the cathode and anode materials for sodium ion batteries is summarized, and the research on the cathode of magnesium ion batteries is summarized.In addition, The review also discusses some of the experimental differences common in the literature, pointing out other limitations of magnesium ion electrochemistry and, finally, valuable future research Ideas and strategies.
