最新Chem Soc Rev封面综述文章:超快充放电锂离子电池的电极材料设计?Rational Material Design for Ultrafast Rechargeable Lithium-ion Batteries Rechargeable lithium-ion batteries (LIBs) are important electrochemical energy storage devices for consumer electronics and emerging electrical/hybrid vehicles. However, one of the formidable challenges is to develop ultrafast charging LIBs with the rate capability at least one order of magnitude (>10 C) higher than that of the currently commercialized LIBs. This tutorial review presents the state-of-the-art developments in ultrafast charging LIBs by the rational design of materials. First of all, fundamental electrochemistry and related ionic/electronic conduction theories identify that the rate capability of LIBs is kinetically limited by the sluggish solid-state diffusion process in electrode materials. Then, several aspects of the intrinsic materials, materials engineering and processing, and electrode materials architecture design towards maximizing both ionic and electronic conductivity in the electrode with a short diffusion length are deliberated. Finally, the future trends and perspectives for the ultrafast rechargeable LIBs are discussed. Continuous rapid progress in this area is essential and urgent to endow LIBs with ultrafast charging capability to meet huge demands in the near future. 可充电 锂离子电池 是消费电子产品和新兴电/混合动力汽车重要的电化学能量存储设备。然而,其挑战之一是,开发超快充电电池的充电速率具有比当前商品化电池的高至少一个数量级。这个综述文章提出了目前的最先进的发展超快电池的材料合理设计方案。首先,论文先总结了基本的电化学和相关的离子/电子传导理论,确定LIBS的速率能力是由电极材料的固态扩散过程所限制。然后,讨论了本征材料,材料修饰和加工,以及扩散长度的电极最大化两者的离子和电子导电性的电极材料结构设计等几个方面。最后,未来的发展趋势和前景的超快充电电池进行了讨论。当前,在超快充电电池的研究方面是必要和迫切的,以满足在不久的将来巨大能量储存的需求。 觉得不错麻烦给个金币! 2015-CSR-Rational Material Desargeable Lithium-ion Batteries 1.jpg查看更多1个回答 . 11人已关注
