低缺陷低孔隙度硬碳用于高库仑效率高容量钠离子电池负极

由于具有良好的成本效益和电化学稳定性，碳基材料作为钠离子电池的负极材料前景诱人。其中硬碳已作为钠离子电池的负极材料进行了深入研究。硬碳可通过各种含碳物质产生，包括生物质(如纤维素、花生壳、香蕉和柚子皮)以及有机聚合物(如酚醛树脂、聚苯胺、聚乙烯)。然而，上述硬碳材料的应用很大程度上受到了低初始库仑效率(ICE)的限制。研究人员已广泛研究了热解温度对硬碳的微观结构以及电化学性能的影响。一般来说，随着热处理温度的增加，石墨化程度随之提升，使得硬碳的表面积和孔隙度降低，同时缺陷的含量也有所降低。硬碳的表面积(孔隙度)和缺陷含量是影响其电化学性能的重要因素，这些电化学性能包括可逆容量、操作电压和初始库仑效率。

近日，美国太平洋西北国家实验室Liu Jun博士、武汉大学曹余良教授等系统地调控具有相似整体架构硬碳的缺陷含量和孔隙度，并在Adv. Energy Mater.上发表了题为“Low-Defect and Low-Porosity Hard Carbon with High Coulombic Efficiency and High Capacity for Practical Sodium Ion Battery Anode”的研究论文。该工作提出石墨层中的缺陷与ICE直接相关，缺陷会捕获钠离子并产生排斥其他钠离子的电场，降低了低压插层容量。所得低缺陷和孔隙度的硬碳电极获得了高达86.1%的ICE(纯硬碳材料导电炭黑为94.5%)，其可逆容量为361mAh·g-1，循环稳定性良好(100次循环后容量保留93.4%)。该工作揭示了可行的高性能储钠硬碳设计原则，即合适的碳层距离以及无缺陷的石墨层。

层状锂锰氧（LRMO）正极材料因具有高的比容量（> 250 mAh/g）和电势电位, 当和硅负极匹配的时候，可以构造出开路电压为5V的全电池，且释放高达500 Wh/kg的理论容量。但目前的碳酸酯电解液通常具有较差的阳极稳定性，在高压下容易被氧化，极大限制了这类材料的商业进展。为提高电解液的电化学窗口，通常具有两种策略：1、高度浓缩电解液； 2、氟化溶剂分子作为电解液添加剂。但其中高度浓缩的电解液由于盐浓度远大于1M，使得在使用中电解液的粘稠度急剧上升，大大降低了电池的倍率性能，进而阻碍了这类电解液的商业化进展。相比之下，由于氟原子高的电子受体（电负性）和低的极化度，使得氟化有机分子具有高氧化稳定性、低熔点和高闪点的优点，因此氟化溶剂分子被目前认为是一种最理想的策略。特别是以磷酸盐为基础的氟化溶剂分子，这类溶剂分子可以借助磷酸盐来捕获可燃性自由基，如氧自由基等，实现电解液的阻燃性。

   武汉大学化学与分子科学学院曹余良教授团队在Wiley出版集团新推出的信息材料领域高影响力期刊InfoMat上发表的题为“Enabling an intrinsically safe and high-energy-density 4.5 V-class Li-ion battery with nonflammable electrolyte”的文章中，报道了一种以磷酸酯为基础的三(2,2,2-三氟乙基)亚磷酸酯（TFEP）来完全替代酯类电解液的一种新型策略，证实了在完全取代酯类溶剂的情况下，仍然能够实现稳定循环的高压锂离子电池，为高压阻燃性电解液的设计提供了一种新方法和策略。
   三(2,2,2-三氟乙基)亚磷酸酯（TFEP）是一种高度氟化的磷酸盐，沸点高达186℃，是目前商业电解液的2-3倍，完全避免了目前电解液易挥发的缺点。同时由于磷酸盐和氟原子的存在，这种电解液可以基本满足目前对电解液的需求，即不可燃烧、热稳定和较高的离子电导率。当采用5 voL%的FEC和5 voL% VC作为添加剂的时候，以硅为负极，锂锰氧为正极的全电池测试中，可实现在200次循环后，容量为72%，平均库伦效率维持在99.7%的高性能锂离子电池。除此之外，这种高度氟化的电解液由于采用较低盐浓度（0.8 M LiPF6）可以有效降低高度浓缩电解液带来的盐成本问题，为后续设计多功能磷化溶剂提供了一种崭新的思路。
