储能技术是可再生能源顺利并网的核心技术。其中，钠离子电池因其丰富的资源和广泛的分布，具有潜在的低成本，显示出很大的发展前景。然而，对于钠离子电池的商业化来说，负极仍然是一个巨大的挑战。本文报道了一种通过一种简单的碳化工艺制备的低成本、高安全性的热解无烟煤负极材料。实验表明，PA负极材料具有良好的钠存储性能，实际能量密度为100Wh kg(-1)，具有良好的倍率和循环性能。此外，一系列的安全实验也证明了采用PA阳极的袋式电池具有很高的安全性。PA负极的这些理想性能可以满足实际应用的要求，为低成本、高安全性的大规模电能储存用钠离子电池的工业化生产铺平了道路。(C)2016爱思唯尔B.V.保留所有权利。
Energy storage technologies are the core technology for smooth integration of renewable energy into the grid. Among which sodium-ion batteries show great promise due to the potential low cost originated from the abundant resources and wide distribution of sodium. However, the anode still remains great challenge for the commercialization of sodium-ion batteries. Here we report a pyrolyzed anthracite (PA) anode material with superior low cost and high safety through one simple carbonization process. The PA anode material shows promising sodium storage performance demonstrated by prototype pouch cells with a practical energy density of 100 Wh kg(-1), good rate and cycling performance. Furthermore, the high safety of pouch cells with PA anode was also proved by a series of safety experiments. These desirable properties of the PA anode can meet the requirements for practical applications and pave the way for the industrial production of low-cost and high-safety sodium-ion batteries for large-scale electrical energy storage.
