The development of sustainable and low cost electrode materials for sodium-ion batteries has attracted considerable attention. In this work, a carbon composite material decorated with in situ generated ZnS nanoparticles has been prepared via a simple pyrolysis of the rubber powder from dumped tires. Upon being used as an anode material for sodium-ion batteries, the carbon composite shows a high reversible capacity and rate capability. A capacity as high as 267 mA h g⁻¹ is still retained after 100 cycles at a current density of 50 mA g⁻¹. The well dispersed ZnS nanoparticles in carbon significantly enhance the electrochemical performance. The carbon composites derived from the rubber powder are proposed as promising electrode materials for low-cost, large-scale energy storage devices. This work provides a new and effective method for the reuse of dumped tires, contributing to the recycling of valuable waste resources.

源自废轮胎的橡胶基碳电极材料，可有效存储钠离子†

用于钠离子电池的可持续且低成本的电极材料的开发引起了相当大的关注。在这项工作中，通过对倾倒轮胎中的橡胶粉进行简单的热解，制备了用原位生成的ZnS纳米粒子装饰的碳复合材料。当用作钠离子电池的负极材料时，碳复合材料显示出高的可逆容量和倍率能力。100次循环后，在50 mA g ^-1的电流密度下仍可保持高达267 mA hg ^-1的容量。碳中分散良好的ZnS纳米颗粒显着增强了电化学性能。提出了由橡胶粉衍生的碳复合材料作为低成本，大规模储能设备的有希望的电极材料。这项工作为废弃轮胎的再利用提供了一种新的有效方法，有助于回收宝贵的废物资源。
