碳纤维（CF）通常是优选的，因为它被认为是多功能轻质复合材料，其中CF不仅充当具有高性能结构增强的设备的一个完全集成的部分，而且还充当电池电极之一以存储能量。然而，商用碳纤维在结构化锂离子电池中的电化学容量限制是一个亟待解决的问题。因此，在这项工作中，开发了一种新的策略，采用一步四氯化锡溶剂热法制备CF@SnO2复合材料。通过在碳纤维上牢固地生长二氧化锡，形成协同电极，可以改善碳纤维的性能。当作为阳极材料进行测试时，在100 mAh g − 1的电流密度下保持510 mAh g − 1的高可逆容量，直到150次循环都没有明显的衰减（比纯CF的容量大幅增加高达637.5%）。此外，我们的策略揭示了一个可实现的路线，这可能是一个有前途的方式，使可持续的阳极SLIB和碳基多功能复合材料的其他实际应用。
The carbon fiber (CF) is frequently preferred because it is considered as a multifunctional lightweight composite, where the CF is not only acted as one completely integrated part of the device with high-performance structural reinforcement, but also served as one of the battery electrode to storage energy. However, the limitation of electrochemical capacity of commercial CFs for the structural lithium-ion battery (SLIB) is an urgent issue should be solved. Therefore, in this work, a novel strategy to fabricate CF@SnO2 composite is developed by employing one-step tin tetrachloride solvothermal method. The performance of the CFs could be improved by growing the stannic oxide firmly on each CF to form a synergetic electrode. When tested as anode materials, a high reversible capacity of 510 mAh g−1 at a current density of 100 mAh g−1 is maintained without obvious decay up to 150 cycles (a huge increase as high as 637.5% than that of the pure CFs). Furthermore, our strategy reveals an attainable route, which could be as a promising way to make a sustainable anode for SLIBs and carbon-based multi-functional composite for other practical applications.
