摘　　要：碳纤维结构电池具有碳纤维增强复合材料优异的力学性能,同时又具有良好的储能性能,在航空航天、新能源汽车等领域有广阔的应用前景。本文采用湿法涂覆工艺,制备了超薄镀镍碳纤维电池(Nickel-plated Carbon Fiber Battery,Ni-CFB);基于嵌入集成式结构电池的设计方法,以该电池为芯部,碳纤维编织布为蒙皮,采用真空树脂传递工艺制备了碳纤维增强复合材料三明治结构电池管(Sandwich Structure Battery Tube,SSBT),测试了Ni-CFB的电化学性能,评价了SSBT在不同受载条件下电化学性能衰减行为。结果表明:Ni-CFB在0.1 C的充放电倍率下比容量达到156 mAh/g,比磷酸铁锂-石墨体系常规电池的比容量高30%;在压缩载荷比和弯曲载荷比分别达到550 N/g和89.1 N/g的条件下,SSBT的电容量分别保持在80%和60%以上,表明SSBT具有良好的结构效能和储能效能,在储能系统轻量化设计和安全性设计方面具有巨大的潜力。Carbon fiber structure battery has both excellent mechanical properties of carbon fiber reinforced composite materials and good energy storage performance,which has broad application prospects in aerospace,new energy vehicles and other fields.In this article,ultra-thin nickel-plated carbon fiber battery(Ni-CFB)was prepared by coating process.Based on the design method of embedding integrated structure battery,the sandwich structure battery tube(SSBT)was prepared by resin vacuum transfer process,with the battery as the core and the carbon fiber braid as the skin.The electrochemical properties of Ni-CFB were tested,and the electrochemical performance attenuation behaviors of SSBT under different loading were evaluated.The results show that the specific capacity of Ni-CFB reaches 156 mAh/g at a charge-discharge rate of 0.1 C,which is 30%higher than the specific capacity of conventional batteries of lithium-iron phosphate-graphite system.When the compression loading ratio and flexure loading ratio reach 550 N/g and 89.1 N/g,the capacity of SSBT is remained at 80%and 60%or more,respectively.Results indicate that SSBT has good structural efficiency and energy storage efficiency,which has great potential in lightweight design and safety design on energy storage systems.
