From environmental waste to energy storage, waste boxes converted into conductive electrodes to further grow active materials has been an interesting way of upcycling. In this study, we transformed waste boxes of KIMTECH Kimwipes® into conductive f-MWCNTs light and flexible substrate (LFS) as current collectors. Then, undoped and P-doped active materials consisting of layered quadruple hydroxides (LQH) was successfully grown on the conductive f-MWCNTs/LFS. Specifically, P-doped f-MWCNTs/LQH demonstrates 1.8 times the capacitance of an undoped f-MWCNTs/LQH. Such conversion of waste boxes not only offers a useful way of reusing waste papers which commonly ends in landfills, but the inexpensive method also offers an extreme way of cutting cost in developing conductive substrates. Also, the effective strategy of synthesizing active materials on the conductive f-MWCNTs/LFS paves its way as potential cheap electrodes of the future generation.
从环境废物到能源存储，将废物盒转化为导电电极以进一步生长活性材料一直是一种有趣的升级再造方式。在这项研究中，我们将 KIMTECH Kimwipes®的废物盒转化为导电 f-MWCNTs 轻质和柔性基底 (LFS) 作为集流器。然后，成功地在导电 f-MWCNTs/LFS 上生长了由层状四氢氧化物 (LQH) 组成的未掺杂和 P 掺杂活性材料。具体来说，P 掺杂的 f-MWCNTs/LQH 的电容是未掺杂的 f-MWCNTs/LQH 的 1.8 倍。这种废物盒的转换不仅为通常最终被填埋的废纸提供了一种有用的再利用方式，而且这种廉价的方法还为开发导电基底提供了一种极端的降低成本的方法。此外，在导电 f-MWCNTs/LFS 上合成活性材料的有效策略为未来廉价电极铺平了道路。
