Because of the huge demand for energy materials, it is paramount to develop practical, low-cost, and renewable energy systems. Until now, batteries made of green materials have either been costly or of limited use. Herein, this paper reports the pioneer utilization of fish waste, doped with Pd nanoparticles (Pd NPs) by incipient wetness impregnation to form Pd/Fish-Collagen. The Pd/Fish-Collagen was first used as a catalyst to abate benzene, and then utilized as anode material in three different rechargeable battery systems; Li-, Na-, and Mg- ion batteries. XRD patterns confirmed that the Fish-Collagen (CaS and CaCO₃) was amorphous, while the Pd/Fish-Collagen sample exhibited broad peaks assigned to a mixture of Pd and PdO NPs coexisting with the amorphous Fish-Collagen. TEM and HRTEM images confirmed that the Fish-Collagen and the Pd NPs had average particle sizes of about 70 and 5 nm respectively. The electrochemical properties of the Pd/Fish-Collagen as an anode material in Li, Na, and Mg-based cells showed reversible capacities of 270, 120, and 105 mA h g⁻¹, respectively. The CV and ex-situ XRD tests suggested a pseudocapacitance reaction occurred in Li and Na storage, while the Mg-based cells presented a conversion reaction. This new strategy to generate electrodes from renewable sources is cost-effective and with optimization, millions of tons of this remaining waste can find potential applications in such energy storage systems.

由于对能源材料的巨大需求，开发实用，低成本和可再生能源系统至关重要。到目前为止，由绿色材料制成的电池要么昂贵要么使用有限。本文中，本文报道了通过初期湿润浸渍掺入Pd纳米颗粒（Pd NPs）形成Pd / Fish-Cragen的鱼类废物的先驱利用。Pd / Fish-Collagen首先用作减少苯的催化剂，然后在三种不同的可充电电池系统中用作阳极材料。锂离子，钠离子和镁离子电池。XRD图谱证实了鱼胶原蛋白（CaS和CaCO ₃）是无定形的，而Pd / Fish-Cragen样品显示出宽峰，该峰分配给与无定形Fish-Cragen共存的Pd和PdO NP混合物。TEM和HRTEM图像证实了鱼类胶原蛋白和Pd NP的平均粒径分别约为70和5 nm。Pd / Fish-Collagen作为Li，Na和Mg基电池中的阳极材料的电化学性质显示出270、120和105 mA hg ^-1的可逆容量， 分别。CV和异位XRD测试表明在Li和Na储存中发生了假电容反应，而基于Mg的电池则发生了转化反应。这种由可再生资源产生电极的新策略具有成本效益，并且通过优化，数百万吨的剩余废物可以在这种储能系统中找到潜在的应用。
