Lithium (Li) metal is an attractive anode for next-generation high-energy-d. rechargeable batteries due to its high theor. capacity and low redox potential. However, the uncontrolled growth of Li dendrites and infinite volume change during Li stripping/plating process lead to low coulombic efficiency and safety concern. To solve these critical issues, copper foam with Cu2O nanowire arrays (COCF) is rationally designed and used as three-dimensional (3D) conductive skeleton for compositing Li. Cu2O nanowire arrays structure with strong capillary forces and lithiophilicity is beneficial for the wetting of molten Li on surface and Li + nucleation. In addition, the 3D robust Cu skeleton with porous structure can reduce the local c.d. and regulate the distribution of Li+ flux on the electrode surface, leading to homogeneous nucleation and deposition of lithium, as well as mitigating the volume expansion. As a result, the COCF-Li composite lithium anode exhibits a prolonged cycling stability over 1000 h with a low over-potential of ∼50 mV at a c.d. of 1 mA•cm-2 in a sym. cell. Even at a c.d. of 4 mA•cm-2 and deposition capacity of 4 mAh•cm-2, it still delivers a stable cycling performance for 600 h. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2HPLC of Formula: 20427-59-2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to the earth-abundant, inexpensive and low toxicity. The copper-mediated C-C, C-O, C-N, and C-S bond formation is a part of one oldest reaction, emphasizing the Ullmann cross-coupling reaction.HPLC of Formula: 20427-59-2
