Exploring a safer replacement of Li metal anode is crucial for technological, and fundamental importance. Li-metal is a preferred choice as anode material for lithium-ion battery (LIB) applications. However, parasitic dendritic growth on the Li metal surface during cycling causes instability and safety dreads. In the present study, we have investigated that the pre-lithiated ZnMoO4 is superior to its carbon-based counterparts (r-GO@ZnMoO4), moreover safer and sustainable than Li metal anode. The pre-lithiated ZnMoO4 delivers a better reversible capacity (∼1000 mAhg−1 at 0.1 Ag−1), superior rate capability (∼400 mAh g1 at 2 Ag−1), and excellent cycling stability over 300 cycles at 0.1 Ag−1, as compared to bare ZnMoO4 and r-GO@ZnMoO4 composite. The present investigation is an attempt to provide a substitute for commonly used Li-metal/carbon anodes with better performance.

预锂化ZnMoO4和r-GO @ ZnMoO4复合阳极在锂离子电池中的电化学性能

探索安全替代锂金属阳极对于技术和根本重要性至关重要。锂金属是锂离子电池(LIB)应用的阳极材料的首选。然而,在循环过程中锂金属表面上的寄生树枝状生长会导致不稳定和安全恐惧。在本研究中,我们研究了预锂化的ZnMoO 4优于其碳基对应物(r-GO @ ZnMoO 4),而且比锂金属阳极更安全和可持续。预锂化ZnMoO 4提供了一个更好的可逆容量(〜1000 mAhg -1 0.1银-1),优异的倍率性能(〜400毫安- 1在2的Ag -1),并且与裸露的ZnMoO 4和r-GO @ ZnMoO 4复合材料相比,在0.1 Ag -1下在300个循环中具有出色的循环稳定性。本研究试图为具有更好性能的常用锂金属/碳阳极提供替代。
