Abstract:

Hybrid batteries can fulfill the current global energy quest as they have obtained high energy density (battery) and high-power characteristics (supercapacitor). Here, we have demonstrated the effect of Lithium with copper MOF for batteries applications. Initially, the electrochemical characterizations of manganese sulfide were analyzed in three electrode assembly. Electrochemical measurements in particular cyclic voltammetry, galvanostatic charge discharge and impedance spectroscopy were studied to scrutinize the nature of the electrodes. The LiCu MOF shows battery grade nature with superior specific capacity of 608.08 C/g at 2.2 A/g. On account of high electrochemical performance, the prominent electrode was employed with activated carbon to explore hybrid battery applications. The hybrid device (S2// AC) has revealed exceptional specific capacity of 265 C/g at 2 A/g and 519.8 C g-1 at 3 mV s-1. Also, the S2//AC device manifests remarkable specific power and energy of 1700 W/ kg and 62.5 Wh/kg, respectively. Furthermore, a simulation approach was used to evaluate the contribution of capacitive and diffusive by applying Dunn’s model. The nature of the asymmetric device was also confirmed by calculating its b fitting values. This study shows that the LiCu MOF has the potential to be utilized for efficient energy storage systems.
