Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Based on this model, the effects of the electrode design parameters (electrode thickness, volume fraction of active material and particle size) on the battery performance (electrochemical characteristics, thermal behavior, energy density and power density) were initially investigated.
In this plot the dots represent data from real cell datasheets. The main chemistries are: In a rechargeable lithium ion battery lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. Current production cells have an energy density ~280Wh/kg.
The anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
According to Sun et al.’s estimation on a Li | Li 6 PS 5 Cl | LiNi 0.8 Mn 0.1 Co 0.1 O 2 battery 12, the decrease of solid electrolyte content from 30 to 10 wt% in the composite positive electrode would increase the specific energy from 320 Wh kg –1 to about 426 Wh kg –1.
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
