Calculation on energy densities of lithium ion batteries and metallic lithium ion batteries

Lithium batteries have the highest theoretical energy densities among all electrochemical energy storage devices. Prediction of the energy density of the different lithium ion batteries (LIB) and metallic lithium ion batteries (MLIB) is valuable for understanding the limitation of the batteries and determine the directions of R&D. In this research paper, the energy densities of LIB and MLIB have been calculated. Ourcalculation includes the active electrode materials and inactive materials inside the cell.For practical applications, energy density is essential but not the only factor to be considered, other requirements on the performances have to be satisfied ina balanced way.
