  • How to calculate the conversion rate of n-type batteries

    How to calculate the conversion rate of n-type batteries

    Lithium metal is an ideal anode material for Li batteries due to the following properties. 1. Low density: 0.534 g cm-3 2. Low reduction potential: -3.04 V vs SHE 3. High theoretical specific capacity: 3861 mAh g. In general, there are two representative energy density metrics for batteries: 1) gravimetric energy density (energy stored per unit weight of a battery) and 2) volumetric energ. The N/P ratio describes the capacity ratio between the electrodes in the battery cell. The interpretation of N/P ratio is slightly different based on the lithiated states of cathode material. For the ease of calculating N/P ratio for Li metal batteries, often areal capacities in unit of mAh cm-2for Li metal anode and cathode material are used. It is worth noting that the often the. Fig. 2 illustrates cell structure comparisons between Li-ion cell and Li-metal cell (N/P > 0) with relevant battery components in the cell such as current collectors, separators, and electrodes.
