2) The figure shows the construction of a lithium ion battery as well as the movement of electrons and ions under charging conditions. This problem involves discharging. Lithium ion batteries typically have a voltage of 4 volts. The metal oxide is LiCoO2. It has a density of 4.9 gm/cms. The graphite is a layered material where each layer consists of carbon hexagons, C6. It has density of 2.266 gm/cm3. Lithium can intercalate between the layers to form a material that has the approximate LiC6, e. one Lit for every 6 carbons. Both electrodes have dimensions of 10x10 cm2. When the battery is used as a galvanic cell, electrons and L flow from the graphite to the LiCoO2 electrode. If the battery were to be completely charged, all of the Li would be in the graphite and the cathode would be Co02. The current that can be drawn is limited by diffusion of Lit ions from the graphite to the CoO2. The distance required for diffusion is

Explanation / Answer

In order to get current from density the formula is given as below J=I/A J=4.9/0.05=98ampers
