Example text

This layer is beneficial and essential for proper cell operation, but an electrolyte reduction side reaction can occur that causes aging. , ethylene carbonate) reacts to increase the thickness of the SEI layer due to product precipitation. A surface film on the active particles also occurs in the cathode. The film thickness does not change significantly during aging, but its porosity, conductivity, and diffusion coefficient do change over time due to precipitate of side-reaction product that blocks the pores of the existing surface film.

7) + The HSO− 4 and H ions come from dissolved H2 SO4 . The acid is consumed in both the positive and negative electrodes during discharge. The H+ ions produced in the negative Governing Equations 25 electrode migrate to the positive electrode. 8) of H2 SO4 is consumed at each electrode. This example shows the need to balance the various species in a cell to maximize energy storage. Acid, Pb, and PbO2 are all consumed during discharge but at different rates. For maximum energy storage, all three active materials should be expended at the same time.

The ions originate in one insertion electrode, travel through the electrolyte, and intercalate in the other insertion electrode. Electrons enter or leave the crystal to maintain electroneutrality and produce the desired current flow. 1 Ion Transport Transport in the electrolyte phase of batteries involves the movement of charged species (ions) across the cell and the corresponding changes in ionic concentration distribution c(x, t) that depend on the position in the cell x and time t. Ni–MH and Li-ion batteries have one kind of charged species that travels through the unary electrolyte.
