Diagram of lithium-ion battery cell components. Image used courtesy ofUL Research Institutes Thermal instability is one major concern that arises as researchers experiment with battery components. Thermal runawaycan happen when the integrity of the separator between the cathode and anode is compromised,...
Cell AgingAs a Lithium-Ion cell ages it loses its ability to store charge. Figure 3 shows the effects of repeatedly charging and discharging the cell at room temperature. By maintaining an ongoing coulomb count of the charge on the cell it can be shown that aging affects the "Full" point ...
Goodenough’s group began to explore oxide cathodes in the 1980s at the University of Oxford in England. The cell voltage is determined by the energy difference between the redox energies of the anode and the cathode. This means that the cathode energy should lie as low as possible...
