Strategies toward the development of high-energy-density lithium batteries
The energy density of a lithium battery is also affected by the ionic conductivity of the cathode material. The ionic conductivity (10 −4 –10 −10 S cm −1) of traditional cathode materials is at least 10,000 times smaller than that of conductive agent carbon black (≈10 S cm −1) [[16], [17], [18], [19]].].
