The introduction of battery-type materials into the positive electrode enhances the energy density of the system, but it comes with a tradeoff in the power density and cycle life of the device. Most of the energy in this system is provided by the battery materials, making it, strictly speaking, a battery-type capacitor. 4. Summary
On the other hand, the capacitor-type electrode is used to improve the power densities of the cells compared to the typical batteries. The main reason is that the capacitor component can improve the electron transfer to the battery component in the hybrid system, causing a better charge transfer reaction at high rates.
Unlike the capacitor material, the battery material is not able to withstand a high rate and long-term current impact, which ultimately affects the power performance and cycle performance of the device. Figure 17. LIBCs with different battery material contents in the cathode: (a) Ragone plot; (b) Cycle performance .
However, because of the low rate of Faradaic process to transfer lithium ions (Li+), the LIB has the defects of poor power performance and cycle performance, which can be improved by adding capacitor material to the cathode, and the resulting hybrid device is also known as a lithium-ion battery capacitor (LIBC).
The battery-capacitor composite positive electrode and pre-lithiated battery-type negative electrode [180, 181]. The introduction of battery-type materials into the positive electrode enhances the energy density of the system, but it comes with a tradeoff in the power density and cycle life of the device.
This takes the pressure off the battery, preventing large current surges and deep discharges. However, the battery remains the primary source of power for continuous operation. Once the transient passes, the battery can replenish the supercapacitor's charge and continue powering the system.
