Comparison of capacity, voltage and self-discharge
The energy density of lithium-ion capacitor is lower than that of lithium-ion battery, but its output density is high; The energy density of monomer volume is 10~15Wh/L, which is much larger than the capacity of 2~8Wh/L of double-layer capacitor, and twice that of the latter.
In terms of voltage, the voltage of lithium-ion capacitor can reach 4V, which is similar to that of lithium-ion battery, but much higher than that of double-layer capacitor. At the same time, it is smaller than both in terms of self-discharge.
Security
The cathode of lithium-ion battery uses lithium oxide, which not only contains a large amount of lithium to form lithium dendrites and pierce the diaphragm, but also contains oxygen, an important element of ignition. Once the battery is short-circuited, it can develop into a whole thermal decomposition, and react with the electrolyte to cause combustion. The positive pole of the lithium-ion capacitor is activated carbon. Even if the internal short circuit will react with the negative pole, it will not react with the electrolyte. In theory, it will be much safer than the lithium battery.
Long service life
In order to achieve a long life, lithium-ion batteries have a certain range of limits on their charging and discharging depth, which reduces the capacity that can be used in essence. The charging and discharging principle of double-layer capacitors has a long life simply by adsorbing or removing ions from the electrolyte, which is difficult to extend the actual life. However, even if the positive electrode potential of the lithium-ion capacitor is reduced, the voltage of the unit itself will not drop significantly, so the capacity can be guaranteed.
High temperature resistance
Under high temperature conditions, the electrolyte and positive electrode are prone to oxidative decomposition. Therefore, it may be necessary to reduce the potential of the positive electrode under high temperature conditions, but under the condition of potential reduction, the overall voltage of the double-layer capacitor will drop, and the capacity cannot be guaranteed. However, lithium-ion batteries cannot be depressurized, which is easy to cause safety problems. Only lithium-ion capacitors can be used at the position where the positive potential is far away from the oxidation decomposition area, so the high temperature performance is excellent.
Application and industrialization status of lithium ion capacitors
The upstream of lithium ion capacitor industry mainly includes: positive and negative electrode raw materials, electrolyte, diaphragm, perforated fluid collector and simple metal lithium electrode; The midstream mainly includes lithium-ion capacitor monomer of various shapes and specifications, and lithium-ion capacitor monomer system integration module; Downstream is mainly the application demand of the terminal market. At present, the Japanese market is initially open, and will be expanded in the international market, such as wind power generation, LED street lighting, solar power generation and hybrid electric vehicles. Typical application fields: applicable to power type power supply system fields such as passenger car energy storage, passenger car start and stop, smart grid, port and heavy machinery, standby power supply, etc.
