Product introduction:
An ultra-fast lithium ion module includes a harness board assembly and five core modules. The harness board assembly includes a harness board, an FPC board, a serial bar, a positive connector and a negative connector. The serial bar is connected in series with the adjacent core modules. The positive connector and the negative connector are respectively connected with the core module bus bar located outside the module; The FPC board is fixedly connected with the harness board; The harness board is provided with a through hole matching with the serial row, and the outer baffle of the through hole is provided with a notch. The sampling head of the FPC board is threaded in a notch and connected with the serial row, positive connector and negative connector. The central wire harness board, FPC board and serial row, positive connector and negative connector of the cylindrical lithium-ion battery module are connected stably and fully. The harness board assembly is compact in structure, with a small number of parts, which is convenient for automatic assembly. (1) 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.
(1) 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.
(2) 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.
(3) 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 in the case 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.
