Description
NEGATIVE PRESSURE STEPPED FORMATION METHOD OF LI-ION CAPACITOR BATTERY Technical Field of the Invention The present invention relates to the technical fields of Li-ion batteries, in particular to a negative pressure stepped formation method of a Li-ion capacitor battery. Background of the Invention Li-ion batteries are green secondary batteries having large energy density, high average output voltage, small self-discharge and no toxic substances. After almost 20 years of development, Li-ion batteries can already reach 100 Wh/kg to 150 Wh/kg, and the working voltage can reach 4V at maximum. As energy storage devices based on an electric double-layer power storage principle and an redox pseudo-capacitance principle with high reversibility, super capacitors have the advantages of high power density, short charge/discharge time, long cycle life, wide operating temperature range and the like. However, such super capacitors have the disadvantages of relatively low energy density or the like. The difference in specific energy and specific power between the Li-ion batteries and the super capacitors determines the difference in their charge/discharge rate. In practical applications, as super capacitors and Li-ion batteries have respective prominent advantages and limitations, the application of parallel or serial capacitor batteries combining the both makes up this blank. Due to their prominent characteristics, Li-ion capacitor batteries are often applied in power sources and other related fields. In practical applications, the power sources face the problems of heavy-current charge and repeated charge/discharge. For capacitor batteries which are in heavy-current charge for a long term, it is often likely to cause the irreversible redox reactions of few 1 oxygen-containing functional groups in the active carbon and the decomposition of electrolyte, thereby resulting in a part of gas in the batteries. If this part of gas is not removed in time, the performance of a battery will be influenced, and the battery will be expanded seriously even to damage the structure of the battery. During the prefabrication of a capacitor battery, formation is a very important step. During the formation, a passivation layer (an SEI film) is formed on the surface of a cathode. The degree of the formation of the SEI film directly influences the stability, service life, safety and other factors of the battery. The conventional long-time and low-current formation method is time-consuming, and also will increase the impedance of the SEI film for a capacitor battery having a higher operating voltage, thereby influencing the rate performance of the capacitor battery. Summary of the Invention An objective of the present invention is to provide a negative pressure stepped formation method of a Li-ion capacitor battery, in order to change the present situation of following the conventional formation method of Li-ion batteries and to explore and seek optimal formation methods suitable for different capacitor batteries. Due to different redox potentials generated by different Li-ion battery anodes and cathodes used in different capacitor batteries, as well as different doping ratios of anode to cathode for composite anodes and cathodes, it is required to provide different formation solutions. To achieve the above inventive objective, the present invention employs the following technical solutions. A negative pressure stepped formation method of a Li-ion capacitor battery is provided, specifically including the following steps of: packaging a PP pipe 20 mm in length and 5 mm in diameter as a liquid injection port connected to a vacuum pump when packaging a capacitor battery cell, 2 injecting liquid into the battery cell and standing for 18±4h, determining a charge/discharge potential according to redox potentials of an anode and a cathode, forming with current of difference sizes by stepped charge/discharge cycles, and meanwhile connecting the PP pipe to the vacuum pump to keep a degree of vacuum of -0.5 Mpa, wherein the specific voltage and current in different stages are as follows: a first stage: the starting voltage is an initial voltage, the cut-off voltage is U1, and the current is 0.02-0.05C; a second stage: the starting voltage is a lower operating voltage limit, the cut-off voltage is U2, and the current is 0.05-0.1C; a third stage: the starting voltage is the lower operating voltage limit, the cut-off voltage is U3, and the current is 0.1-0.2C; a fourth stage: the starting voltage is the lower operating voltage limit, the cut-off voltage is U4, and the current is 0.1-0.2C; and a fifth stage: the starting voltage is the lower operating voltage limit, the cut-off voltage is U5, and the current is 0.1-0.2C; where U1<U2<U3<U4< U5=upper operating voltage limit. Preferably, the anode material of the capacitor battery comprises a mixture of active substance A and active substance B, the active substance A being one or a mixture of more of LiCO0 2 , LiMn 2 0 4 , LiMnO 2 , LiNiO 2 , LiFePO 4 , LiMnPO 4 , LiNio.

Compared with the prior art, the present invention has the following beneficial effects: (1) the formation method is efficient and quick; and (2) the present invention has broad applications. Brief Description of the Drawings Fig. 1 shows a charge/discharge curve of a formation process. Detailed Description of the Invention The technical solutions of the present invention will be further described as below by specific embodiments. Unless otherwise specified, all raw materials used in the embodiments of the present invention are commonly used in the art, and the methods used in the embodiments are conventional ones in the art. Embodiment 1 The formation process of an LFP-AC/MCMB flexibly packaged sample will be described. Fig. 1 shows a charge/discharge curve of the formation process. Composite anode material: LiFePO 4 , active carbon, a conductive agent and a binder are mixed in a mass ratio of 25:65:5:5 to obtain slurry, and then coating, rolling and slitting of electrode slices are performed, where the size of 4 each of the electrode slices is 75mm*56mm. Composite cathode material: MCMB, hard carbon, the conductive agent and the binder are mixed at a mass ratio of 50:40:5:5 to obtain slurry, and then coating, rolling and slitting of electrode slices are performed, where the size of each of the electrode slices is 75mm*56mm. A cell is obtained by stacking ten pairs of anode and cathode slices, separating by a three-layer polymer diaphragm PP-PE-PP and then drying for 24h at 60'C. Then, the cell is assembled, where a PP pipe 20 mm in length and 5 mm in diameter as a liquid injection port connected to a vacuum pump is packaged during packaging the cell. The capacitor battery cell is injected with liquid and kept standing for 18±4h. The PP liquid injection pipe of the obtained capacitor battery is connected to the vacuum pump to keep a degree of vacuum of -0.5 Mpa. The current and voltage of the staged formation are set according to redox potentials of the lithium iron phosphate and MCMB, specifically: Starting voltage (V) Cut-off voltage (V) Charge/discharge current (mAh) Initial voltage 2.7 5 (0.02C) 2.0 3.2 12.5 (0.05C) 2.0 3.4 25 (0.1C) 2.0 3.6 50 (0.2C) 2.0 3.8 50 (0.2C) The capacitor battery is subjected to performance tests after formed. After charged to 3.8V at 1 C and then discharged to 2.0V at 1 C, the capacitor battery has specific energy of 35.6 Wh/kg and specific power of 3800 W/kg. The capacity of the capacitor battery is kept at 82.3% after 15000 times of charge/discharge cycles at 1 C. It can be seen from the charge/discharge tests and the cycle performance that, the performance of the metal lithium salt of the Li-ion capacitor battery and the formation of the cathode SEI film may be greatly improved through the negative pressure stepped formation method, and the specific energy, specific power and cycle life of the resulting hybrid capacitor battery are significantly 5 enhanced.
