Description
Technical field
The present invention relates to a kind of preparation method based on lithium-ion capacitor and lithium battery hybrid energy-storing monomer, this energy storage monomer is by lithium positive pole, carbon positive pole and Carbon anode and form containing the non-aqueous organic solvent of the lithium ion moved freely.In a construction unit, the high-rate characteristics of ultracapacitor and the high capacity characteristics of lithium ion battery can be realized simultaneously.
Background technology
High-energy-density, high power density, wide temperature range and long circulation life are developing direction and the scientific research target of mechanism of new electrochemical power sources.
Lithium ion battery and ultracapacitor represent the developing direction of mechanism of new electrochemical power sources, and in all business-like chemical power sources, lithium ion battery has the feature of high-energy-density.
The main application fields of lithium ion battery includes energy type (be mainly used in mobile phone, removable computer is the digital product of representative), and power type (electric tool, hybrid electric vehicle, electric bicycle, electric automobile).Along with the progressively development of material technology and battery design technology, lithium ion battery is more extensive in the application of dynamic field, although lithium ion battery obtains important breakthrough in high magnification, but due to lithium battery be by lithium ion between both positive and negative polarity repeatedly deintercalation realize energy storage process, so lithium battery capacity attenuation in long-term high rate cyclic process is rapid, and capacity attenuation is also very fast under cryogenic.
Ultracapacitor is a kind of novel energy device, traditional ultracapacitor utilizes the electric double layer formed on both positive and negative polarity carbon electrode material surface to realize energy storage process, and the energy density of ultracapacitor depends on specific capacitance and the stable potential window of electrode material.
Because ultracapacitor realizes energy storage process by forming electric double layer at electrode surface, due to do not exist ion electrode material body mutually in embedding and deviate from and cause electrode material structure collapses, therefore, compared with lithium ion battery, ultracapacitor has the feature of high cycle performance, high power characteristic and wide temperature range.Energy storage mode due to ultracapacitor is electric double layer energy storage, the ion concentration of electrode material inside is very low, the potential window lower (1-2.7V) of ultracapacitor simultaneously, the energy density determining ultracapacitor is very low, be about 1/10 of lithium ion battery, how to improve the energy density of ultracapacitor, become the focus of Recent study.
For improving the energy density of ultracapacitor, mainly realized by the stable potential window of the specific capacitance and raising capacitor that improve electrode material, but the metal oxide electrode of high-specific capacitance super (as rhodium oxide, manganese oxide and cobalt oxide) needs to realize energy storage in water solution system, so limited to the raising of potential window usually; And adopt the mode of asymmetric capacitor (very metal oxide, another very absorbent charcoal material) although the energy density that improve ultracapacitor to a certain degree, but because stable potential window improves still more limited, simultaneously because metal oxide electrode is in the unsteadiness of course of reaction structure, so cycle life declines greatly.
Lithium-ion capacitor is a kind of positive pole asymmetric capacitor different from negative pole charge-discharge principle, have employed the principle of double electric layer capacitor in design, constructively have employed the combination of the negative material of lithium ion battery and the positive electrode of double electric layer capacitor, with the addition of lithium ion at negative pole again simultaneously, thus substantially increase the energy density of capacitor.
The lithium-ion capacitor having patent to mention with high-specific surface area material with carbon element be positive pole, graphite is for negative pole, prepare lithium-ion capacitor, at capacitor internal by metal lithium sheet to the pre-embedding lithium of graphite, the maximum potential window between lithium capacitor positive and negative plate can reach 4.35V.But the unsteadiness of lithium sheet and easily oxidizable, the moisture easily and in air and oxygen generation chemical reaction are so when introducing the operation of lithium electrode, need to carry out in the external environment of anhydrous and oxygen-free, higher to suitability for industrialized production environmental requirement.Cause the assembling process of capacitor very difficult.
For novel energy-storing device, wish to have concurrently simultaneously high-energy-density, high power characteristic, long-life and wide temperature range feature, for realizing the requirement of energy storage device at different-energy density and multiplying power discharging, technology is had to propose ultracapacitor and lithium battery to carry out " loong shunt ", lithium ion battery is used when needs energy storage, use ultracapacitor when needs multiplying power discharging, but thisly multi-functionally can not to realize in an energy storage monomer.Loong shunt implementation can cause protecting circuit designed comparatively complicated.
