Abstract
The invention relates to a battery, and in particular, relates to an electrolyte solution of the battery. A CR2450 lithium-manganese dioxide battery applicable in a refrigerated working environment includes the electrolyte solution; spherical particles formed by injection molding of a polyamide 66 material are added in the electrolyte solution. In a -2 to 8 DEG C cold environment for a long time, a product adopting the electrolyte solution of the formula has the working time about 10% longer than a general CR2450 battery, and can effectively reduce material cost and labor cost of battery replacement.
Description
Technical field
The present invention relates to a kind of battery, particularly relate to the electrolyte solution of a kind of battery.
Background technology
Disposable button cell relatively common in the market, essentially lithium manganese dioxide cell, lithium-manganese dioxide battery negative pole is lithium metal, and positive pole activity material is electrolytic manganese dioxide.Electrolyte is inorganic salt lithium perchlorate (LiClO4), be dissolved in Allyl carbonate (PC) and 1, in the mixed organic solvents of 2-dimethoxy-ethane (DME), its chemical expression is:
(-) Li/LiClO4 PC+DME/MnO2 (+) battery cathode reaction: Li → Li++e positive pole reacts: MnO2+Li++e → MnO2 (Li+) overall reaction: Li+MnO2 → MnO2 (Li+).
The result of use of this battery is better, and due to manganese dioxide aboundresources, low price, is suitable for a large amount of production.In cold chain storage and cold chain transportation process, have some Sensor monitoring temperature, humidity, the environmental variables such as intensity of illumination, and by the mode of less radio-frequency, these environmental variables are transferred out, these sensors are generally packaged in inside product package interior or refrigerator car, external power source cannot be used to power, disposable battery generally can be used as power supply, the duty of this sensor is, environment is sampled by interval, wireless data transmission, in sampling and transmitting procedure, electric current is approximately in 15～30mA, persistent period is approximately 10ms～50ms, it is spaced apart 1min～10min every time, general CR2450 button cell is in the environment of-2 DEG C～8 DEG C, the electric energy that can release is generally 80% during equal discharging model 20 DEG C.Electrolyte is non-hydrolytic organic electrolyte, thus the viscosity of electrolyte can increase under cryogenic, thus affecting performance, it is desirable to have certain catalyst keeps the activity of electrolyte in above-mentioned scene.
Summary of the invention
The technique effect of the present invention can overcome drawbacks described above, it is provided that a kind of lithium manganese dioxide cell suitable in cold preservation working environment, it greatly improves electrolyte solution activity under low temperature state.
For achieving the above object, the present invention adopts the following technical scheme that it includes electrolyte solution, adds the spheroidal particle that polyamide 66 injection molding becomes in electrolyte solution.
The present invention, by adding polyamide granules in battery electrolyte, plays the effect of catalyst at low ambient temperatures, makes discharge capability in the environment of-2～8 DEG C reach more than the 90% of 20 DEG C.
Preferably, polyamide granules adopts polyamide 66 material injection molding globulate granule, the diameter of granule is 0.1mm～0.2mm, heat conductivity>20W/ (m K) (method of testing ASTME1461), specific insulation<1.0E+2 Ω cm (method of testing ASTMD257), proportion 1.55-1.60g/cm3(ASTM792).In the electrolytic solution, add ratio mixed electrolytic solution and the catalyst of 45-55g material in 1L, and in the environment of-20 DEG C, carry out uniform stirring, mixing time 3min.
In being chronically at the cold storage environment of-2～8 DEG C, the product using this formula electrolyte is longer by about 10% than general CR2450 battery working time, it is possible to effectively reduce the Material Cost and cost of labor of changing battery.
