The reaction in the process of lithium battery charge and discharge
lithium battery pack with lead-acid batteries is now the most frequently used on uninterrupted power supply batteries store energy. In the lead-acid battery exists in the uninterrupted power supply has been used to the present power battery, and lithium battery pack pack is developed in recent years, a short time in contrast to lead-acid battery power battery has more advantage. Then today we take a look at the reaction in the process of lithium battery charge and discharge.
cobalt acid lithium batteries of cobalt acid lithium chemical formula for LiCo02, is a kind of inorganic compounds, usually as the positive electrode of lithium-ion batteries. LICO02 L ion battery cathode material is a kind of high performance liquid phase formation process, the present stage by lithium magnesium aluminate obtained in lithium ion battery, respectively with acrylic emulsion or polyethylene glycol (PEG) solution for organic solvent, in PVA or PEG solution dissolve lithium salt and salt drilling, condensed to form gel after heating, the formation of gels in heating break down again, then calcined at high temperature, the fire of the powder grinding and sieving can be drilled acid lithium powder.
the effects of lithium battery charging and discharging process:
when charging reaction: the positive: LiCoO2 = Li1 - xCo02+xLi++xe- Negative: 6 c + xLi++ xe - =Lixc6。
when the discharge reaction: the positive: Li1 - xCoO2+xLi++xe- = LiCoO2 cathode: LixC6 = 6 c + xLi++ xe - 。
the advantages and disadvantages of cobalt acid lithium batteries lithium batteries:
the advantages of lithium battery:
1. Good production and processing and processing characteristics. With lead-acid batteries, in contrast, phosphate lithium battery charging rate nature also is a good point. Phosphoric acid lithium battery pack charging rate is 10 times that of lead-acid battery, a reasonable on the big stage greatly save the communication signal tower storage battery charging time switch. According to the investigation and research report, phosphate lithium battery as a kind of power battery, and can also be stored in a trough in the evening, in broad daylight in the peak period, the complete filling peak, further promote greatly reduced communication towers electricity
2. High density of vibration helps to improve the volume ratio of rechargeable batteries.
3。 Merchandise features stable and consistent. Unity means that the mass of lithium battery can also produce manufacturing, lithium battery pack production process is developed for so many years already.
4。 High working frequency, charge and discharge is stable, the advantages of high energy density and good recycling area is small, convenient to install and use.
5。 Suitable for large flow of charging and the placement of lithium ion battery and slip. With lead-acid batteries, in contrast, phosphate lithium battery charging rate nature also is a good point. Phosphoric acid lithium battery charging rate is 10 times that of lead-acid battery, a reasonable on the big stage greatly save the communication signal tower storage battery charging time switch. According to the investigation and research report, phosphate lithium battery as a kind of power battery, and can also be stored in a trough in the evening, in broad daylight in the peak period, the complete filling peak, further promote greatly reduced communication towers electricity bills.
lithium battery pack pack and what is the difference between lead-acid battery
1. Volume weight
under the same volume, the volume and weight of the lithium battery pack for lead acid, one of the three points can be effective and reasonable save installing space, more help to space planning, help to standardized management, reduce operational costs. In the whole process of battery charging, the structure of the active material through several times changed after convergence and continues to rise, causing lico0. Internal resistance increases, the volume reduced
2. Material composition
the lithium battery pack is normally USES lithium alloy metal oxide anode material, graphite as the cathode material, using nonaqueous electrolyte battery. Lead-acid battery is a kind of electrode is mainly composed of lead and its oxide, electrolyte battery is a sulfuric acid solution. pack the composition of the material in contrast to lead-acid battery has a lot of advantages on safe environmental protection, if happen again lithium battery pack, leakage, leakage of liquid nor the related staff and the surrounding environment form a larger threat.
