General
A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began researching lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. With the development of science and technology, lithium batteries have become the mainstream.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation lithium-metal battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate and performance price ratio are better than lithium-ion batteries. Due to its own high technical requirements, only a few companies in the country are producing such lithium metal batteries.
Product working principle
The working principle of lithium-ion battery refers to its charging and discharging principle. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon as the negative electrode has a layered structure, and it has many micropores. The lithium ions reaching the negative electrode are embedded in the micropores of the carbon layer, and the more lithium ions are embedded, the higher the charging capacity.
By the same token, when the battery is discharged (ie, the process we use the battery), the lithium ions embedded in the carbon layer of the negative electrode come out and move back to the positive electrode. The more lithium ions return to the positive electrode, the higher the discharge capacity. What we usually call battery capacity refers to the discharge capacity.
It is not difficult to see that during the charging and discharging process of a lithium ion battery, the lithium ion is in a state of motion from the positive electrode to the negative electrode to the positive electrode. If we compare the lithium-ion battery to a rocking chair, the two ends of the rocking chair are the two poles of the battery, and the lithium ion is like an excellent sportsman, running back and forth at both ends of the rocking chair. Therefore, the experts gave the lithium-ion battery a cute name rocking chair battery.
Product Features
1. The energy is relatively high. With high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries;
2. It has a long service life and can last for more than 6 years. Lithium iron phosphate is the positive battery 1C (100%DOD) charge and discharge, and can be used for 10,000 times.
3. High rated voltage (single working voltage is 3.7V or 3.2V), which is equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient for battery power packs; lithium battery can pass a new type of lithium battery regulator The technology, the voltage is adjusted to 3.0V, suitable for the use of small appliances.
4. With high power bearing capacity, lithium iron phosphate lithium ion battery for electric vehicles can achieve 15-30C charge and discharge capacity, which is convenient for high-intensity start-up acceleration;
5. The self-discharge rate is very low, which is one of the most outstanding advantages of the battery, generally can be 1% / month or less, less than 1 / 20 of the nickel-hydrogen battery;
6. Light weight, the weight of the same volume is about 1/6-1/5 of the lead acid product;
7. High temperature and low adaptability, can be used in the environment of -20 ° C - 60 ° C, after the process treatment, can be used in -45 ° C environment;
8. Green, no matter whether it is produced, used or scrapped, it does not contain any toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium.

- Q: Solar products must be in the sun
- Energy (Solar), generally refers to the sun's radiant energy, passive use (photothermal conversion)
- Q: How to promote the use of solar energy in China
- In this regard, the government should do a lot of work, industry associations have also made the relevant advance
- Q: What are the third generation solar cells
- The physical connotation contained in it is: should keep the advantages of the second generation thin film solar cell with low cost, and is much higher than the Shockley-Queisser limit (32.8%) high efficiency, stable and reliable performance and the battery and battery rich material sources. In other words, the so-called third generation solar cell is a kind of high efficiency, low cost, long life, non-toxic and high stability of the near ideal photovoltaic solar cells."
- Q: Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
- Mobile phone battery as an energy reserve, but no 5V output boost function, the same can not charge the phone. If you have bought a solar panel, you can buy a mobile power with the use of
- Q: How much does it cost to install solar energy in rural areas
- Two see insulation performance. The storage tank is a hot water storage tank, and its performance is mainly reflected in the insulation effect. Good insulation not only depends on the thickness of the insulation layer, but also insulation materials and processes. The use of automatic numerical control constant temperature and constant pressure quantitative foam, high temperature curing, thickening insulation layer of the water storage tank to ensure that the layer is more compact symmetry, thermal insulation performance is more durable.Three see bearing strength. Like the solar stent skeleton, of course not fragile. At present, there is a more streamlined tower support, which uses reinforced, super high base, to overcome the traditional thin rod bracket thin wind resistance of the problem, wind, rain, hail, corrosion resistance.
- Q: Now there is no sun, cloudy days can use solar products?
- At present, I have not found this kind of solar energy
- Q: Solar panels with single crystal silicon or good thanks
- The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.
- Q: Are solar panels now in use?
- Generally through the position, speed and torque in three ways to control the servo motor to achieve high-precision positioning of the transmission system, the transmission technology is the high-end products.
- Q: Monocrystalline silicon market when the turnaround, to what extent
- From the current technology development and application prospects, I believe that solar energy has the most opportunity to become the world's major alternative energy sources. 1, the whole world light is rich in resources, solar energy is inexhaustible, inexhaustible solar energy; 2, technology and talent in the world of IT technology talents emerge in an endless stream, transferred to the solar technology, solar photovoltaic industry and the IT industry is very similar to that of solar grade polysilicon and electronic grade polycrystalline silicon thin film technology is the extension of a. From the LCD technology, therefore, the solar photovoltaic technology upgrading is very fast, the power generation efficiency of photovoltaic cells is also more and more high, more and more low cost at the same time, smart grid and energy storage technology will further enhance the application of solar energy, the development of space is very large, and is not affected by resource constraints and resource prices, if a stable price support, can maintain long-term fixed income, therefore, the solar power industry as the development of financial products, insurance funds will be favored;
- Q: The steps of making solar technology stubs
- Step:1, the walnut tip toward the fire on the fire for a while, and then thrown into the cold water, walnut will split along the seam.2, the suture will break the walnut into two halves.
