Lithium batteries which are the advantages and disadvantages, how to buy good quality lithium battery?

Source: 2020 - 03 - 29 behold their hits: what are the pros and cons first lithium battery, how to buy good quality lithium battery? 1. Lithium battery has high voltage channel, a single uniform battery voltage is 3. 7 v or 3. 2 v, is approximately equal to three pieces of nickel cadmium battery or nickel metal hydride batteries in series voltage, is advantageous to the formation of battery power. 2. Compared with batteries, lithium batteries with higher energy density. It has the very high energy storage density, 460 - 600 wh/kg, which is about 6 - of lead-acid batteries Seven times. 3. Compared with lead-acid batteries, lithium batteries are lighter, about 1/5 of the volume, lead acid products 6. 4, lithium battery life is long, life can use 6 years, in the lithium iron phosphate batteries, with one cdod charge and discharge, has a record with 1000. 5. Electric cars iron phosphate lithium-ion battery with high power capacity, can reach 15 - 30 c to charge and discharge capacity, facilitate high strength starting and accelerating. 6. Low self-discharge rate, no memory effect, often used in daily electronic products of power supply. 7. Lithium battery for high and low temperature adaptability is strong, can be in - 20℃- Using 60 ℃ environment, can be in - after processing Use in 45 ℃ environment. 8, green environmental protection, regardless of the production, use, scrap, and do not contain, does not produce any poisonous and harmful heavy metals such as lead, mercury, cadmium and material. 1 to the defects of lithium battery. The lithium battery security is poor, with explosion danger. 2. Made of lithium cobalt acid lithium batteries in the big electricity flow can't discharge, poor safety. 3, lithium battery needs protection circuit to prevent the battery overcharge and over discharge. 4. High production requirements, cost is high. How can I buy some good quality lithium battery? 1. The appearance of the surface is the appearance of the lithium battery, technology, size and technology. Whether the width of the shell seam width, whether to have burrs, with or without oil, feel is good, the craft is advanced, very comfortable, after polishing, rubber varnish information feel is good, have very strong heat preservation function. 2. See if there is a clear no clear capacity marking capacity of lithium battery is likely to be defective or recycled by battery waste batteries have been assembled from scratch. Is everywhere in the shop cheap lithium ion battery recycling or removed. Though they are so cheap, but their lifespan is short, the quality is not stable, if not careful, it might damage the equipment or even explode. 3. Look at the characteristics of lithium battery protection circuit selection on lithium battery is necessary to add to the protection board, in order to prevent the lithium battery overcharge, over discharge and short circuit conditions such as attack, such as lithium battery without protection board will have deformation, the danger of leakage and explosion. In the face of fierce price competition, battery packaging company is looking for a cheaper protection circuit, may not use them, let the explosive lithium-ion battery flooding the market. Of course, the customer can't judge from appearance whether there is a protection circuit board, so it's best to choose reputable stores to buy. 4. A lot of brand watch brand lithium battery, but it's hard to see from the appearance quality. In this case, we should choose to do more homework before, more than the search manufacturer information on the Internet. In general, professional manufacturer is more reliable than small workshops, experienced manufacturer is more reliable than novices.
