Advantages of lithium batteries: 1. Lithium batteries have a high-voltage platform. The average voltage of a single battery is 3.7v or 3.2v, which is approximately equal to the series voltage of three nickel-cadmium batteries or nickel-metal hydride batteries, which is conducive to the formation of battery power groups. 2. Compared with batteries, lithium batteries have a higher energy density. It has a high energy storage density, reaching 460-600wh/kg, which is about 6-7 times that of lead-acid batteries. 3. Compared with lead-acid batteries, lithium batteries are lighter, about 1/5-6 of the same volume of lead-acid products. 4. Lithium Battery has a long life, and the service life can reach more than 6 years. As a positive electrode battery, lithium iron phosphate has 1CDOD charge and discharge, and it has 1,000 use records. 5. Lithium iron phosphate batteries for electric vehicles have high power carrying capacity and can reach a charge and discharge capacity of 15-30c, which is convenient for high-intensity startup and acceleration. 6. Low self-discharge rate and no memory effect. It is often used for power supply of daily electronic products. 7. Lithium battery has strong adaptability to high temperature and low temperature. It can be used in the environment of -20℃-60℃, and can be used in the environment of -45℃ after processing. 8. Green and environmental protection, no matter it is produced, used or scrapped, it does not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium.
Disadvantages of lithium batteries:
1. The safety of lithium batteries is poor and there is a danger of explosion. 2. Lithium batteries made of lithium cobalt oxide cannot be discharged under high current, and their safety is poor. 3. The lithium battery needs to protect the circuit to prevent the battery from overcharging and overdischarging. 4. High production requirements and high costs. How can I buy good quality lithium batteries? 1. Look at appearance To look at the appearance is to look at the appearance, craftsmanship, size and craftsmanship of the lithium battery. Check whether the shell stitch width is wide, whether there are burrs, whether there is oil stains, feel good, advanced technology and comfortable, after polishing, the rubber glazing material feels good, and the insulation performance is also strong. 2. See if the capacity is clearly marked Lithium batteries without a clearly marked capacity are likely to be garbage batteries reassembled from defective or recycled batteries. The market is flooded with many cheap lithium batteries, which are made from recycled batteries or disassembled batteries. Although they are cheap, they have a short lifespan and unstable quality. If used carelessly, they may damage the equipment or even cause an explosion. 3. Look at the protection circuit The characteristics of the lithium battery determine that the lithium battery must be added to the protective plate to prevent the lithium battery from overcharging, over-discharging and short-circuiting. If the lithium battery does not have the protective plate, there is a danger of deformation, leakage, and explosion. Faced with fierce price competition, battery packaging companies seek cheaper protection circuits, or simply do not use them, allowing explosive lithium-ion batteries to flood the market. Of course, consumers cannot judge from the appearance whether there is a protective circuit board, so it is best to choose a reputable merchant to buy. 4. Look at the brand There are many brands of lithium batteries, but it is difficult to see the quality from the appearance. In this case, everyone should do a little more homework before choosing, and check the manufacturer's information more online. Generally speaking, professional manufacturers are more reliable than small workshops, and experienced manufacturers are more reliable than novices. 
ZTTEK Lithium Ion Battery, dedicated battery manufacturing technology for many years, safe and stable, no explosion hazard, strong endurance, long-lasting power, high charging conversion rate, non-hot, long service life, durable, is a battery brand worth choosing .
