18650 battery 3500mah lithium

　　The difference between 18650 battery 3500mah lithium and lead-acid batteries

　　18650 battery 3500mah lithium and lead-acid batteries have advantages and disadvantages in the following aspects:

　　1. Weight energy density

　　At present, the energy density of 18650 battery 3500mah lithium is 200-260h/g, and that of lead-acid batteries is 50-70h/g. The weight energy density of 18650 battery 3500mah lithium is 3-5 times that of lead-acid batteries, which means that lead-acid batteries have the same capacity. 3-5 times that of 18650 battery 3500mah lithium, so 18650 battery 3500mah lithium have a greater advantage in energy storage technology.

　　2. Volume energy density

　　The relative volume density of 18650 battery 3500mah lithium is usually 30%, so at the same capacity, the volume of lithium-ion batteries is 30% smaller than that of lead-acid batteries.

　　3.Use cycle time

　　At present, the most popular raw material management systems are ternary and iron lithium. The frequency of the ternary power lithium ion cycle system is generally greater than 1,000 times, the frequency of the lithium ion phosphate battery cycle system is greater than 2,000 times, and the frequency of the lead-acid battery cycle system is only 300-350 times, so the life of lithium-ion batteries is 3-6 times that of lead-acid batteries.

　　4. Price

　　Currently, lithium-ion batteries are about three times more expensive than lead-acid batteries, but the fusion life cycle analysis and capital investment cost are the same, and the application cycle of lithium ion is still longer.

　　5. Applicability

　　Since the safety factor of 18650 battery 3500mah lithium is slightly weaker than that of lead-acid batteries, it is necessary to apply it in various safety protection tasks, such as to avoid damage to 18650 battery 3500mah lithium caused by external forces or safety accidents, because this may cause fire or explosion; at this stage The acceptability of 18650 battery 3500mah lithium is also very good, and 18650 battery 3500mah lithium are not inferior to lead-acid batteries.

　　6. my country’s positive policies

　　Because lead-acid batteries are in the production stage or used rechargeable batteries are severely damaged by the natural environment, the development trend of lithium-ion replacement of lead-acid batteries will become more and more obvious and further accelerated.

　　The difference between 18650 battery 3500mah lithium and lead-acid batteries:

　　1. Durability: Lead-acid batteries are generally deep charged and discharged within 400 times, have memory, and can be used within 2 years. Lead-acid batteries contain liquid, and it takes a while to recharge the battery and must be filled with liquid; unlike 18650 battery 3500mah lithium, their durability is stronger than lead-acid batteries and their costs are lower. Deep batteries can be charged and discharged more than 500 times and have no memory. Their general lifespan is 4 to 5 years.

　　2. Volume and mass: Lead-acid batteries are larger in size. Net weight is usually 16-30kg. In turn, lithium-ion batteries generally have a much lighter net weight than lead-acid batteries, most of which are above and below the kilogram mark. And not much. Very easy to transport.

　　3. Production and manufacturing process: Lead-acid batteries have environmental pollution during the production and manufacturing process. If they are purchased improperly, they will also cause environmental pollution. Environmental protection is a very serious hazard. Lithium is relatively less carbon-friendly.

　　4. Price level: Many main manifestations of lithium-ion fusion are better than lead-acid batteries in all fields, but the price level is slightly higher than lead-acid batteries. This is also inevitable.
