Why is there such a big difference between these two lithium battery packs?
Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The rise of the new energy vehicle industry has expanded the market demand for lithium-ion battery packs, making them scarce and causing their prices to rise steadily.
In short, lithium battery packs have significant advantages over domestic manufacturers in terms of battery consistency, stability, safety, environmental friendliness, and cycle life, making them very attractive to downstream manufacturers.
Lithium battery packs have a wide range of applications: small computer rooms, low-voltage rooms and other indoor distributed systems, new energy outdoor sites, communication base stations, indoor and outdoor sites without air conditioning, broadcasting, special, petroleum and meteorological unmanned sites are all applicable scenarios.
Compared to other lithium battery packs on the market, its features and advantages are:
1. Energy density: In the same volume, the energy density of lithium-ion batteries is 3 to 4 times that of lead-acid batteries, 2.5 times that of nickel-cadmium batteries, and 1.8 times that of nickel-metal hydride batteries. Therefore, with the same battery capacity, lithium-ion batteries will be smaller and lighter than lead-acid, nickel-cadmium, and nickel-metal hydride batteries.
2. Long lifespan: Lead-acid batteries have a cycle life of around 300 cycles. In contrast, lithium iron phosphate batteries, at room temperature and 1C charge/discharge, retain more than 80% capacity after 2000 cycles, and their 3C cycle life exceeds 800 cycles.
3. High-rate discharge: The discharge rate can still reach 90%.
4. Fast charging: It can be charged and discharged at a high current of 2C. With a dedicated charger, the battery can be fully charged in 40 minutes at 1.5C. The starting current can reach 2C, which is a feature that lead-acid batteries do not currently have.
5. Safety: Safety comes from the stability of the cathode material and the reliable safety design. Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganese oxide. Lithium cobalt oxide and lithium manganese oxide will explode under strong collision, while lithium iron phosphate has undergone rigorous safety testing and will not explode even in violent collision.
6. Environmental protection: Lithium iron phosphate materials do not contain any heavy metals or rare metals, are non-toxic, and cause no pollution during production and use. They comply with European RoHS regulations and are green and environmentally friendly batteries.
7. No memory effect: When rechargeable batteries are frequently operated under conditions where they are fully charged but not fully discharged, their capacity will rapidly drop below the rated capacity. This phenomenon is called the memory effect. Lithium iron phosphate batteries do not have this phenomenon. Regardless of their state, the battery can be charged and used immediately without needing to be fully discharged before recharging.
With policy support, and given the strong national push for the development of new energy vehicles, combined with the inherent characteristics of lithium batteries such as being pollution-free and having high energy storage efficiency, my country's production and sales of new energy vehicles are showing a clear upward trend, and industry demand is booming. As a key application area for power lithium battery packs, the development needs of the new energy vehicle industry will have a significant impact on JUD lithium battery packs, driving an explosive growth in lithium battery pack sales.
