The same is the lithium battery pack, why is the difference in energy storage so large?

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. The rise of the new energy auto industry has expanded the market demand for lithium battery pack resources, and the lithium battery pack has also become tight, making the price of lithium batteries climb.

However, the energy storage lithium battery pack has not been affected, but the order volume is increasing, and the purchasers are coming. Why is this?

In a word, the energy storage lithium battery pack has a relatively large advantage in terms of battery consistency, stability, safety, environmental protection, cycle life, etc., compared with domestic manufacturers, and is also attractive to downstream manufacturers. .

The energy storage lithium battery pack has a wide range of applications: small computer rooms, weak room rooms, new energy outdoor sites, communication base stations, indoor and outdoor airless sites, radio and television, military, oil and meteorological unmanned sites are all applicable scenes.

Compared to other lithium battery packs on the market, his features are:

1. Energy density: Under the same volume, the energy density of lithium-ion battery is 3~4 times that of lead-acid battery, 2.5times that of nickel-cadmium battery, and 1.8 times that of nickel-hydrogen battery. Therefore, when battery capacity is equal, lithium-ion batteries are smaller and lighter than lead-acid, nickel-cadmium, and nickel-metal hydride batteries.

2. Long life: lead-acid battery cycle life is about 300 times. The lithium iron phosphate power battery is charged and discharged at room temperature 1C, the capacity of the monomer is still greater than 80% after 2000 cycles, and the cycle life of 3C is more than 800 times.

3. High rate discharge: The discharge rate can still reach 90%.

4. Fast charging: high current 2C fast charge and discharge, the battery can be fully charged within 1.5 minutes of 1.5C charging under a dedicated charger, the starting current can reach 2C, and the lead-acid battery does not have this performance.

5. Safety: Safety comes from the stability of the positive electrode material and reliable safety design. lithium iron phosphate completely solves the safety hazard problem of lithium cobaltate and lithium manganate. Lithium cobaltate and lithium manganate will under strong collision. An explosion occurs, and lithium iron phosphate has undergone rigorous safety testing, and will not explode even in severe collisions.

6. Environmental protection: lithium iron phosphate material does not contain any heavy metals and rare metals, non-toxic, no pollution in production and use, in line with European RoHS regulations, is a green battery.

7. No memory effect: Rechargeable batteries are often operated under conditions of full discharge, and the capacity will quickly fall below the rated capacity. This phenomenon is called memory effect. lithium iron phosphate battery does not have this phenomenon, and the battery can be used as it is, regardless of the state, without first discharging it completely.

Policy support: at present, lithium battery packs combine the characteristics of lithium batteries with no pollution and high energy storage efficiency in the context of the country's strong development of new energy vehicles. China's new energy vehicle production and sales have an obvious upward trend, industry demand is strong, new energy vehicles as a new energy vehicle The important application areas of the power lithium battery pack, its industry development needs will have a greater impact on the storage of electrical lithium battery packs, will drive the sales of lithium battery packs to explode.
