The battery life is different and the chemical composition is different.
1. 811 has high energy density and long service life, and is widely used in new energy vehicles. Its advantages are relatively high energy density and low cost, while 523 has lower energy density. , but the cost is relatively low. 523 batteries are mainly used in some economical new energy vehicles.
2. 811 battery refers to a type of lithium-ion battery, where 8 represents the chemical composition of the cathode material, namely lithium-nickel-manganese-cobalt (NMC) battery is also a lithium-ion battery. battery. One type, where 5 represents the chemical composition of the cathode material, namely lithium manganate (LMO).
How good are Huyan lithium batteries?
There is no doubt that lithium batteriesTianneng lithium batteries for electric vehicles are better, while Chaowei lithium batteries are average.
In 2019, Tianneng Lithium Battery and French global lithium battery giant SAFT established a joint venture, using its core technology to better ensure the safety of lithium batteries.
With the support of safety core technology, Tianneng Lithium Battery launched super lithium iron manganese battery in 2020. This super lithium iron manganese battery adopts advanced material technology independently developed by Tianneng Lithium Battery and combines the advantages of the three major technical systems of NCM, LFP and LMO. It has high energy, high throughput and high security, truly realizing "iron-lithium level security, ternary level energy".
The battery core has passed many strict national certification tests such as overcharge, overdischarge.e, overcurrent, drop, hot box, extrusion, etc., and can even pass the industry ceiling-level safety test. - "acupuncture" During the experiment, there were no fires or explosions during the entire process. It can be said that "it is still strong despite being hit hard by winds from east to west, north and south."
The super powerful lithium iron manganese battery does not fear intense cold, scorching heat, wind, rain or bright sun. The battery has a 100% discharge rate at an ultra-high temperature of 55°C and can discharge over 85% in a low temperature environment of minus 20°C. The plastic housing features exclusive molding and color matching, complemented by. a new glue process, with super IP67 water resistance, beauty and strength, stable and safe.
Okay.
1. Huyan lithium batteries usedent a variety of cathode materials, such as lithium cobalt oxide (LCO), lithium manganate (LMO), lithium iron phosphate (LFP), and ternary materials. Among them, lithium cobalt oxide has the characteristics of high voltage, high density, stable structure and good safety, but the cost is relatively high; lithium manganate has low cost and high voltage, but its cycle performance and gram capacity are slightly lower.
2. Compared to traditional lead-acid batteries, lithium batteries are smaller and lighter. This is particularly evident in the new national standards for e-bikes. New national standards require that the mass of electric bicycles should not exceed 55 kg, and the battery voltage should not exceed 48 V, so lithium batteries have become the first choice.
3. The batteriesLithium batteries have a high energy density, which means they can store more electrical energy at the same time, their lifespan is relatively long.
