What is the life span of high-temperature lithium iron phosphate and lithium-ion batteries? Lithium iron phosphate batteries are resistant to high temperatures, and the thermal peak of lithium iron phosphate batteries can reach 350 to 500 degrees Celsius. The operating temperature of conventional lithium-ion batteries: -20℃～60℃, but generally below 0℃, the performance of lithium-ion batteries will be reduced, and the discharge capacity will be reduced accordingly. Therefore, the full operating temperature performance of lithium-ion batteries is generally 0 ～40℃.
How long is the life of a high-temperature lithium-ion battery?
The high-temperature lithium-ion battery has a service life of only two to three years.
High-temperature lithium-ion batteries can generally be charged and discharged 300-500 times. It is better to discharge the lithium ion battery partially rather than completely, and try to avoid frequent full discharge. Once the battery leaves the processing line, the clock will start to move. Whether you use it or not, the life of a lithium-ion battery is only two to three years.
The high-temperature-resistant lithium-ion battery can withstand temperatures up to 800 degrees. Lithium-ion batteries can generally withstand high temperatures such as 200 degrees, 500 degrees and 800 degrees, but under normal circumstances, we will not be exposed to such high temperatures in our daily lives, but we can often see charging. Or when the device is overused, the battery is damaged.
High-temperature lithium-ion batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and can be recharged. The fifth-generation rechargeable battery-lithium metal battery was born in 1996, and its safety, specific capacity, self-discharge rate and cost performance are better than lithium-ion batteries. Due to its own high-tech requirements, only a few companies in a few countries are currently producing these lithium metal batteries.
Some large electrical appliances and equipment must withstand high-temperature lithium-ion batteries. Because lead acid is not environmentally friendly, its energy density is low, its volume is large, its lifespan is short, and its weight is large. At present, new products developed by merchants or batteries for transformation and upgrading basically use high-temperature lithium-ion batteries as an important power source for equipment.
In order to ensure the durability and safety and reliability of lithium-ion batteries, high-temperature-resistant lithium-ion batteries will use advanced protection management systems in their batteries to protect themselves from overcharging , Excessive discharge, high temperature operation and low temperature. Charging or short-circuit damage, or even safety issues.
High temperature resistant lithium-iron-phosphate battery life
Lithium iron phosphate battery is a type of lithium ion battery, which refers to a lithium ion battery that uses lithium iron phosphate as the positive electrode material. It is characterized by high safety and stability, high temperature resistance, and good cycle performance.
Like a ternary lithium-ion battery, a lithium phosphate battery has a theoretical service life of more than 2000 charge and discharge cycles, and it can last for more than five years even if it is charged once a day. Generally speaking, the daily household electricity is 3 days, and it can be used for about 8 years. However, due to the poor low-temperature performance of lithium iron phosphate batteries, the service life of lithium iron phosphate batteries in the southern region will be relatively long.
Compared with the ternary lithium-ion battery, it has the advantage of high temperature resistance. The high-temperature performance of lithium iron phosphate batteries is better and can withstand high temperatures from 350°C to 500°C, while lithium manganate/lithium cobalt oxide batteries are usually only about 200°C. The materials of the improved ternary lithium-ion battery pack are roughly the same. The analysis will be performed at 200°C.
Lithium iron phosphate batteries have a longer life span than lead-acid batteries and ternary lithium-ion batteries. The "long life" of the lead-acid battery is only about 300 or 500 times; the ternary lithium-ion battery can theoretically reach 2000 times, and the capacity will drop to about 60% after the actual use of about 1000 times; while the real lithium iron phosphate battery The life span reaches 2,000 cycles, and the current capacity is 95%, and its conceptual life span reaches more than 3,000 cycles.
The above is the service life of the high temperature resistant lithium iron phosphate battery. High-temperature lithium-ion batteries can generally be divided into five grades, which are used above 100°C, 125°C, 150°C, 175°C, and 200°C. Among all electrochemical systems, these two systems have the longest storage time and the highest working voltage.
