Austria lithium iron phosphate battery site cabinet attenuation

After 150 cycles of testing, its capacity retention rate is as high as 99.7 %, and it can still maintain 81.1 % of the room temperature capacity at low temperatures, and it is effective and universal. This new strategy improves the low-temperature performance and application range of lithium iron phosphate batteries.

Lithium iron phosphate battery works harder and lose the vast majority of energy and capacity at the temperature below −20 ℃, because electron transfer resistance (Rct) increases at low-temperature lithium-ion batteries, and lithium-ion batteries can hardly charge at −10℃. Serious performance attenuation limits its application in cold environments.

In this paper, according to the dynamic characteristics of charge and discharge of lithium-ion battery system, the structure of lithium iron phosphate is adjusted, and the nano-size has a significant impact on the low-temperature discharge performance.

Compared with the research results of lithium iron phosphate in the past 3 years, it is found that this technological innovation has obvious advantages, lithium iron phosphate batteries can discharge at −60℃, and low temperature discharge capacity is higher.

At HIS-Energy our aim is to deliver our clients with fully integrated turnkey battery storage solutions. HISbatt 215-A comes with an integrated cooling system (HVAC), a fire suppression system, and a power inverter installed with the safest LFP battery cells.

However, its energy conversion and storage capacity decay rapidly at low temperatures (below 0 ℃), resulting in degradation or failure of battery performance, increasing the use cost and risk of lithium-ion batteries, reducing energy utilization, and seriously hindering the promotion and development of lithium-ion batteries, .
