35Ah Ultra-Low Temperature LiFePO4 Battery – -40°C Discharge, 3000 Cycles, 25C Pulse for Extreme Cold Energy Storage

Product Overview – Ultra-Low Temperature LiFePO4 Battery

PPCELL’s 35Ah ultra-low temperature LiFePO4 battery cell (Model P‑80F3b0) is a high-performance lithium iron phosphate cell specifically engineered for extreme cold environments. Leveraging a proprietary nano-LiFePO4 + fast-charging graphite material system, this soft-pack cell delivers an industry-leading combination of ultra-low temperature performance, cycle life, and power capability.

With a nominal voltage of 3.2V, 35Ah capacity, and 150Wh/kg gravimetric energy density, the P‑80F3b0 is optimized for energy storage systems operating in sub-zero conditions. The ultra-thin 8.0mm profile and 286Wh/L volumetric energy density enable compact battery pack designs for space-constrained applications. Nano-LiFePO4 cathode technology provides superior low-temperature ionic conductivity compared to standard LFP materials, ensuring reliable performance even at -40°C.

The cell supports 12C continuous discharge (420A) and 25C pulse discharge (875A), delivering the instantaneous power required for cold-start applications and high-load equipment. Ultra-low internal resistance (≤1.0mΩ) minimizes heat generation during high-rate discharge, improving both efficiency and safety.
