Product Overview – Ultra-Low Temperature LiFePO4 Battery
PPCELL’s 35Ah ultra-low temperature LiFePO4 battery cell (Model P‑90C0n0) is a high-performance lithium iron phosphate cell 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 4000 cycles at 80% depth of discharge, the longest cycle life in PPCELL’s ultra-low temperature series.
With a nominal voltage of 3.2V, 35Ah capacity, and 150Wh/kg gravimetric energy density, the P‑90C0n0 is optimized for energy storage systems operating in sub-zero conditions. The 9.0mm profile and 265Wh/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. Ultra-low internal resistance (≤0.8mΩ) is the lowest in the ultra-low temperature series, minimizing heat generation during high-rate discharge.
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.
