Ultra-Low Temperature Power Solution for Polar Scientific Research & Oil-Gas Exploration Equipment
Ⅰ. Core Industry Pain Points
Field unattended equipment deployed in polar scientific research stations, frigid oil and gas fields in Northeast China and Siberia, as well as high-altitude permafrost regions, operates continuously under extreme temperatures below -40℃. Traditional power supply solutions face three major technical bottlenecks:
Severe performance failure of conventional batteries at ultra-low temperatures：Commercial lithium batteries lose over 50% of their capacity at -20℃ and suffer sharp internal resistance surge at -40℃, leading to failed discharge. Lead-acid batteries exhibit even worse low-temperature attenuation. Their bulky and heavy structure also makes them incompatible with miniaturized field terminals.
Insufficient discharge rate of traditional primary batteries：Although lithium thionyl chloride and lithium manganese primary batteries deliver basic low-temperature resistance, they only support low-current output. They cannot meet the instantaneous high-current demands of intelligent terminals equipped with wireless communication and data acquisition functions.
Exorbitant on-site operation and maintenance costs：Frigid and remote regions are difficult to access for manual inspection. Frequent battery replacement caused by short service life greatly increases full-lifecycle project costs and disrupts the continuity of field monitoring data.
Ⅱ. Core Technical Advantages
Developed based on our proprietary wide-temperature battery technology platform, this solution is specially optimized for extreme cold operating conditions and fundamentally solves low-temperature power supply challenges through material innovation:
Adopting a special low-temperature electrolyte system and nano-modified anode technology, our cells effectively reduce electrochemical polarization and improve lithium-ion conduction efficiency at ultra-low temperatures.；
The low-internal-resistance electrode design maintains a stable voltage platform during high-current discharge, preventing terminal restart caused by sudden voltage drop.；
Fully sealed housing and wide-temperature structural design enable reliable operation under complex field conditions with drastic temperature differences, high altitude and intense vibration.。
Core Performance Specifications：Capacity retention: ≥90% @ -50℃, ≥80% @ -80℃; Annual self-discharge rate: ≤2%; Supports long-term unattended operation of field equipment in extreme cold environments.
Ⅲ. Solution Value
All-climate reliable power supply：Covers an ultra-wide operating temperature range of -80℃ ~ +60℃, adapting to drastic diurnal and seasonal temperature changes. It ensures uninterrupted data collection of monitoring equipment throughout the year.
Substantially reduced O&M costs：Ultra-low self-discharge rate and high-capacity design support 3–5 years of maintenance-free operation. It reduces on-site inspection frequency in frigid remote areas and cuts overall project lifecycle costs.。
Strong compatibility with diverse terminals：Supports wide-range rate discharge from milliampere-level low-power sensors to ampere-level communication terminals. Custom battery packs with flexible series-parallel configurations are compatible with mainstream interfaces of various field monitoring equipment.
