Select high-performance energy units configured specifically to resist electrolyte depletion and internal resistance spikes in high ambient heat.
Hai Phong, Northern Vietnam’s primary logistics hub and manufacturing powerhouse, experiences rapid industrial growth across economic corridors like the Dinh Vu-Cat Hai Economic Zone. However, the region's harsh tropical climate presents major obstacles for industrial operators. High average relative humidity of 85% paired with summer temperatures exceeding 38°C (and rising above 50°C in unventilated industrial settings or enclosed control rooms) accelerates standard electrochemical battery degradation.
High ambient heat combined with coastal salinity creates a corrosive environment that compromises standard battery enclosures and degrades electrode materials. When standard lithium-ion or lead-acid cells operate in these conditions, they face rapid capacity loss, safety hazards, and thermal runaway. To address these challenges, heavy machinery, automated port logistics, off-grid telecommunications, and manufacturing sites require batteries designed with high thermal thresholds and robust environmental protection.
Comparing battery performance lifetimes at elevated temperatures.
At high temperatures, standard batteries undergo accelerated side reactions that shorten their lifespan. For instance, standard lithium-ion batteries using LiPF6 in organic carbonate solvents experience electrolyte decomposition above 45°C. This degradation thickens the Solid Electrolyte Interphase (SEI) layer, consuming active lithium ions and increasing internal resistance.
Our high-temperature resistant batteries solve this problem by incorporating thermal stabilizers in the electrolyte, using heat-resistant separators, and using Lithium Iron Phosphate (LiFePO4 / LFP) chemistry. The strong covalent phosphorus-oxygen bonds in the LFP crystal structure are inherently stable at high temperatures, preventing oxygen release and thermal runaway even up to 60°C. For industrial environments, these cells utilize high-temperature binders (such as specialized PTFE and PVDF grades) to maintain electrode integrity through deep charge/discharge cycles in hot weather.
"Standard lead-acid and lithium chemistries degrade exponentially for every 10°C increase above 25°C. Our LFP formulations maintain a high cycle life even at prolonged operating temperatures of 45°C, ensuring reliable industrial performance."
We provide specialized, high-discharge lithium packs and high-temp electrode binders for localized factory manufacturing and demanding logistics systems.

Our factories in Ningbo are strategically located near the Ningbo-Zhoushan Port. This proximity offers significant cost and speed advantages for importing industrial battery systems into Northern Vietnam. The ocean shipping lane from Ningbo to Hai Phong Port is a highly efficient trade corridor, with transit times typically ranging from just 5 to 7 days. This quick turnaround minimizes supply chain delays for large-scale energy projects in Vietnam.
To support buyers in Hai Phong's industrial zones, we provide complete export documentation, including UN38.3 test reports for dangerous goods, MSDS, and Form E Certificates of Origin. Under the China-ASEAN Free Trade Agreement, the Form E certificate allows importers to access preferential custom tariffs, significantly reducing the total cost of ownership (TCO) for these battery systems.
Our engineering team works closely with local EPC contractors and system integrators in Hai Phong, providing remote commissioning assistance, customized CAD layout drawings, and detailed thermal modeling to ensure long-term system stability in humid coastal environments.
High-temperature resistant batteries are vital across several sectors in Hai Phong. In port operations, they power Automated Guided Vehicles (AGVs) and heavy container handling equipment that run 24/7 in direct sunlight. Standard batteries in these environments often overheat and shut down due to thermal limits, but our high-temperature LFP cells operate continuously without risk of thermal runaway.
In manufacturing sites, like the electronics assembly plants in VSIP Hai Phong and the automotive facilities in Cat Hai, our high-temp batteries provide uninterrupted power supply (UPS) and load-shifting energy storage (ESS). These systems protect production lines from grid fluctuations while enduring high ambient temperatures near machinery. Additionally, our batteries are designed to resist high humidity and salt mist, making them ideal for telecom base stations, off-grid coastal navigation aids, and modern fishing vessels operating in the Gulf of Tonkin.
Our production facilities maintain strict compliance with international standards. We perform automated cell matching to verify internal resistance consistency, execute rigorous temperature chamber cycling, and conduct mechanical vibration tests to ensure every battery pack meets the demands of heavy industrial use.
