Engineered for high thermal tolerance, longevity, and intelligent management across severe applications.
Vietnam is experiencing a rapid industrial transformation. While known for its tropical climate, certain geographical and vertical markets demand highly specialized battery solutions. In the mountainous northern regions such as Lào Cai (Sa Pa), Lạng Sơn (Mẫu Sơn), and Hà Giang, winter temperatures can fall below 0°C. Heavy telecommunication towers, border monitoring systems, and local rural microgrids require battery packs capable of constant, stable discharge without suffering from sub-zero thermal collapse.
More critically, Vietnam’s agricultural export surge has catalyzed the development of massive cold chain logistics networks in Binh Duong, Long An, and near Hai Phong Port. The indoor environments of these modern blast freezers operate constantly between -18°C and -30°C. Conventional lithium-ion packs experience catastrophic chemical deceleration at these levels, reducing active service time by up to 60%. As a premier low-temperature lithium battery manufacturer, Guangdong Nuwon Energy Co., Ltd. fills this technical gap with specialized electrolyte compositions and integrated thermal management.
Maintaining a stable 80% discharge capacity down to -30°C for automated guided vehicles in cold warehouses.
Reliable backup power supplies in northern border regions during prolonged winter frost periods.
At temperatures below 0°C, typical lithium-ion batteries fail due to two main physical-chemical changes: the sharp increase in electrolyte viscosity (which halts lithium-ion transportation) and the high charge transfer resistance at the anode-electrolyte interface. This induces dangerous lithium plating on the anode, resulting in accelerated capacity loss or short-circuit failures.
To overcome this, Guangdong Nuwon Energy utilizes a multi-solvent low-freezing electrolyte formula. By incorporating low-viscosity carboxylic acid esters (such as methyl acetate or ethyl propionate) and engineered lithium salts like LiFSI (Lithium bis(fluorosulfonyl)imide), our low-temperature cells retain fluid dynamics at -40°C. Coupled with nano-structured silicon-carbon anodes that feature optimized tortuosity, lithium ions intercalate swiftly even during rapid discharge under sub-zero parameters.

Clear, direct technical answers addressing design requirements for low-temperature lithium battery deployment.
Typical lithium-ion chemistries rely on liquid electrolytes. When temperatures drop below 0°C, the viscosity of these liquid solvents increases, which restricts lithium-ion mobility. This deceleration causes a rapid voltage drop (sag), triggering early low-voltage cutoff warnings on machinery. Additionally, fast charging in these conditions causes lithium metal plating on the anode, which degrades cycle life and poses a safety risk of internal short circuits.
By utilizing a proprietary electrolyte formulation and specialized anode designs, our low-temperature cells (such as our 21700 RS50 and custom LiFePO4 cells) retain over 80% of their rated capacity at -30°C under moderate discharge rates. Standard lithium-ion batteries typically retain less than 40% capacity in similar conditions.
For low-temperature battery packs, our smart BMS monitors the ambient and internal temperature of the cells. When the system detects temperatures below 0°C and a charge command is received, the BMS routes power to integrated thin-film polyimide heating elements located between the cells. Once the temperature reaches a safe operating range (typically 5°C to 10°C), the BMS shuts off the heater and starts the charging process, preventing damage to the cells.
For urgent orders, overland shipping via our logistics networks takes 3-5 days from our factory in Guangdong to locations around Hanoi. For larger volume orders, maritime freight shipping from Guangzhou or Shenzhen ports to Hai Phong or Ho Chi Minh City (Cat Lai) takes approximately 5-7 days.
