With the explosive growth of new energy vehicles, energy storage devices and various electronic products, batteries have become a critical carrier supporting modern life. However, accidents such as fires, explosions and leakages during battery storage occur from time to time, causing not only huge property losses but also serious threats to personal safety and the environment. Safe battery storage is by no means a simple matter of "finding a place to put them", but a systematic project covering fire and explosion protection, short circuit prevention, temperature control, leakage collection and waste gas treatment.

How to strike a balance between efficient turnover and absolute safety? The intelligent battery storage cabinets launched by DeSUN ECOTECH provide a professional answer with intelligent, digital full-scenario safety solutions.

Fire and Explosion Protection: Locking Risks Through Structural Design

The top priority for safe battery storage is to address combustion and explosion caused by thermal runaway. Whether for finished batteries, waste batteries or batteries under test, internal short circuits or thermal shocks will generate instant high temperatures and flammable gases that can easily trigger explosions. This requires storage equipment to have intrinsic explosion-proof safety capabilities.

DeSUN ECOTECH intelligent battery storage cabinets strictly comply with relevant standards such as Management Specification for Recycling of Traction Batteries for Vehicles – Part 2: Recycling Service Outlets (GB/T 38698.2-2023). The cabinet body is made of high-strength explosion-proof steel with a three-layer fireproof structure, achieving a full-cabinet explosion-proof rating. More importantly, the cabinets are equipped with pressure relief explosion-proof valves or dedicated pressure relief devices. When the internal pressure rises abnormally, they can release energy directionally, effectively resisting explosion impact, containing accidents inside the cabinet and buying time for external rescue. This combined design of containment and diversion minimizes the hazards of thermal runaway from the root.

Short Circuit Protection: Insulation and Isolation to Eliminate Ignition Sources

External short circuits, accidental contact between positive and negative electrodes, and moisture-induced creepage are easily overlooked fire causes in battery storage. An inconspicuous metal tool or a pool of condensation water can cause short-circuit sparks and directly ignite batteries. Therefore, preventing accidental contact and leakage circuits is a mandatory requirement for safe storage.

DeSUN ECOTECH cabinets are built with high-quality insulation layers, realizing reliable electrical isolation from cabinet partitions to supporting structures, completely avoiding accidental contact between battery electrodes and preventing short-circuit fires. Meanwhile, the design fully takes static electricity dissipation and moisture-proof sealing into account, further eliminating potential ignition sources and ensuring batteries remain safe and controllable in all positions inside the cabinet.

Constant Temperature Control: Keeping Batteries in a Stable, Safe State

Temperature is a barometer of battery lifespan and safety. Excessively high ambient temperature accelerates electrolyte decomposition, increases internal pressure and triggers thermal runaway; excessively low temperature easily causes lithium plating and leaves hidden safety risks. In storage, batteries of different systems have different temperature requirements. For some traction batteries, the recommended storage range is 5℃ to 35℃, while harsh working conditions may require wider temperature management capabilities.

To meet this challenge, DeSUN ECOTECH intelligent battery storage cabinets are equipped with an intelligent temperature control module that can be accurately adjusted within the range of -10℃ to 60℃, adapting to diverse storage needs from low-temperature lithium batteries to high-temperature-resistant batteries. The constant temperature control system operates automatically around the clock, acting like a "safety climate chamber" that protects batteries from extreme heat and cold, significantly reducing safety risks caused by improper thermal management.

Leakage Prevention and Waste Gas Purification: Balancing Environmental Protection and Safety

Electrolyte leakage is another intractable problem in battery storage. Once leaked, fluorine-containing electrolyte will not only corrode equipment but also generate toxic and harmful gases such as hydrogen fluoride, seriously polluting the environment and endangering human health. Traditional storage methods have almost no countermeasures for this, making many outlets dread electrolyte leakage.

DeSUN ECOTECH intelligent battery storage cabinets provide an environmentally compliant solution with a dual defense line of "leakage prevention + gas purification". The bottom of the cabinet is equipped with anti-leakage trays that can effectively contain leaked electrolyte and prevent liquid overflow and soil contamination. Meanwhile, the built-in waste gas purification facility adopts chemical neutralization materials for targeted treatment of harmful components such as fluorides generated from anode material leakage and thermal runaway, followed by high-efficiency filtration to ensure waste gas inside the cabinet meets emission standards. This design not only guarantees storage safety but also fulfills environmental responsibility.

For this reason, DeSUN ECOTECH’s "intelligent and digital retired battery storage equipment" was successfully selected into the 2025 Catalogue of Practical Technologies and Typical Projects for Ecological Environmental Protection, gaining national-level recognition and marking that its technical route and environmental value are at the forefront of the industry.

Zoned Isolation and Intelligent Management: Refined Control for Improved Efficiency and Safety

Chaotic storage accelerates accidents. Mixing batteries of different types, states of charge and aging degrees can easily trigger chain reactions due to state differences. Safe storage must achieve refined zoned isolation and prohibit unsorted mixed storage.

DeSUN ECOTECH intelligent battery storage cabinets support classified storage of batteries of different specifications and states, realizing physical isolation through independent compartments and labeling systems for daily management and emergency disposal. On this basis, the cabinets further integrate digital intelligent management, with expandable auxiliary modules such as charge-discharge functions. They monitor key parameters such as internal temperature, gas concentration and battery status in real time, and trigger immediate alarms for abnormal conditions.

Whether for on-site turnover in battery manufacturing plants, temporary storage of retired batteries in new energy battery recycling institutions, precision testing in laboratory areas, or spare parts management in new energy equipment operation and maintenance centers, DeSUN ECOTECH cabinets provide safe, environmentally friendly and intelligent one-stop support for temporary storage and circulation of batteries with their full-scenario adaptability.

There is no room for luck in battery safety, only foolproof solutions. From the robust structure for fire and explosion protection, to multi-layer safeguards against short circuits, temperature fluctuations, leakages and polluted emissions, to intelligent zoned management, DeSUN ECOTECH intelligent battery storage cabinets redefine the standards for safe battery storage. With both safety and environmental protection in place, and digital technology integrated into physical protection, battery storage is no longer a source of sleepless anxiety, but a manageable, controllable and reliable intelligent node. Entrusting professional matters to professional equipment is the most reliable safety approach in this new energy era.
