The “Retirement Wave” of Energy Storage Power Stations and Hidden Safety Crises
With the booming development of the electrochemical energy storage industry, the first batch of operational energy storage power stations are experiencing a “retirement wave” of power batteries. These retired batteries are often referred to as “urban mines,” but if not handled properly, they are potential “safety bombs.” The residual charge inside the battery is the root of its danger. During disassembly, transportation, or storage, if thermal runaway is triggered by collision, compression, or short circuit, it can easily lead to spontaneous combustion or even explosion. How to safely and efficiently handle this large-scale retired battery has become a serious challenge that the entire industry urgently needs to address.
The Core Challenges of Retired Power Battery Disposal
The disposal of retired batteries is not a simple physical disassembly. Its core challenges lie in:
- The unpredictability of residual energy: Inconsistent internal resistance and different states of charge (SOC) of batteries result in extremely unstable residual charge and voltage, creating significant safety hazards for subsequent processing.
- The contradiction between safety and efficiency in large-scale batch processing: Traditional discharge methods (such as resistance discharge) are inefficient, generate significant heat, and cannot completely eliminate the chemical activity inside the battery, multiplying the risks during batch processing.
- The harsh requirements of complex industrial environments: Processing sites may face electrolyte leaks, corrosive substances, and potential explosion risks. Ordinary equipment struggles to operate stably and safely in such harsh environments.
Guheng Energy’s Mobile Power Battery Immersion Tank Solution
To address these challenges, as a provider of new energy service technology solutions, Guheng Energy has launched an innovative mobile power battery immersion tank, aiming to mitigate the safety risks of retired batteries at the source.
Working Principle: Achieving ultimate battery deactivation through “immersion discharge”
The core of this solution is to immerse the retired battery entirely in a specially formulated conductive solution. Through a gentle and uniform electrochemical reaction, the residual charge inside the battery is completely and slowly released, ultimately reducing its voltage to an absolutely safe 0V range. This process is called “deactivation,” meaning the battery permanently loses its electrochemical activity, fundamentally eliminating the risks of spontaneous combustion and explosion.
“Mobile” Design: Revolutionary Advantages of Flexibility
Unlike stationary processing equipment, the highlight of Guheng Energy’s mobile power battery immersion tank lies in its “mobility.” It can be directly deployed at energy storage power station sites, battery recycling centers, or anywhere else needed, achieving flexible operation “wherever needed, it goes.” This not only eliminates the high costs and risks of long-distance transportation of hazardous batteries but also enables rapid response, making it an indispensable safety guardian for sudden batch battery disposal or emergency handling.
Superior Product Performance, Ensuring Ultimate Safety
We deeply understand that equipment for handling high-risk batteries must itself be a safety benchmark. Therefore, Guheng Energy’s immersion tanks adhere to the highest standards in design and manufacturing:
- IP65 Protection Rating: Ensures all-around protection against dust intrusion and low-pressure water spray from any angle, guaranteeing stable operation of the internal electrical system in humid and dusty industrial environments.
- 0.5MPa Explosion-proof Design: The tank and key components possess extremely high explosion-proof pressure resistance, effectively controlling the impact of an accidental battery explosion within the equipment, acting as a robust “safety fortress” to protect on-site personnel and equipment.
- Excellent Corrosion Resistance and Robustness: The main body of the equipment is constructed of 304 stainless steel or a “PP water tank + stainless steel frame” structure, with professional welding ensuring no leakage and no oxidation. The inner lining is made of fiberglass grating, effectively mitigating the impact during battery placement and increasing load-bearing capacity, ensuring durability.
To meet the needs of different customers, we offer various models, such as the STB-200 immersion tank (internal dimensions 2.1*2.6*0.4m) suitable for large-scale batch processing and the STB-50 immersion tank (internal dimensions 0.8*1.6*0.4m) suitable for laboratory or small-scale processing. All products come standard with multiple safety accessories, including pressure relief valves, safety valves, and explosion-proof mesh, ensuring safety in every detail.

Conclusion: The Cornerstone of a Green Energy Closed Loop
Safety is the lifeline for the sustainable development of the energy storage industry. At Guheng Energy, we firmly believe that the safe handling of retired batteries is the cornerstone of building a closed loop for the entire life cycle of green energy. Our mobile power battery immersion tanks are a key product based on this concept. It is not just equipment, but a reliable safety commitment.
In addition to immersion tanks, we can also provide complete battery maintenance and testing solutions. For example, in the daily operation of energy storage power stations, Guheng Energy’s portable battery pack equalization and maintenance instrument PBM series can effectively screen for potential risks in battery packs; while the portable airtightness leak detector QMM series can strictly control the safety of newly manufactured batteries. Guheng Energy is committed to becoming your most trusted partner in the entire lifecycle of battery management.
FAQ
Q: Can batteries treated in the mobile power battery immersion tank be directly discarded as ordinary waste?
A: No. The core function of the immersion tank is to perform “discharge” and “deactivation” treatment to completely eliminate the electrochemical risks of the battery. However, the heavy metals and chemicals contained in the battery itself still exist, classifying it as hazardous solid waste. The treated safe batteries must be handed over to qualified battery recycling companies for subsequent resource recovery and harmless treatment.
Q: Can Guheng Energy’s immersion tank handle all types and specifications of power batteries?
A: We offer various specifications such as STB-200 and STB-50, covering common forms of retired power batteries from modules to standard battery packs. For special specifications or extra-large sizes, we support product customization. Please contact our technical engineers for customized solutions.
Q: Will immersion discharge produce toxic or flammable gases?
A: Guheng Energy’s immersion tank uses a specially formulated environmentally friendly conductive solution designed to achieve a mild and controllable electrochemical reaction. Under normal operating conditions, the process does not produce flammable or explosive gases such as hydrogen, or toxic or harmful gases, ensuring operational safety and environmental friendliness.
Q: What are the advantages of immersion discharge compared to traditional physical discharge methods?
A: Traditional physical discharge (such as resistance discharge) is inefficient, generates significant heat, and cannot completely eliminate the battery’s “open circuit voltage” and internal chemical activity. Immersion discharge achieves uniform and thorough discharge, reducing the voltage to 0V, achieving intrinsic safety. Simultaneously, it enables automated batch processing, resulting in higher efficiency and lower overall costs.
Q: Is the equipment maintenance complex?
A: The equipment is robustly designed and durable, requiring minimal daily maintenance. The specially formulated solution has a long lifespan; the specific replacement cycle depends on the throughput. Our equipment is equipped with an intelligent monitoring system and provides comprehensive after-sales technical support and maintenance guidance, ensuring your peace of mind.
