Lithium-ion battery end-to-end safety solution

Lithium-ion batteries are clean and efficient renewable energy sources, but if damaged, they can release a sudden surge of current, posing safety hazards such as fires and explosions. ZOYET solves the safety challenges of lithium-ion battery storage!

The safety hazards of lithium batteries stem from the multiple complexities of their inherent properties:

High-risk composition: The core electrodes consist of metals such as cobalt, lithium, and nickel, and the internal electrolyte contains flammable and explosive components, acting like a hidden "spark of energy."

Extremely difficult to degrade naturally: In the natural environment, lithium batteries have a decomposition cycle of up to decades, making them veritable "stubborn waste."

Hidden pollution risks: Once internal chemical substances leak, they can seep into the soil and water sources, becoming "invisible environmental killers."

Seemingly small lithium batteries pose risks across three major dimensions: physical, chemical, and environmental, making them a veritable "all-encompassing source of danger":

* Physical Impact: A broken casing instantly releases a strong current, easily igniting an open flame or even exploding—the destructive power should not be underestimated.

* Chemical Harm: Electrolyte leakage can directly corrode skin and mucous membranes, while releasing toxic gases such as hydrogen fluoride, harming human health.

* Ecological Impact: Heavy metals slowly seep into soil and groundwater, disrupting the ecological balance and potentially impacting humans through the food chain.

Lithium batteries possess the dual attributes of "solid waste" and "hazardous chemicals," and their storage and disposal must adhere to professional safety regulations!

So how do we store lithium batteries safely?

01 Explosion-proof certification:

International standards ensure a solid safety baseline. Storage devices must pass the EU ATEX or the national-level explosion-proof certification EXNEPSI to ensure that they can maintain structural stability and withstand risk impacts even in extreme scenarios.

02 Triple Protection System:

• Intelligent Fire Extinguishing System: Equipped with an automatic dry powder or gas fire extinguishing device, it responds to fires in milliseconds, quickly extinguishing the fire source and preventing its spread.

• 24/7 Monitoring and Alarm System: Integrates temperature, smoke, and gas leak detection modules, providing 24/7 continuous patrol and immediate warnings for abnormal situations.

• Zoned Isolation Design: Utilizes independent explosion-proof cabinets for partitioned storage, preventing a single battery failure from triggering a chain reaction and eliminating the risk of "one point of danger igniting the whole."

03 Environmental Management:

• Anti-static Protection: Professional conductive materials are laid inside the cabinet, and operators wear anti-static equipment to avoid the risk of static electricity ignition at the source.

• Leakage Prevention Design: Equipped with secondary sealed containers and leak-proof trays, providing double protection to prevent electrolyte leakage and avoid environmental pollution.

• Temperature, Humidity, and Lightning Protection Management: Humidity monitoring devices and lightning rods are installed to precisely control the storage environment and eliminate safety hazards caused by high temperatures, humidity, and lightning strikes.

At the same time, warning signs are posted in prominent locations in the storage facilities to clearly define safety restricted areas and strengthen the risk awareness of all employees!

Based on in-depth research into the safety characteristics of new energy batteries, ZOYET has independently developed a series of safety management products to provide systematic safety protection for the entire battery life cycle, covering core scenarios such as storage, transportation, and charging.

01 Battery Safety Storage Box:

As a core innovative product of ZOYET, it is specifically designed to address the risk of thermal runaway in new energy batteries. It integrates storage, transfer, and emergency handling functions, providing dual safety protection for battery production, assembly, transportation, and recycling.

Battery Safety Storage Box

• The enclosure is constructed from 5mm high-quality carbon steel, with fire-resistant and heat-insulating materials sandwiched between layers, providing excellent structural strength and fire and heat resistance.

• A professional pressure relief vent is located at the top, allowing for rapid release of high-pressure gases generated by battery combustion, preventing secondary risks from enclosure explosion.

• Fire-resistant sealing strips are installed at the door seams, ensuring both airtightness and fire resistance, effectively preventing the leakage of flames and toxic gases.

• A water inlet is provided at the top for connecting to an external water source to cool the batteries, and a manual drain valve is designed at the bottom for easy recovery and disposal of corrosive liquids.

• Equipped with a level gauge and a high-temperature range temperature display (0~800℃), it monitors the internal status of the enclosure in real time, accurately controlling safety risks.

• Nitrogen springs are installed on both sides to assist in opening the cabinet door, making operation convenient and effortless.

• The bottom is equipped with heavy-duty load-bearing swivel casters (each with a load capacity of 1000kg), combined with a forklift slot design, meeting flexible transportation needs in various scenarios.

In emergency scenarios, when a battery experiences heat release or thermal runaway during testing, repair, assembly, or production, the equipment's pressure relief system and cooling system can respond quickly and effectively suppress the spread of hazards such as deflagration, leakage, and corrosion.

In storage and transportation scenarios, its high-strength structure and sealed design ensure the safety and stability of the battery during transportation and temporary storage.
