One . Background

Lithium batteries are now widely used in a variety of electronic and electromechanical products, including smartphones, automobiles, and energy storage systems. However, the inherent instability and flammability of lithium batteries pose significant risks throughout their production, storage, transportation, and use. Currently, the industry lacks any effective solutions for early fire detection in lithium‑battery applications. In response to these challenges, our company has developed a lithium‑battery fire‑prevention and early‑warning system.

This system can be deployed across various stages of lithium‑battery production, storage, and logistics, including battery‑cell manufacturing workshops, finished‑goods warehouses, semi‑finished‑goods warehouses, racking systems, and transportation processes.

Two . Function Implementation

 2.1 Principle

Before a single lithium battery catches fire, its temperature rises and it emits an unusual odor, producing a light haze that settles and drifts outward—haze that smoke detectors cannot sense. As the smoke grows denser, the battery eventually ignites and explodes. In response to these scenarios, appropriate sensors should be selected to detect lithium‑battery anomalies; once a sensor detects an abnormality, it will… Wireless transmission , report to the relevant manager, who will then take appropriate action.

During the process in which a single lithium battery heats up to the point of ignition, it will emit an unpleasant odor and produce a small amount of smoke. This module monitors the air for… P M2.5/PM10,TVOC,CO An air quality sensor. When P M2.5/PM10,TVOCS ， C Oh, An alarm is triggered when the temperature rises abnormally.

2.2 System Implementation

Our company has developed a fire‑warning system for lithium batteries; this system… by It consists of three components: the sensor, the transmission unit, and the alarm platform.

The sensor employs a gas sensor and an infrared matrix temperature‑sensing sensor; the gas sensor detects by measuring… P M2.5/PM10,TVOCS ,CO2 Wait until it becomes point An abnormal temperature rise is used to determine whether the lithium battery has begun to fail, while an infrared array temperature‑sensing sensor detects surface temperature changes on the lithium battery to assess its degradation.

In this system, the transmission unit employs a hybrid wired-and-wireless approach: infrared temperature sensors generate large data volumes and are transmitted via Ethernet, while lithium‑battery failure detection sensors produce relatively small data sets and support wireless communication.

Four . Scenario Applications

4.1 Lithium Battery Production Workshop

During lithium‑battery manufacturing, numerous uncertainties can lead to thermal runaway and fires; therefore, it is essential to monitor the battery’s temperature rise and particulate emissions throughout the production process. When either of these parameters deviates from its set threshold, the alarm system is immediately activated.

Our company’s lithium‑battery failure detector can be used to monitor the entire workshop.

 

4.2 Lithium Battery Finished-Product Storage Warehouse

  The finished‑goods warehouse for lithium batteries is stocked with completed units, all of which are fully packaged. These batteries cannot be monitored for surface temperature; instead, their condition is assessed based on particulate matter and odor. Particulate‑matter and odor sensors have been installed in the finished‑goods warehouse, and when abnormal levels of particulates or unusual odors are detected, an alarm is triggered immediately.

Our company’s lithium‑battery failure detector can be used to monitor the entire workshop.

 

 

4.3 Energy Storage Batteries

    It is integrated with the energy storage battery and triggers an alarm when it detects a sudden increase in temperature, particulate matter, or unusual odors within the battery.

    Our company’s lithium‑battery failure detector and infrared thermal‑array temperature sensor can be used to monitor the entire energy‑storage battery cabinet.

 

 

4.4 Power Battery Rack

     Power battery racking is a warehousing system specifically designed for the storage and management of power batteries—such as lithium-ion batteries and lithium iron phosphate batteries. In addition to basic storage functions, it incorporates a range of intelligent and safety‑enhanced features to meet the stringent requirements of the new‑energy industry for battery storage.

Power battery racks pose multiple safety hazards during storage, handling, and charging/discharging, potentially leading to serious incidents such as fires, explosions, and toxic gas leaks.

  Our company’s lithium‑battery failure detector and infrared thermal‑array temperature sensor can be used to monitor the surface temperature of power batteries.

 

 

 

4.4 Lithium Battery High-Temperature Storage Workshop

The high-temperature aging workshop for lithium batteries is a critical stage in the production or testing process. It is primarily used to conduct stability tests, aging screening, or performance evaluations under elevated temperatures, ensuring the safety and consistency of the batteries. By accelerating internal chemical reactions at high temperatures, this process helps identify batteries with potential defects, such as electrolyte decomposition, SEI film instability, etc.). Early‑failure batteries are screened out to enhance the reliability of shipped products. Conventional storage: 45°C–60°C (for standard aging tests). Extreme testing: 60°C–85°C (requires strict monitoring to prevent thermal runaway).

 

In such extremely high-temperature environments, most fire detectors cannot operate reliably over the long term. Our company has developed a lithium‑battery failure detector specifically for high‑temperature storage workshops, designed to monitor whether lithium batteries in these facilities have failed and to proactively prevent fires caused by battery malfunctions.

 

The rapid growth of the lithium‑battery industry has posed unprecedented challenges to safety management and risk prevention. I The company has launched a full‑chain lithium‑battery fire‑early‑warning system that, leveraging innovative multi‑parameter fusion sensing technology, a robust IoT architecture, and custom‑designed equipment for extreme environments, accurately detects early signs of thermal runaway, thereby successfully addressing a critical gap in the industry’s capabilities for lithium‑battery fire prevention. Early warning A gap in the field. This system not only establishes a robust safety barrier across the entire lifecycle of lithium batteries—covering production, warehousing, transportation, and end-use applications such as energy storage and power‑train batteries—effectively mitigating major fire risks and safeguarding both human life and property; it also helps the entire new‑energy industry chain achieve safer, more sustainable, high‑quality development.
