The application characteristics of lithium battery packs in emergency lighting equipment are mainly reflected in the following aspects:

High energy density and long battery life

Lithium battery packs feature high energy density and can store more electrical energy within a limited volume, providing long-lasting power for emergency lighting equipment. Compared with traditional lead-acid batteries, lithium battery packs are smaller in size, lighter in weight, and have a longer battery life, meeting the needs of long-term emergency lighting. For instance, in emergency situations such as fires and earthquakes, lithium battery packs can support emergency lights to operate continuously for several hours or even longer, buying crucial time for personnel evacuation and rescue.

2. Fast charging and discharging and efficient response

The lithium battery pack supports fast charging and can complete power replenishment in a short time, reducing the standby time of the device. Meanwhile, it has a high discharge efficiency and can quickly respond to emergency lighting demands, immediately activating the lighting function at the moment of power failure. This efficient response capability is crucial for emergency scenarios, ensuring that personnel receive lighting support immediately in the first instance of an emergency.

3. Long service life and low maintenance cost

Lithium battery packs have a long cycle life, usually reaching thousands of charge and discharge cycles, which is much longer than that of traditional batteries. This means that throughout the entire life cycle of emergency lighting equipment, lithium battery packs do not need to be replaced frequently, reducing maintenance costs and human input. In addition, the self-discharge rate of lithium battery packs is low, and they can maintain a high level of power even after long-term storage, further enhancing the reliability of the equipment.

4. Wide temperature range adaptability and stability

Lithium battery packs can maintain stable performance even in extreme temperature environments, with an adaptability range typically from -20℃ to 60℃. This wide temperature range adaptability enables it to provide reliable power support for emergency lighting equipment even under harsh conditions such as high and low temperatures, ensuring the normal operation of the equipment in various extreme environments.

5. Lightweight and portability

The lithium battery pack is small in size and light in weight, significantly reducing the overall weight of the emergency lighting equipment and enhancing its portability. This feature is particularly important in emergency scenarios that require rapid deployment or movement, such as outdoor rescue and temporary shelters, making it convenient for personnel to carry and install.

6. Intelligent Management and Security

Lithium battery packs are usually equipped with advanced battery management systems (BMS), which can monitor the battery status in real time and prevent safety hazards such as overcharging, overdischarging and short circuits. Meanwhile, lithium battery packs have high safety. For instance, lithium iron phosphate batteries have a high thermal runaway temperature and are not prone to explosion and combustion, further reducing the risk of using emergency lighting equipment.

7. Environmental Protection and Sustainability

Lithium battery packs do not contain heavy metals such as lead and mercury, causing no pollution to the environment and meeting modern environmental protection requirements. In addition, lithium battery packs can be recycled, reducing resource waste and conforming to the concept of sustainable development.
