1. The Evolution of Smart City Infrastructure: Why Battery Performance Matters

Smart cities leverage the Internet of Things (IoT), artificial intelligence (AI), and big data to optimize urban operations. From smart meters that monitor energy consumption in real time to GPS trackers that manage logistics fleets, and environmental sensors that detect air quality or water levels, these devices form the "nervous system" of modern cities. However, their effectiveness hinges on one critical factor: uninterrupted power.

Traditional batteries often fall short in smart city environments due to several limitations:

• Short Lifespan: Frequent battery replacements in hard-to-reach locations (e.g., streetlights, underground pipelines) drive up maintenance costs and disrupt service.

• Temperature Sensitivity: Extreme heat or cold—common in urban and industrial settings—can degrade performance or cause failure.

• High Self-Discharge: Batteries that lose charge quickly are impractical for devices requiring long-term standby.

• Safety Risks: In densely populated areas, battery-related hazards (e.g., leakage, overheating) pose significant risks to public safety.

SER Battery’s 3.6V Li-SOCl₂ battery, 3.0V Li-MnO₂ battery, ultra thin battery and ER+SPC solutions are designed to overcome these challenges. By prioritizing longevity, durability, and safety, they enable smart city devices to operate autonomously for years, reducing operational costs and ensuring continuous data collection and service delivery.

2. 3.6V Li-SOCl₂ Battery: The Workhorse of Long-Term Deployments

Lithium-thionyl chloride (Li-SOCl₂) batteries are renowned for their exceptional energy density and long shelf life, making them a staple in low-power, high-reliability applications. SER Battery’s 3.6V Li-SOCl₂ battery builds on this technology, incorporating advanced engineering to meet the rigors of smart city and tracking devices.

• Capacity Range: Available in various capacities (e.g., 2.4Ah to 19Ah) to suit devices from small sensors to high-drain trackers.

• Operating Temperature: -55°C to +85°C, enabling deployment in polar regions, deserts, and industrial environments.

• Self-Discharge Rate: Less than 1% per year at 25°C, ensuring the battery retains over 90% of its capacity after 10 years of storage.

Core Advantages for Smart Cities

• Unmatched Longevity: The 3.6V Li-SOCl₂ battery’s chemistry minimizes internal reactions, allowing it to power devices for 10–20 years in low-drain applications. This is particularly valuable for smart meters (water, gas, electricity) and structural health monitors, which are often installed in inaccessible locations and require decades of reliable operation.

• Extreme Temperature Tolerance: Unlike alkaline or lithium-ion batteries, which struggle in sub-zero or high-heat conditions, SER’s Li-SOCl₂ battery maintains stable voltage output even at -55°C (critical for cold-climate cities like Moscow or Stockholm) and +85°C (ideal for desert regions or industrial zones with high ambient temperatures).

• Low Self-Discharge: For devices that spend most of their lifecycle in standby mode—such as emergency beacons or wildlife trackers—the battery’s minimal self-discharge ensures it remains operational when needed most.

• High Energy Density: Its compact size and lightweight design make it suitable for miniaturized IoT sensors, which are increasingly deployed in smart city infrastructure (e.g., traffic light sensors, waste management monitors).

Real-World Applications
