SUNJ Energy's Battery Capacitors offer the perfect blend of high energy storage and rapid pulse discharge. Designed for peak performance in smart metering, GPS tracking, IoT, and security applications, they combine the strengths of lithium batteries and supercapacitors.

Key Features
● High Pulse Current Output – Instantly delivers high current for communication bursts
● Low Self-Discharge – Less than 2% per year, ensuring long shelf life
● No Passivation Delay – Eliminates voltage delay typical in bobbin-type Li-SOCl₂ batteries
● Wide Operating Temperature – Stable from -40°C to +85°C, suitable for extreme environments
● Compact & Lightweight – Space-saving design with high sealing performance
● Safe & Reliable – Built-in safety valve, anti-explosion structure, RoHS compliant

Structural Advantages
These hybrid capacitors are commonly paired with Li-SOCl₂ batteries to improve output efficiency and handle high-current pulses, making them ideal for both continuous background power and burst energy demands. Internally, they adopt a double-layer electrochemical structure with activated carbon and organic electrolyte, enabling ultra-low ESR and high discharge rates.

Typical Applications
● ETC and smart traffic systems
● AMR & AMI utility meters
● Smart locks, smart homes, and fire alarms
● GPS and GSM tracking devices
● RFID and remote sensors
● Shared bikes and smart parking systems
● Solar or energy harvesting devices
● Military and marine equipment (e.g., sonar buoys)

Available Configurations
● Standard EPC models (e.g., EPC1520, EPC1530, EPC1550)
● Voltage range: 2.5V–4.0V (charging cutoff voltage ≤4.1V)
● Compatible with cylindrical or custom battery packs
● Connector and housing customization available

Custom Integration Services
In addition to Battery Capacitors, SUNJ Energy offers a full range of lithium primary batteries, including Li-SOCl₂ and Li-MnO₂, as well as tailored battery pack assemblies. Our technical team works closely with clients to deliver safe, efficient, and application-specific power solutions.

▎Note: Avoid over-discharging below 2.0V or exposing to heat above 100°C. Do not burn, short-circuit, or immerse in water. Store in a dry, cool environment below 30°C.
