Coin cell supercapacitors are compact energy storage devices designed to quickly store and release electrical power. Unlike conventional batteries, they offer standout advantages high power density, rapid charging and discharging, and exceptional cycle life.
While their energy density is roughly one-tenth that of rechargeable batteries of the same weight, their power density can be 10 to 100 times higher.
This means supercapacitors can charge and discharge much faster. Plus, they can handle far more charge cycles than traditional batteries, making them ideal for applications that demand high switching loads or frequent bursts of power.
Power Density vs Energy Density
Power density refers to how quickly an energy storage device can release or absorb energy, a key factor for applications that demand short bursts of high power, like starting an engine. Supercapacitors excel here thanks to their high power density, allowing them to deliver energy almost instantly.
Energy density, on the other hand, measures how much energy a device can store over time. A higher energy density is vital for applications that need a steady, long-term power supply.
The new coin cell supercapacitors are versatile and used across a wide range of applications, including backup power supplies, electronic devices, renewable energy systems, and medical equipment. While they’re most commonly used for real-time clock backups, they also serve well in memory backup, battery swap ride-through, and LED or audible alarm circuits.
They’re suitable for systems operating at up to 5.5 V, with capacitance values ranging from 100 to 1,500 mF.
Key Features:
- Very compact design
- High power density
- Low leakage current
- Long lifetime
