Lithium-ion Capacitors (LICs): A High-Efficiency Solution for Revolutionary Energy Storage

Lithium-ion capacitors (LICs), as a new type of electronic component, differ significantly from traditional capacitors and lithium-ion batteries in their structure and principles. They utilize the movement of lithium ions in an electrolyte to store charge, offering high energy density, long cycle life, and rapid charge and discharge. Compared to traditional capacitors and lithium-ion batteries, LICs not only offer superior energy density but also complete charge and discharge cycles in record time, making them widely considered a breakthrough in future energy storage.

Product Features

LICs possess several exceptional technical features, making them particularly suitable for numerous applications:

1. Excellent Temperature Characteristics: They can be charged at -20°C and discharged at +85°C, extending their operating temperature range from -40°C to +85°C. This ensures stable performance even in extreme conditions, making them suitable for a variety of demanding industrial environments.

2. High Current Capability: They support continuous charging at 20C, discharging at 30C, and instantaneous discharge at 50C. This high current output capability makes it ideal for applications requiring instantaneous high power output.

3. Ultra-low self-discharge: Its capacity is 10 times that of conventional capacitors within the same volume. This means LICs can store more energy in a smaller footprint, significantly improving energy efficiency.

4. High Safety: Made of safe materials, they pose no explosion or fire risk and comply with RoHS and REACH directives. LICs strictly adhere to international environmental and safety standards during production to ensure user safety.

Technical Parameters

The technical parameters of the LIC series products are carefully designed to meet diverse application requirements. The following are examples of typical product parameters:

• Rated voltage: 3.8V to 2.5V, with a maximum charge voltage of 4.2V.

• Capacitance range: Capacitance deviation ranges from -10% to +30% at 20°C.

• Durability: After continuously applying the rated voltage (3.8V) at +85°C for 1000 hours and then returning to 20°C for testing, the capacitance change rate is within ±30% of the initial value, and the ESR (equivalent series resistance) is less than four times the initial standard value.

• High-temperature storage characteristics: After storing at +85°C without load for 1000 hours and then returning to 20°C for testing, the capacitance change rate is within ±30% of the initial value, and the ESR is less than four times the initial standard value.

Practical Applications

LIC's excellent properties make it widely applicable in a variety of fields:

1. Internet of Things (IoT)

In IoT devices, LIC can provide stable energy support for sensors, communication modules, and other low-power devices. Its high energy density and long cycle life enable IoT devices to operate for long periods without frequent battery replacement, significantly reducing maintenance costs.

2. Electronic Toll Collection (ETC) and Dash Cams

In ETC and dash cams, LIC's high current output capability and rapid charge and discharge characteristics ensure reliability when high power output is required. Furthermore, its wide temperature range allows the devices to operate normally in a variety of climates.

3. Automated Guided Vehicles (AGVs)

AGVs require frequent starts and stops and high power output, making LIC's high current capability ideal for these applications. Its long cycle life and low self-discharge characteristics also reduce maintenance frequency and improve production efficiency.

4. Smart Meter Market

In smart meters such as water, gas, and heat meters, LIC can be used in conjunction with a primary lithium battery as a backup power source or peak power compensation power source. Its high safety and environmental characteristics meet the stringent requirements for energy components in smart meters.

5. Communication Auxiliary Power Supplies and GPS Tracking Devices

In communication auxiliary power supplies and GPS tracking devices, LIC's high energy density and rapid charge and discharge capabilities ensure continuous operation in emergency situations. Its wide temperature range also enables the device to maintain stable performance in extreme outdoor environments.

Advantage Comparison

Compared to traditional capacitors and lithium-ion batteries, LIC offers the following significant advantages:

1. High Energy Density: LIC boasts a significantly higher energy density than traditional capacitors, allowing it to store more energy in a smaller volume, resulting in more efficient energy utilization.

2. Fast Charge and Discharge: LIC's charge and discharge speeds far exceed those of lithium-ion batteries and traditional capacitors, meeting the demands of high-speed charging and high-power output.

3. Long Cycle Life: LIC can undergo thousands of charge and discharge cycles without significant performance degradation, significantly extending the device's lifespan and reducing maintenance costs.

4. Environmental Protection and Safety: LIC contains no heavy metals or toxic substances, offering enhanced environmental friendliness and safety, reducing environmental pollution and the risk of battery explosion.

Market Prospects

With the growing global demand for clean energy, LIC, as a highly efficient energy storage solution, holds broad market potential. LIC plays a vital role in electric vehicles, renewable energy storage, mobile electronic devices, and energy storage systems.
