LIC Type Supercapacitor

Lithium ion supercapacitor (LIC) is a hybrid electrochemical energy storage device that combines the high energy density of lithium-ion batteries with the high power density and long lifespan characteristics of double-layer supercapacitors (EDLC), filling the performance gap between the two.

Features:
1. High energy density

It is 3-5 times that of traditional double-layer capacitors (EDLC) (about 10-40 Wh/kg), but lower than lithium batteries (150-250 Wh/kg).

Under the same energy, the volume is smaller than EDLC.

2. Extremely high power density

It can achieve high current charging and discharging in seconds or even milliseconds (5000~20000 W/kg).

Suitable for scenarios that require instantaneous high-power output/input.

3. Long cycle life

The deep charge discharge cycle can reach 50000-100000 times, which is tens of times more than that of lithium batteries (about 1000-3000 times).

4. Wide working temperature range

Excellent low-temperature performance, capable of stable operation in environments ranging from -40 ℃ to+70 ℃.

Solved the problem of significant capacity degradation of lithium batteries at low temperatures.

5. Low self discharge rate

Far lower than traditional supercapacitors, the battery retention rate is high after long-term static storage.

6. High security

Only shallow lithium insertion occurs, without the risk of overcharging, lithium deposition, and thermal runaway of lithium batteries.

Applications：
1. Automotive field

Intelligent start stop system: supports frequent engine starts, instantly provides high current, and extends battery life.

Braking energy recovery: Efficiently recover the braking energy of the vehicle, instantly fill it up and then release it, saving energy and reducing consumption.

2. Rail transit

Tram/high-speed rail: used for braking energy recovery, short-term auxiliary power, and compensation for grid voltage fluctuations.

3. Industry and Energy

Wind power/photovoltaic: Smooth power generation fluctuations and participate in grid frequency regulation (AGC).

Heavy machinery: Potential energy recovery and instantaneous high-power output of port cranes and forklifts.

UPS/Backup Power Supply: Millisecond level emergency power supply for servers and industrial equipment in the event of a power outage.
4. Consumer Electronics and the Internet of Things

Intelligent instruments: smart water meter, gas meter ETC， Low temperature resistance, long lifespan, and maintenance free.

Pulse equipment: camera flash, laser equipment, providing instant high brightness energy.
