Lithium-ion capacitors (LIC) itself will outlast the device it powers, providing extended use and value

Lithium-ion capacitors (LIC) are gaining popularity as a safer and more durable alternative to traditional lithium-ion batteries. They are particularly well-suited for large-scale applications where safety and longevity are crucial.

Lithium-ion capacitor (LIC or LiC)

  • A lithium-ion capacitor (LIC or LiC) is a hybrid type of capacitor that falls under the category of supercapacitors.
  • It is called a hybrid because it combines the anode of lithium-ion batteries with the cathode of supercapacitors.
  • The cathode of the LIC is typically made of activated carbon.
  • The anode of the LIC is made of carbon material that is pre-doped with lithium ions.
  • The pre-doping process reduces the potential of the anode and enables a higher output voltage compared to other supercapacitors.

Value for money, supercapacitor and LIC

  • Supercapacitors and LIC (Lithium-ion Capacitors) are both used to serve the trend of longer cycle life and calendar life for equipment.
  • LIC designs with a middle ground of 60Wh/kg have longer cycle life and calendar life compared to the equipment they are fitted in.
  • The difference between a life of 50,000 cycles and one million cycles is usually not significant in the real world.
  • Tesla car battery packs are designed to last 1,500 charging cycles, which translates to about 600,000 km and ten years or more for many users.
  • Industrial and commercial vehicles and their fast chargers can be used twenty times more intensively, so their LIC would last as long as they do, but their LIB (Lithium-ion Batteries) would not.
  • LIC is larger and heavier, but it can act as a useful counterweight, similar to lead-acid traction batteries in industrial vehicles.
  • Some manufacturers claim that LIC with a capacity of 200Wh/kg can last up to 10,000 hours, which can be as long as the equipment it is fitted in.

Diver Insights :

  • The trend towards fit-and-forget engineering is driven by the desire for long-term cost savings and reduced maintenance requirements. Purchasers are willing to pay a higher upfront price for a product that will have lower overall costs over its lifetime.
  • Lithium-ion capacitors (LIC) are gaining popularity as a safer and more durable alternative to traditional lithium-ion batteries. They are particularly well-suited for large-scale applications where safety and longevity are crucial.
  • LIC designs have been found to have a longer cycle life and calendar life compared to the equipment they are installed in. This means that the LIC itself will outlast the device it powers, providing extended use and value.
  • Redox flow batteries (RFB) and lithium-ion batteries (LIB) have different applications in the energy storage industry. RFBs are ideal for longer duration grid and beyond-grid storage, while LIBs are commonly used in heavy electric off-road vehicles and fast chargers.
  • Research indicates that RFB technology will likely move towards hybrid options in the future, combining the advantages of different battery technologies. On the other hand, LIC technology is expected to explore alternative options for further improvements.
  • Graphene, a highly conductive and lightweight material, is proving to be beneficial in the development of lithium-ion battery electrodes. Its unique properties enhance the performance and efficiency of LIBs.
  • While there have been limited advancements in battery supercapacitor hybrids (BSH) beyond LIC, it is possible that future developments may occur in non-LIC BSH technologies. Researchers are continuously exploring new materials and designs to improve energy storage capabilities.
  • The future market demands for energy storage systems include the use of materials that are not scarce or toxic, the ability to bear loads and be stretchable for flexible applications, improved pulse performance for high-power applications, and better charge retention to minimize energy loss over time. Meeting these needs will drive innovation in the energy storage industry.
