Patented Process and Materials for Electrode Surface Engineering
TECHNOLOGY
Redefining the Future of Energy Storage
SeaLion’s Patented technology offers significant performance advancements to lithium-ion battery (LIB). Its Nanoscale Conducting Polymer Coatings are applied directly onto LiB cathodes (and anodes like Silicon) using a patented process. This enhances conductivity, reducing resistance buildup during cycling, and offer elasticity to minimize mechanical degradation. The key features enhancement it brings in are:
- Cycle Life Extension by 10 times
- Charging Time Reduction
- Improved Safety while operating at higher voltages and temperatures
This intends to help the Energy Storage Industry substantially through:
- Decreased Levelized Cost of Storage (LCOS)
- Increased Residual Value
- Enabling the use of Advanced Battery Systems by supporting 5V cathodes that can enhance energy Density.

Plastics that conduct electricity
WHAT WE DO
Inside a lithium-ion battery electrode, millions of active material particles shuttle electric charge. Over time, these particles crack, blocking the flow of ions and electrons and causing the battery storage capacity to degrade. We’ve invented and patented a nanoscale conducting polymer coating that seals these cracks and maintains the charge pathway-extending battery life and performance.
MISSION & VISION
SeaLion Energy solves one of the biggest pain points in electrification:
- Ability to maximize usable battery capacity without reducing the battery life,
- Allowing SAFE battery operation under elevated temperatures and operating voltages and charging speeds.
- Powered by technology invented at Carnegie Mellon University, we are building this super battery in Pittsburgh
Try our materials
- We coat powder (active materials) and electrode sheets
- Our coatings are 10,000 times thinner than a strand of hair
- 10X longer lasting battery cells
- 1−3% of the cell cost
- With a $5–10 materials investment, customers can avoid a $400 battery replacement
- Unlocking a 40X to 80X return.
