APPLICATIONS OF TECHNOLOGY:
- Lithium ion batteries
- Improved safety
- High temperature operation capability
Despite the many advantages and wide commercial usage of lithium-ion (Li-ion) batteries, there remain substantial performance limitations and safety concerns. Since Li-ion batteries self-heat naturally as they are operated, developing Li-ion batteries with high temperature operation capability is vital for overall safety and reliability.
Researchers at Lawrence Berkeley National Laboratory have developed an electrolyte structure for Li-ion batteries that is formed by embedding boron nitride aerogels (BNAGs) or boron nitride nanotubes (BNNTs) into an electrolyte to increase the electrolytic temperature stability. The advantages in chemical intertness, thermal stability, and high surface area of BNAG and BNNTs elevate the reliable and safe battery operation temperature to 190°C while still maintaining high capacity and cyclability.
