Harnessing sea pineapples and blood waste for metal-air-battery catalysts

https://techxplore.com/news/2022-02-harnessing-sea-pineapples-blood-metal-air-battery.html

"carbonization of cellulose nanofibers within sea pineapple shells produces high-quality carbon that, when mixed with blood waste from the livestock industry, boasts electrical performances similar to that of rare metals. The finding is expected to be applied to next-generation energy devices such as fuel cells, metal-air batteries, and shows the potential to act as the electrocatalyst for water electrolysis systems"
