A breakthrough in lithium-air battery development, points a path to the ‘ultimate’ battery.
Researchers at Cambridge’s Department of Chemistry, have successfully demonstrated a lithium-oxygen battery which has very high energy density.
The so-called ‘ultimate’ battery is more than 90% efficient, and can be recharged more than 2000 times, but say real-life usage is still a decade off.
Professor Clare Grey of Cambridge’s Department of Chemistry, the paper’s senior author, said:
“What we’ve achieved is a significant advance for this technology and suggests whole new areas for research – we haven’t solved all the problems inherent to this chemistry, but our results do show routes forward towards a practical device.”
Dr Tao Liu, also from the Department of Chemistry, and the paper’s first author, said:
“In their simplest form, batteries are made of three components: a positive electrode, a negative electrode and an electrolyte.”
