The global lithium-ion (li-ion) battery market size is currently booming and it is expected to grow from $41.1 billion in 2021 to $116.6 billion by 2030. Thus, it is already a well-established fact that li-ion batteries are an important part of the energy transition.

Now, a team of researchers based at the University of Indonesia’s Faculty of Engineering, Metallurgy and Materials Engineering Department (DTMM FTUI) have developed a novel use for used coffee grounds as a material for li-ion batteries. What’s more, this material has been specifically designed to be used for electric vehicle batteries.
The idea was originally published in the Journal of Cleaner Production and further developed this year.
The idea to use coffee came from the fact that the research team saw an abundance of waste coffee grounds and in the spirit of good research, they soon discovered that the grounds could be turned into graphene.
Lithium-Ion Batteries
Li-ion batteries come in all shapes and sizes these days and they can use a number of different materials in their composition. The most frequently used Li-ion batteries are found in portable electronic devices such as cellphones and laptops, these batteries use a combination of lithium cobalt oxide (cathode) and graphite (anode).
Common cathode materials used in EVs and hybrid automobiles include lithium manganese oxide and lithium iron...
