Web21 sep. 2024 · Lithium-Ionen-Batterien sind bislang die vorherrschende Technologie sowohl in Smartphones und Laptops als auch in den meisten Elektroautos. Das besondere an Graphen-Akkus ist, im Vergleich zu den Lithium-Ionen-Batterien, unter anderem die vergleichsweise wesentlich schnellere Ladezeit. Web16 feb. 2024 · One of the simplest cathode materials is lithium-cobalt-oxide (Li-Co-O 2) and he chose it as an example. “In a lithium-ion battery, what we are trying to do during charging is to take the lithium ions out of the oxide and intercalate, or insert them into a graphite electrode. During discharging, exactly the opposite happens,” explained Abraham.
