Existing lithium-ion batteries rely on the movement of lithium ions between the anode and cathode–and back–as the battery charges and discharges.
It’s one of the best options we have for powering electric vehicles (and most consumer electronic devices, for that matter) but there’s still room for improvement.
Researchers at Stanford University have published a report in the Nature Nanotechnology journal detailing the creation of a pure lithium anode, potentially boosting battery efficiency by a large margin over today’s units.
According to Phys.org, a pure lithium anode is considered the ‘Holy Grail’ of battery design, returning the usual improved-battery benefits: higher energy density, lighter weight and more power.
In an existing lithium-ion battery, the anode is typically made of graphite or silicon. These are largely used for their stability, rather than their efficiency. » Read the rest of this entry «
