Faster charger: Huawei presented a new Li-ion battery at the Battery Symposium in Japan, said to charge ten times faster than current variants, reaching 68% capacity in two minutes. According to Huawei, this is made possible by bonding heteroatoms to graphite anodes, saying the technology could revolutionize the EV market.

Fool’s gold battery: Researchers from Empa and ETH Zurich have developed a battery made from iron, sulfur, sodium and magnesium, a combination also referred to as “fool’s gold.” The elements are more abundant and cheaper than lithium and especially fit for stationary batteries. So far, however, they are not powerful enough for electric cars.

Ultrasmall nanoparticles: Unlike using bulk iron pyrite, researchers at Vanderbilt University found that using iron pyrite dots in sodium and lithium works, because the iron can move close to the surface. Moreover, the sodium and lithium reacts with the sulphur in the iron pyrite, changing its form to store energy.
