Jülich Researchers Developing Fast-Charging Solid-State Batteries

Test set-up for the solid-state battery: the battery of the size of a button cell is located in the middle of the acrylic glass casing, which ensures permanent contact with the battery. The patented concept is based on a favorable combination of materials. The components - anode, cathode, and electrolyte were all made from different phosphate compounds to enable charging rates greater than 3C (at a capacity of about 50 mAh/g).

Low current is considered one of the biggest hurdles in the development of solid-state batteries; it is the reason why the batteries take a relatively long time to charge fully—some 10 to 12 hours for a solid-state battery.  Now, researchers at Jülich Forschungzentrum have introduced a new concept battery that allows currents up to ten times greater during charging and discharging than previously described in the literature.  Their battery takes less than an hour to recharge.
