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. The battery, described in a paper in the journal ACS Applied Materials and Interfaces , uses a monolithic all-phosphate concept based on screen-printed thick LiTi 2 (PO 4 ) 3 anode and Li 3 V 2 (PO 4 ) 3 cathode composite layers on a densely sintered Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 solid electrolyte. With the concepts described to date, only very small charge and discharge currents were […]
