Sandia testing method yields pathway to better, longer-lasting solid-state batteries

Green Car Congress

Here, we combine two operando methods, Kelvin probe force microscopy (KPFM) and neutron depth profiling (NDP), to identify the rate-limiting interface in operating Si-LiPON-LiCoO 2 solid-state batteries by mapping the contact potential difference (CPD) and the corresponding Li distributions. —Alec Talin, co-corresponding author.

UMD team develops new high-performance solid-state ion-conducting membrane for Li batteries

Green Car Congress

Researchers at the University of Maryland have developed a novel, flexible, solid-state, ion-conducting membrane based on a 3D ion-conducting ceramic nanofiber network. The 3D ion-conducting network is based on percolative garnet-type Li 6.4 La 3 Zr 2 Al 0.2 mA/cm 2 for around 500 h and a current density of 0.5
