Garnets are a promising solid electrolyte family due to high mechanical strength, ionic conductivity, wide electrochemical stability window, and processability. However, dendrite formation, physical contact loss, cathode interphase formation, and limited ion conduction pathways in cathode during cycling are challenges that need to be addressed for long-term and safe operation of garnet-based All-Solid-State batteries(ASSB) [1]. Interfacial inhomogeneities, irregular electrodeposition and electrodissolution of Li-metal, heterogenous current distribution at the interface, interfacial defects, stress concentration, diffusion limitation of Li and lower dynamic properties of solid electrolytes are amongst the main reasons identified for dendrite formation and physical contact loss [2]. Significant efforts are reported in the literature to suppress dendrite formation and ensuring interface contact via interfacial coatings, SE material modifications, and modified operating conditions all of which either increases system complexity or cost of ASSB operation [3]. Additionally, these solutions have been investigated for lower current densities compared to what will be ideally required to operate a full ASSB (1C – 10C). Higher current density will lead to inhomogeneity in current distribution and pore generation leading to dendrite formation and cell failure. In this work, we demonstrate several non-destructive electrochemical strategies for the removal of Li-dendrites and ensuring physical contact at Li | LALZO interface during long-term cycling [4]. The initial results on symmetric cells indicate that dendrite can be completely removed from the bulk of solid electrolytes at lower current densities. The combination of various current ranges with specific cut-off voltages leads to better interfacial contact at Li | LALZO interface. Similar electrochemical strategies are being investigated for full ASSBs with Li | LALZO | LFP configuration at various temperatures and pressure ranges. The obtained results illustrate that the battery cells can be repaired, improved, and rescued from the failure mode and enable longer life.
