      abstract     = {Safety features of Li-ion batteries are a high priority
                      requirement as their adoption in electric vehicles and
                      day-to-day electronic devices is continuously increasing.
                      The liquid electrolytes that are typically used in
                      traditional Li-ion batteries are flammable, especially at
                      higher operating voltages and temperatures. By contrast, an
                      all-solid-state battery (ASSB) makes use of solid
                      electrolyte instead of liquid electrolyte, which reduces the
                      risk of flammability. However, the solid-solid
                      electrolyte-electrode interface in ASSBs introduces
                      different sets of challenges from the traditional
                      liquid-solid electrode-electrolyte interface. First, in
                      batteries containing liquid electrolytes entire surface of
                      electrode particles are wetted by electrolytes, whereas the
                      electrode and solid electrolyte particles in ASSBs are
                      connected primarily at point contacts, which are limited in
                      terms of their numbers (as not all electrode particles are
                      in direct contact with electrolyte particles), therefore
                      ionic transport is basically restricted, diminishing the
                      specific capacity of these batteries. Decomposition
                      reactions at the electrode-electrolyte interfaces during
                      battery cycling cause the formation of passivating layers
                      and as well as electrode volume changes during battery
                      cycling result in loss of contacts between electrode and
                      electrolyte particles, further decreasing direct ion
                      exchange pathways. Second, inhomogeneous (de)lithiation
                      through point contacts can induce strain, which affects
                      electrode mechanical integrity leading to capacity fade.
                      Operando transmission electron microscopy (TEM) allows for
                      the visualization of (de)lithiation processes in electrode
                      materials at a single particle level in real-time. In our
                      recent research, we have utilized the volume change property
                      of Si nanoparticles during (de)lithiation to understand the
                      interface kinetics of an ASSB during cycling. Following the
                      safty aspect, aquous based Zn-batteris are also gathering
                      attention. In this resepect, recent works on Zn-ion
                      batteries using liquid phase TEM will also be discussed.},
