dc.description.abstract | All-solid-state battery performance is strongly dependent on effective charge transfer at both 1) the interface of the active particles and 2) through the interstitial regions of composite cathode. Design of the composite cathode is further complicated by the necessity to limit the amount of conductor additives in order to attain high energy density. These requirements present a difficult design challenge for the composite cathode. Here we investigate the extent to which the mixing order of the three components in the composite cathode impacts the charge transfer and cell performance. We test a total of 5 mixing protocols and find that the initial discharge capacity and the rate capability varies significantly with mixing order. It is shown that the location of the electron conductive carbon is particularly critical for cell performance due to its limited quantity in the composite cathode. Mixing protocols that concentrate the carbon at the active particle interface lowers the interfacial resistance leading to higher discharge capacity. Mixing protocols that place more carbon in the interstitial regions improves the electron path conductivity and is found to correlate with higher rate capability. Based on these results we demonstrate a mixing protocol that achieves both higher discharge capacity and better rate performance for all-solid-state batteries. | - |
