Abstract While solid-state batteries are tantalizing for achieving improved safety and higher energy density, solid ion conductors currently available fail to satisfy the rigorous requirements for battery electrolytes and electrodes. Inorganic ion conductors allow fast ion transport, but their rigid and brittle nature prevents good interfacial contact and impedes device integration and stability. Conversely, flexible polymeric ion conductors provide better interfacial compatibility and mechanical tolerance, but suffer from inferior ionic conductivity (< 10−5 S cm−1 at room temperature) due to the coupling of ion transport with the polymer chain motion1-3. In this work, we report a general design strategy for achieving one-dimensional (1D), high-performance polymer solid-state ion conductors through molecular channel engineering, which we demonstrate via Cu2+-coordination of cellulose nanofibrils. The cellulose nanofibrils by themselves are not ionic conductive; however, by opening the molecular channels between the cellulose chains through Cu2+ coordination we are able to achieve a Li-ion conductivity as high as 1.5×10−3 S cm−1 at room temperature—a record among all known polymer ion conductors. This improved conductivity is enabled by a unique Li+ hopping mechanism that is decoupled from the polymer segmental motion. Also benefitted from such decoupling, the cellulose-based ion conductor demonstrates multiple advantages, including a high transference number (0.78 vs. 0.2–0.5 in other polymers2), low activation energy (0.19 eV), and a wide electrochemical stability window (4.5 V) that accommodate both Li metal anode and high-voltage cathodes. Furthermore, we demonstrate this 1D ion conductor not only as a thin, high-conductivity solid-state electrolyte but also as an effective ion-conducting additive for the solid cathode, providing continuous ion transport pathways with a low percolation threshold, which allowed us to utilize the thickest LiFePO4 solid-state cathode ever reported for high energy density. This approach has been validated with other polymers and cations (e.g., Na+ and Zn2+) with record-high conductivities, offering a universal strategy for fast single-ion transport in polymer matrices, with significance that could go far beyond safe, high-performance solid-state batteries.

Powder Metallurgy Route

The solid state batteries (SSBs) were prepared by powder metallurgy route. For making SSBs, a special die was designed. LiNiO2 and face centre cubic (fcc) TiB powders [1] were used to make cathodes for SSBs while such metals as Zn or Mg were used to make anodes. The SSBs made with LiNiO2 powder generated relatively low currents (1 to 2 ?A) and voltage (0.4~0.9 V) at room temperature. The SSBs made with fcc-TiB cathode generated more power than do the SSBs made with LiNiO2 powder.
