A quasi-solid-state Li-Te battery with flexible gel polymer electrolyte, porous carbon/tellurium cathode, and lithium metal anode has been developed, showing controllable ionic conductivity and excellent cycling stability. Compared to S and Se counterparts, the Li-Te battery exhibits good rate capability due to the high electrical conductivity of Te and excellent interfacial stability.
A quasi-solid-state Li-Te battery is developed by using a flexible gel polymer electrolyte (GPE), porous carbon/tellurium cathode, and lithium metal anode. The ionic conductivity of GPE is controllable and reaches up to 8.0 x 10(-4) S cm(-1) at 25 degrees C. The good interfacial contact with Li metal ensures excellent cycling stability in Li/GPE/Li symmetric cells. Moreover, it is found that, compared to S and Se counterparts, the Li-Te battery exhibits good rate capability due to the high electrical conductivity of Te and excellent interfacial stability among GPE, Li, and Te. This work provides several facile strategies to develop safe and high-performance solid-state Li-Te batteries. (C) 2021 Elsevier Inc. All rights reserved.
