Thermal Properties of La1−x A x CoO3 (A = Ca and Ba)

Defect-Induced Properties and Thermodynamics of La0.5Ba0.5CoO3–δ

“…7 in comparison with previously reported data for both La 0.5 Ba 0.5 CoO 3 18 and LaCoO 3 . [46][47][48] For the latter, previously reported calorimetric data 46,47,49 agree fairly well with each other as well as with the recent thermodynamic assessment results. 50 On the contrary, the heat capacity calculated for LaCoO 3 by Thakur et al 48 significantly exceeds the results of others 46,47 (see Fig.…”

A Structural Battery and its Multifunctional Performance

“…Furthermore, almost all of these demonstrate poor multifunctional performance, where either the electrical or the mechanical performance is prioritized. For example, Thakur and Dong [ 27 ] reported an energy density of 24 Wh kg −1 at an elastic modulus of only 0.29 GPa, whereas Meng et al [ 28 ] demonstrated a structural battery material with an elastic modulus of 7.0 GPa but a low energy‐storage capability of 1.4 Wh kg −1 . Moyer et al reported a multifunctional device, exploiting CFs as collectors.…”
