Ferroelectric energy harvest and storage cell - III

It is estimated that 71% of the energy generated for transportation is wasted, 66% is wasted in electricity, 20% is wasted in commercial and residential buildings, and 20% is wasted in industry or manufacturing. This wasted energy is primarily in the form of heat. Several solutions have been attempted and implemented to harvest the wasted heat such as those based on Thermoelectrics (TEs), Pyroelectrics (PEs), and Ferroelectrics (FEs). Nonetheless, the FEs are the most efficient active materials in devices working under the thermoelectric and pyroelectric principles. Herein, we show self-charge while discharging with a load. We point out that even if there is a gradient effect while using an air or argon blower, the same effect is observed at a constant temperature. The previous vídeos on this series (I and II) resulted from experiments with Zn/ferroelectric Na-glass composite/C+Cu. This experiment was performed with Zn/ferroelectric Li-glass composite/C+Cu.据测算，交通运输领域所消耗的能源中有71%被浪费，电力生产环节的能源浪费占比达66%，商业与民用建筑领域为20%，工业及制造业领域同样为20%。这些被浪费的能源主要以热能形式存在。 目前已有多种废热回收方案被尝试并落地实施，例如基于热电材料（Thermoelectrics, TEs）、热释电材料（Pyroelectrics, PEs）以及铁电材料（Ferroelectrics, FEs）的回收方案。然而，在遵循热电与热释电原理工作的器件中，铁电材料是效率最高的活性材料。 本文中，我们展示了带负载放电时的自充电现象。我们指出，即便使用空气或氩气鼓风机时存在梯度效应，在恒温条件下仍可观测到相同效应。 本系列此前的第I、II部分研究均基于Zn/铁电钠玻璃复合材料/C+Cu体系完成实验。本次实验采用的是Zn/铁电锂玻璃复合材料/C+Cu体系。
