The utilization of inorganic ferroelectric ceramics is thought to be an effective approach to enhance output performances of triboelectric nanogenerators (TENGs). However, the large remnant polarization from ferroelectric ceramics traps partial charges on electrodes all the time, which limits the performance improvement of TENGs and their applications in energy harvesting and self-powered sensing. Herein, achieving absolute exploitation of dielectric polarization from inorganic ceramics for significant performance enhancement is unprecedentedly proposed by using antiferroelectric ceramics with large polarization difference. The features of nearly zero remnant polarization and large maximum polarization for antiferroelectric ceramics perfectly match the working cycle mechanism of TENGs, enabling all polarization induced charges to flow through the external circuit. Based on this concept, an ideal flexible Pb_0.94La_0.04Zr_0.98Ti_0.02O₃ (PLZT) antiferroelectric ceramic inner-layer with record-high polarization difference is developed and assembled into a triboelectric nanogenerator (PLZT-TENG). The PLZT-TENG exhibits an outstanding output of 13.5 nC cm^–2, a 1.6-fold enhancement compared with the TENG with a PbZr_0.52Ti_0.48O₃ (PZT) ferroelectric ceramic inner-layer. Thanks to excellent flexibility, stability, and durability, the PLZT-TENG can serve as a biomechanical energy harvester and a self-powered sensor to be applied in practice. Our findings open a generic and upgradable way to the evolution and optimization of TENGs.

无机铁电陶瓷的利用被认为是增强摩擦电纳米发电机（TENGs）的输出性能的有效方法。但是，铁电陶瓷产生的大量残留极化始终将部分电荷捕获在电极上，这限制了TENG的性能改进及其在能量收集和自供电传感中的应用。在此，通过使用具有大的极化差的反铁电陶瓷，前所未有地提出了从无机陶瓷中绝对地利用介电极化以显着提高性能。反铁电陶瓷的几乎零极化和最大极化大的特征与TENG的工作循环机制完全匹配，使所有极化感应的电荷流过外部电路。基于此概念，理想的柔性铅开发出具有创纪录的高极化差的_0.94 La _0.04 Zr _0.98 Ti _0.02 O ₃（PLZT）反铁电陶瓷内层，并将其组装成摩擦电纳米发电机（PLZT-TENG）。PLZT-TENG的输出功率高达13.5 nC cm ^-2，比具有PbZr _0.52 Ti _0.48 O ₃（PZT）铁电陶瓷内层的TENG功率高1.6倍。由于具有出色的柔韧性，稳定性和耐用性，PLZT-TENG可以用作生物力学能量采集器和可在实践中应用的自供电传感器。我们的发现为TENG的发展和优化开辟了一种通用且可升级的方式。
