Porous ceramics are lightweight materials with diverse pore structures and are widely applied in areas such as thermal insulation, sound absorption, filtration, catalysis, and energy storage. However, excessive shrinkage during the sintering process of porous ceramics leads to cracking and deterioration, posing significant challenges for achieving complex shapes. Despite its importance, the field of low sintering shrinkage porous ceramics has not received sufficient attention. This review systematically discusses the principles and progress in the development of low sintering shrinkage porous ceramics. First, we introduce the characteristics of various preparation methods, including partial sintering, particle-stabilized foaming, gel-casting, foam-gelcasting, and additive manufacturing (AM). We then explain three primary principles of low sintering shrinkage from the perspectives of the volume effect and mass transfer processes. This review focuses on the properties and applications of typical low sintering shrinkage ceramics such as mullite and alumina, particularly their mechanical properties and thermal conductivity as thermal insulation and ceramic cores. Finally, we summarize the current state and present future perspectives on low sintering shrinkage porous ceramics.

The electrochemical energy storage technologies, with lithium-ion batteries at the forefront, have made significant contributions to alleviating the global energy crisis and environmental pollution. Assessing the state of health (SOH) of lithium-ion batteries is of paramount importance for their longterm safe and stable operation. Moreover, the constant voltage (CV) charging stage, known for its stability and significantly influences aging. Therefore, this paper proposes a hybrid health state estimation method based on health features extracted during the CV charging stage. Firstly, the CV stage of lithiumion batteries is analyzed, and five health indicators (HIs) are extracted. Pearson correlation analysis is then conducted to assess the interrelationships between the HIs and SOH. Subsequently, a PSO-SVR hybrid model is established to estimate the SOH, where Particle Swarm Optimization (PSO) is employed to tune the parameters of the Support Vector Regression (SVR) model. Finally, the accuracy of the method is validated using battery data from the Tongji University Clean Energy Vehicle engineering Center, resulting in an estimated root mean square error (RMSE) and mean absolute percentage error (MAPE) of less than 1.5%. © 2024 IEEE.
