Direct Observation of Reversible Heat Absorption in Li-ion Battery Enabled by Ultra-Sensitive Thermometry
Zhe Cheng, Xiaoyang Ji, David G. Cahill
The reversible heat in lithium-ion batteries (LIBs) due to entropy change is fundamentally important for understanding the chemical reactions in LIBs and developing proper thermal…
Good Solid-State Electrolytes Have Low, Glass-like Thermal Conductivity
Zhe Cheng, Beniamin Zahiri, Xiaoyang Ji +4
Management of heat during charging and discharging of Li-ion batteries is critical for their safety, reliability, and performance. Understanding the thermal conductivity of the mat…
Thermal Visualization of Buried Interfaces by Transient and Steady-State Responses of Time-Domain Thermoreflectance
Zhe Cheng, Fengwen Mu, Xiaoyang Ji +6
Thermal resistances from interfaces impede heat dissipation in micro/nanoscale electronics, especially for high-power electronics. Despite the growing importance of understanding i…
Thermal Conductivity Mapping of Oxidized SiC SiC Composites by Time Domain Thermoreflectance with Heterodyne Detection
Xiaoyang Ji, Zhe Cheng, Ella Kartika Pek +1
Silicon carbide silicon carbide (SiC SiC) composites are often used in oxidizing environments at high temperatures. Measurements of the thermal conductance of the oxide layer provi…
