Abstract This study investigated the day‐to‐day variability of ionospheric electron temperature ( T e ) over Sanya using newly built Incoherent Scatter Radar (SYISR; 18.3°N, 109.6°E, dip latitude: 12.8°N). The 24 days observations with transmitted beams encoded by alternating code and directed toward zenith provided profiles during April–May 2022. spatial‐temporal resolution was as precise 4.5 km ∼120 s. thus revealed, which strong in sunrise peak region (above ∼260 km, duration increases...
Ternary lithium-ion batteries (LIBs) have the advantages of high energy density and charging efficiency, they are preferred source for long-life new vehicles. However, when thermal runaway (TR) occurs in ternary LIB, an open flame is easily produced. The burning phenomenon intense, rapid TR propagation high; consequently, vehicle-level fire accidents induced. These become biggest obstacle restricting batteries’ development. Therefore, this study investigates behavior LIBs at cell module...
