Special Issue Information

Dear Colleagues,

Thermal safety issues, such as thermal runaway, fire, and the explosion of lithium-ion batteries (LIBs), have attracted public attention. Many accidents show that the thermal runaway of LIBs is currently the main cause of most fire and explosion accidents. On the other hand, the risk of the thermal runaway propagation of battery modules is high, and the propagation speed is fast, which often causes serious loss of life and property and adverse social impacts. Therefore, avoiding the thermal runaway of LIB modules and inhibiting the propagation of thermal runaway is an important requirement for developing LIBs. In-depth research on thermal runaway risk management and control methods has important scientific significance and is also an international hot frontier. 

This Special Issue will address the development of the thermal safety of LIBs. Topics of interest for publication include, but are not limited to:

  • High-safety and high-performance battery design;
  • The development of safety additive materials for LIB;
  • Insights into thermal runaway mechanisms and thermal propagation mitigation;
  • Safety tests (mechanical, electrical, thermal abuse);
  • Degradation mechanisms and identification, elucidation, and diagnosis technology;
  • Thermal management (liquid cooling, air cooling, phase change materials cooling, coupled cooling, etc.);
  • Mechanism, characteristics, and propagation of battery thermal runaway, fire, and explosion;
  • Risk assessment and optimal safety control and emergency management;
  • The development, design, and utilization of detection and early warning systems;
  • Thermal runaway propagation, fire, and explosion suppression.

Although phase change materials (PCMs) exhibit effective performance in the thermal management of lithium-ion batteries (LIBs), their development is limited by low thermal conductivity and susceptibility to leakage during the solid–liquid phase transition. To address these challenges and enhance thermal management capabilities, this study introduces a novel composite phase change material (CPCM) synthesized by physically mixing paraffin (PA), expanded graphite (EG), and bacterial cellulose (BC). The thermal performance of CPCMs with varying BC proportions is evaluated, and their impact on temperature control in battery thermal management systems (BTMS) is assessed. The results show that the addition of EG and BC significantly improves the thermal conductivity of the CPCM, reaching a value of 1.39 W·m−1·K−1. This also enhances the uniformity of temperature distribution within the battery module and reduces CPCM leakage. By comparing temperature variations within the battery module under different operating conditions, it was found that the intricate network structure of the CPCM promotes uniform temperature distribution, effectively mitigating temperature rise. Consequently, the maximum temperature and maximum temperature difference within the battery module were maintained below 47 °C and 4 °C, respectively. Compared to a system without phase change material at a 3C discharge rate, the maximum cell temperature, maximum module temperature, and maximum temperature difference were reduced by 32.38%, 26.92%, and 34.94%, respectively. These findings provide valuable insights for the design and optimization of BTMS. Full article
