Synthesis and Performance of Functional Ceramic-coated Separator for Lithium-ion Battery [PDF]
, 2015 锂离子电池被广泛用于便携设备领域，也被认为是最具有应用前景的电动汽车动力电池体系。但其现有体系的工作模式（尤其是作为电动汽车的动力电源时）在技术上仍然存在巨大的安全隐患。隔膜是锂离子电池中防止正负极材料直接接触而造成短路的隔板，是保障锂离子电池安全的一大关键因素。目前，商品化的液态锂离子电池大多选用微孔聚烯烃膜作为隔膜，它虽具有适宜的孔径、稳定的化学性能、足够的机械强度等优点，但由于在高温下尺寸稳定性差，容易收缩甚至熔化破膜，造成电池内部短路，可能导致电池发生热失控进而起火爆炸 ...

Integrative Conservation, Volume 4, Issue 4, Page 641-651, December 2025.Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...

Gaoya dianqi, 2023 电池储能系统被认为是解决可再生能源的不确定性和不平衡性导致的功率不足和频率波动的有效途径。基于此，文中提出了一种基于电池的荷电状态SOC(state of charge)的电池储能系统混合控制策略。首先，文中将电池的SOC、调频和调峰需求划分为不同的区域，并对调频和调峰提出相应的控制策略，提出SOC自恢复控制策略。之后提出储能的混合控制策略，基于电池储能的SOC，将储能的调频与调峰功能与SOC自恢复策略相结合，实现储能对电力系统的优化。最后通过仿真分析验证该控制策略的合理性与应对可再生能源波动的能力。
