Apple maturity detection algorithm based on FPB-DETR

Ting Xue, Zhenzhou Wang, Zhiyong Meng, Xiuqing Zhang et autres

To address the low accuracy and efficiency of apple maturity detection under large-scale, lighting, and occlusion conditions, an improved FPB-DETR detection model based on RT-DETR was proposed. Firstly, a frequency-adaptive dilated convolution (FADC) module was introduced into the backbone network to precisely …

Ethylene Carbonate Free Electrolyte for Wide‐Temperature 4.5 V Lithium‐Ion Battery

Xinbo Zhao, Qilong Yang, Xiuqing Zhang, Yongzhu Fu et autres

ABSTRACT Ethylene carbonate (EC) is a key solvent to establish the stable solid electrolyte interphase (SEI) on the graphite anode in lithium‐ion batteries. However, it decomposes at >4.3 V vs. Li/Li+ and its high melting point (36.4 °C) significantly restricts its applicability …
