| 1 | Nonlinear health evaluation for lithium-ion battery within full-lifespan显示文摘Lithium-ion batteries(LIBs), as the first choice for green batteries, have been widely used in energy storage, electric vehicles, 3C devices, and other related fields, and will have greater application prospects in the future. However, one of the obstacles hindering the future development of battery technology is how to accurately evaluate and monitor battery health, which affects the entire lifespan of battery use. It is not enough to assess battery health comprehensively through the state of health(SoH) alone, especially when nonlinear aging occurs in onboard applications. Here, for the first time, we propose a brand-new health evaluation indicator—state of nonlinear aging(SoNA) to explain the nonlinear aging phenomenon that occurs during the battery use, and also design a knee-point identification method and two SoNA quantitative methods. We apply our health evaluation indicator to build a complete LIB full-lifespan grading evaluation system and a ground-to-cloud service framework, which integrates multi-scenario data collection, multi-dimensional data-based grading evaluation, and cloud management functions. Our works fill the gap in the LIBs’ health evaluation of nonlinear aging, which is of great significance for the health and safety evaluation of LIBs in the field of echelon utilization such as vehicles and energy storage. In addition, this comprehensive evaluation system and service framework are expected to be extended to other battery material systems other than LIBs, yet guiding the design of new energy ecosystem. | Heze You Jiangong Zhu Xueyuan Wang Bo Jiang Hao Sun Xinhua Liu Xuezhe Wei Guangshuai Han Shicong Ding Hanqing Yu Weihan Li Dirk Uwe Sauer Haifeng Dai | 2022 | Journal of Energy Chemistry2022，31，9： | 4 |

| 5 | The First High-quality Reference Genome of Sika Deer Provides Insights into High-tannin Adaptation显示文摘Sika deer are known to prefer oak leaves,which are rich in tannins and toxic to most mammals;however,the genetic mechanisms underlying their unique ability to adapt to living in the jungle are still unclear.In identifying the mechanism responsible for the tolerance of a highly toxic diet,we have made a major advancement by explaining the genome of sika deer.We generated the first high-quality,chromosome-level genome assembly of sika deer and measured the correlation between tannin intake and RNA expression in 15 tissues through 180 experiments.Comparative genome analyses showed that the UGT and CYP gene families are functionally involved in the adaptation of sika deer to high-tannin food,especially the expansion of the UGT family 2 subfamily B of UGT genes.The first chromosome-level assembly and genetic characterization of the tolerance to a highly toxic diet suggest that the sika deer genome may serve as an essential resource for understanding evolutionary events and tannin adaptation.Our study provides a paradigm of comparative expressive genomics that can be applied to the study of unique biological features in non-model animals. | Xiumei Xing Cheng Ai Tianjiao Wang Yang Li Huitao Liu Pengfei Hu Guiwu Wang Huamiao Liu Hongliang Wang Ranran Zhang Junjun Zheng Xiaobo Wang Lei Wang Yuxiao Chang Qian Qian Jinghua Yu Lixin Tang Shigang Wu Xiujuan Shao Alun Li Peng Cui Wei Zhan Sheng Zhao Zhichao Wu Xiqun Shao Yimeng Dong Min Rong Yihong Tan Xuezhe Cui Shuzhuo Chang Xingchao Song Tongao Yang Limin Sun Yan Ju Pei Zhao Huanhuan Fan Ying Liu Xinhui Wang Wanyun Yang Min Yang Tao Wei Shanshan Song Jiaping Xu Zhigang Yue Qiqi Liang Chunyi Li Jue Ruan Fuhe Yang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，1： | 1 |

| 7 | Research on the impact of high-temperature aging on the thermal safety of lithium-ion batteries显示文摘Understanding the thermal safety evolution of lithium-ion batteries during high-temperature usage conditions bears significant implications for enhancing the safety management of aging batteries.This work investigates the thermal safety evolution mechanism of lithium-ion batteries during high-temperature aging.Similarities arise in the thermal safety evolution and degradation mechanisms for lithium-ion batteries undergoing cyclic aging and calendar aging.Employing multi-angle characterization analysis,the intricate mechanism governing the thermal safety evolution of lithium-ion batteries during high-temperature aging is clarified.Specifically,lithium plating serves as the pivotal factor contributing to the reduction in the self-heating initial temperature.Additionally,the crystal structure of the cathode induced by the dissolution of transition metals and the reductive gas generated during aging attacking the crystal structure of the cathode lead to a decrease in thermal runaway triggering temperature.Furthermore,the loss of active materials and active lithium during aging contributes to a decline in both the maximum temperature and the maximum temperature rise rate,ultimately indicating a decrease in the thermal hazards of aging batteries. | Guangxu Zhang Xuezhe Wei Siqi Chen Gang Wei Jiangong Zhu Xueyuan Wang Guangshuai Han Haifeng Dai | 2023 | Journal of Energy Chemistry2023，，12： | 0 |

| 10 | Thermal safety boundary of lithium-ion battery at different state of charge显示文摘Thermal runaway(TR)is a critical issue hindering the large-scale application of lithium-ion batteries(LIBs).Understanding the thermal safety behavior of LIBs at the cell and module level under different state of charges(SOCs)has significant implications for reinforcing the thermal safety design of the lithium-ion battery module.This study first investigates the thermal safety boundary(TSB)correspondence at the cells and modules level under the guidance of a newly proposed concept,safe electric quantity boundary(SEQB).A reasonable thermal runaway propagation(TRP)judgment indicator,peak heat transfer power(PHTP),is proposed to predict whether TRP occurs.Moreover,a validated 3D model is used to quantitatively clarify the TSB at different SOCs from the perspective of PHTP,TR trigger temperature,SOC,and the full cycle life.Besides,three different TRP transfer modes are discovered.The interconversion relationship of three different TRP modes is investigated from the perspective of PHTP.This paper explores the TSB of LIBs under different SOCs at both cell and module levels for the first time,which has great significance in guiding the thermal safety design of battery systems. | Hang Wu Siqi Chen Yan Hong Chengshan Xu Yuejiu Zheng Changyong Jin Kaixin Chen Yafei He Xuning Feng Xuezhe Wei Haifeng Dai | 2024 | Journal of Energy Chemistry2024，91，4： | 0 |
