| 2 | Thermal Runaway of Lithium-Ion Batteries Employing Flame-Retardant Fluorinated Electrolytes显示文摘Fluorinated electrolytes possess good antioxidant capacity that provides high compatibility to high-voltage cathode and flame retardance;thus,they are considered as a promising solution for advanced lithium-ion batteries carrying both high-energy density and high safety.Moreover,the fluorinated electrolytes are widely used to form stable electrolyte interphase,due to their chemical reactivity with lithiated graphite or lithium.However,the influence of this reactivity on the thermal safety of batteries is seldom discussed.Herein,we demonstrate that the flame-retardant fluorinated electrolytes help to reduce the flammability,while the lithium-ion batteries with flame-retardant fluorinated electrolytes still undergo thermal runaway and disclose their different thermal runaway pathway from that of battery with conventional electrolyte.The reduction in fluorinated components(e.g.,LiPF 6 and fluoroethylene carbonate(FEC))by fully lithiated graphite accounts for a significant heat release during battery thermal runaway.The 13%of total heat is sufficient to trigger the chain reactions during battery thermal runaway.This study deepens the understanding of the thermal runaway mechanism of lithium-ion batteries employing flame-retardant fluorinated electrolytes,providing guidance on the concept of electrolyte design for safer lithium-ion batteries. | Junxian Hou Li Wang Xuning Feng Junpei Terada Languang Lu Shigeaki Yamazaki Anyu Su Yoshiko Kuwajima Yongjiang Chen Tomoya Hidaka Xiangming He Hewu Wang Minggao Ouyang | 2023 | Energy & Environmental Materials2023，6，1： | 1 |
| 3 | Dynamic Assessment of Global Maize Exposure to Extremely High Temperatures显示文摘Exposure to extreme heat can severely harm crop growth and development,and it is essential to assess such exposure accurately to minimize risks to crop production.However,the actual distribution of crops and its changes have neither been examined in sufficient detail nor integrated into the assessments of exposure to ensure their accuracy.By examining the distribution of maize at a high resolution through species distribution modeling,we assessed the past and future exposure of maize to temperatures above 37℃worldwide.Such exposure is likely to be widespread and severe,mainly in the subtropics,and may even expand to the mid-latitudes to encompass some major maize-producing areas.Many areas at both high and low latitudes may become exposed for the first time in the next 20 years.By the 2050 s,the total area exposed could increase by up to 185%to 308.18 million ha,of which the area exposed for over 60 days may increase nearly sevenfold.The average length of exposure may increase by 69%to 27 days,and areas optimally suited to maize planting may see the fastest increase by up to 772%.Extreme heat can threaten global maize production severely,and measures to mitigate that threat and to adapt to it are urgently needed. | Yuan Gao Peng Su Anyu Zhang Ran Wang Jing'ai Wang | 2021 | International Journal of Disaster Risk Science2021，12，5： | 1 |
