据“上海航天”消息，中国航天科技集团第八研究院811所与南开大学科研团队，在国际顶级学术期刊自然发表锂电池技术首创成果——成功研制适用于高能量密度及低温场景的氢氟烃电解液，标志中国锂电池核心技术取得新突破，有望实现现有锂电池续航力成倍提升与耐低温性能显著增强。
811所研究员李永介绍，当前市场主流锂电池室温能量密度约300瓦时/千克，零下20℃时骤降至150瓦时/千克以下；而该成果可使锂电池室温能量密度超700瓦时/千克，零下50℃仍保持约400瓦时/千克。同等质量下，室温储电能力提升2至3倍以上，能将电动汽车续航从五六百公里提升至一千公里以上，且可在零下70℃极端低温下正常工作。
电解液是锂电池正负极间的离子传导介质，承担离子传输功能，对电池能量效率、工作稳定性及温度适应性至关重要。传统电解质溶剂以氧（O）基、氮（N）基配体为主，虽对锂盐溶解性强ϼ..
