市科委組織召開國際前沿動力電池閉門技術專家研討會

為加強在前沿動力電池領域國內外技術交流與合作,并進一步梳理我市前沿動力電池技術發展重點方向。2017年8月31日,市科委主任許強參加,副主任張繼紅在京主持召開“國際前沿動力電池閉門技術專家研討會”。  

市科委組織召開國際前沿動力電池技術專家研討會 

會上,國內外著名專家美國“電池500”研究中心主任、斯坦福大學崔屹教授,美國機械工程師學會(ASME)院士及賓夕法尼亞州立大學王朝陽教授分別做了《關于下一代高能鋰電池材料和技術》和《開發高比能、超長壽命、快充電池的新思路》的主題演講,中科院長春應用化學所張新波研究員、北京理工大學吳鋒教授、中科院物理研究所李泓研究員等11位國內專家介紹了鋰空氣電池現狀與未來、固態鋰離子電解質及全固態電池基礎研究與產業化、下一代鋰電池技術路線分析等前沿動力電池技術。國內外專家共同就前沿動力電池的技術發展方向、在新能源汽車領域的應用前景等內容進行了交流和討論。

高比能、長壽命、快充電池是當今電動汽車急需的動力系統,采用新原理、新材料、新組件有望進一步提升電池單體的性能。崔屹教授提出未來20年動力電池單體能量密度提升技術路徑圖,采用固態電解質組裝固態電池是提升電池安全性的可行思路。王朝陽教授介紹了其研發團隊發明的電芯內部自加熱技術,12.5秒可以將單體電池從零下20℃加到0℃以上。作為冬奧會舉辦地之一的張家口區域極寒時溫度降至零下23℃,電池自加熱技術應用于新能源汽車動力電池,可服務綠色冬奧。鋰硫電池、鋰空氣電池、固態電池這些新體系電池具有實現更高比能量儲能的潛力。

張繼紅副主任指出,動力電池是新能源汽車的關鍵零部件之一,新能源汽車的快速發展對動力電池能量密度、安全性等性能提出了更高的要求。通過本次研討會進一步梳理了前沿動力電池技術的發展重點和難點。市科委將密切關注前沿動力電池技術的發展,下一步將通過產學研和國際合作,針對前沿動力電池的重點技術,積極研發電動汽車用300Wh/kg級三元系高比能量鋰離子電池,組織開展固態鋰電池等前沿電池及關鍵材料的技術攻關及工程化技術開發,推進北京市新能源汽車前沿動力電池技術的發展。

科技部高新技術發展及產業化司能源與交通處處長武平,市科委新能源與新材料處處長許心超,北京市新能源汽車發展促進中心主任牛近明、副主任韋瑾參會。
