格隆匯4月1日丨孚能科技(688567.SH)公佈,公司研發團隊已經開發並驗證了能量密度達到330Wh/kg的下一代電動汽車電池,該動力電池技術限制了硅材料充放電的巨大膨脹,並配合單壁碳納米管導電劑以及新型粘結劑等輔料,構建穩定電極體系。

相比現有石墨負極,330Wh/kg高能量密度電池可大幅降低負極面密度,提升產品的能量密度及充電安全性能,實現電池能量密度和循環性能雙提升。同時,通過化學體系的配合,實現電池的高動力學表現,使電池在零下20℃温度下仍能提供約90%的容量。該動力電池技術,具有高能量密度,併兼具長壽命和高動力學性能的優勢,填補目前行業空白。同時,該電池的高温性能也表現優異,高温存儲和高温循環性能均能高於行業水平。

截至目前,該項技術已通過公司內部測試,公司後期將根據市場需求,申請通過中國汽車工程研究院股份有限公司檢測中心的新國標GB38031-2020測試,預計測試周期約為3個月。測試後,即可銷售使用。
