应中国科学院广州能源研究所集成技术中心邀请，加拿大滑铁卢大学陈璞教授将于8月31日访问广州能源所并举行学术报告会。报告安排如下：  

　　时间：2015年8月31日（星期一）上午10:00 

　　地点：生物质大楼911会议室  

　　报告人：Pu Chen 

　　报告题目：Rechargeable Hybrid Aqueous Batteries (ReHAB) 

　　报告摘要： 

　　A new aqueous rechargeable battery combining an intercalation cathode with a metal anode (the first order electrode) has been developed. The concept is demonstrated using LiMn2O4 and zinc metal electrodes in an aqueous electrolyte containing two electrochemically active ions (Li+ and Zn2+). The battery operates at about 2 V and preliminarily tests show excellent cycling performance, with about 90% initial capacity retention over 1000 charge-discharge cycles. Use of cation doped LiMn2O4 cathode further improves the cyclability of the system, which reaches about 95% capacity retention after 4000 cycles. The energy density for a prototype battery, estimated at 50-80 Wh kg-1, is comparable or superior to commercial 2 V rechargeable batteries.
