摘要
水系锂离子电池具有能量密度高、无毒、安全性高、成本低等优点,在智能电网等储能电池方面具有很好的应用前景。本文以制备的锰酸锂材料为正极,设计组装水系锂离子电池,详细探讨了不同集流体、不同充放电截止电压等装配工艺对电化学性能的影响。结果表明,不锈钢网SS304更适合作为水系锂离子电池的集流体,在1.50~2.15V电压范围内展现出了优异的电化学性能。
Aqueous lithium-ion battery has the advantages of high energy density,non-toxic,high safety and low cost. It has a good application prospect in intelligent power grid and other energy storage batteries. In this paper,new aqueous lithium-ion batteries are assembled using the prepared lithium manganate as cathode materials. The effects of assembly processes such as different current collector and different cut-off voltages on electrochemical properties are discussed in detail. The results show that using stainless steel SS304 as current collector,the aqueous lithium-ion battery exhibits superior electrochemical Properties at 1.50~2.15 V.
