However, at high discharge rates, the utilization rate of the manganese dioxide cathode is low. For example, only 30-40% of the active material in an alkaline Zn/ MnO2 battery is utilized in a high power electronic device. 但是在大电流、高功率放电时,二氧化锰正极材料的利用率低,只有30~40%。
Within a certain range of charge and discharge rate, discharge capacity of lithium-ion battery was strong connected with discharge current rate. 一定充放电倍率范围内,锂离子电池放电比容量与放电电流设置倍率相关性较强。
Compared with graphite anodes, alloy anode materials have a high theoretical capacity and a fast charge/ discharge rate, making alloys a class of very promising high-specific energy Li-ion battery anode materials. 与商业化的碳极相比,合金负极材料具有理论容量高、快速充放电能力等优点,因而是一类非常有发展前景的高比能锂离子电池负极材料。
Due to high energy density, long cycle life, memoryless effects and low self discharge rate, the lithium ion battery becomes a most popular member of the battery family. 而锂离子电池由于能量密度高、循环寿命长、无记忆效应、自放电率低等诸多优点使其成为了二次电池的主流产品。
