摘要
Abstract
Lithium-ion battery has become the most popular battery in aviation,aerospace,and equipment applications because of its high energy density,long cycle life,and no memory effect.Fast-charged lithium-ion battery refers to the lithium-ion battery with a large rate of charging capacity.Ordinary lithium-ion batteries mainly have low charging rates.At the rate of 1 C,a battery takes 1 h to 1.5 h to be fully charged.After the fast-charged lithium-ion battery technology is adopted,the charging time can be greatly shortened.For example,at the rate of 3 C,the charging time can be reduced to about 30min.In the military field,increasing the charging rate can shorten the response time of various loads,and thus improve their flexibility and real-time performance.In this paper,the mechanism of fast-charged lithium-ion battery is analyzed.A 1.0 Ah fast-charged lithium-ion battery is prepared through the power-type design process,taking the ratio-type ternary material Ni-Co-Mn(NCM)as the cathode and amorphous-coated graphite as the anode.The battery has the specific energy up to 205 Wh/kg,and can constantly be charged and discharged at a rate of 5 C.At the rate of 3 C,the capacity retention of the battery is greater than 80%after 1 000 fast-charged and discharged cycles,demonstrating good fast-charged capability and cycle stability.关键词
