英文摘要Lithium-ion batteries (LIBs) are playing an increasingly pivotal role in nowadays clean energy society. Similar to the fatigue behavior of solids and structures, the performance of LIBs also degrades under repeated usage, exhibiting a capacity decay during cyclic service. Battery fatigue seriously threats safety operation of the energy- using system, demanding a profound understanding on the cycle-life of LIBs. In order to quantify fatigue damage in LIBs, we construct an empirical fatigue map based on large-scale experiments at various constant charging and discharging rates. In combination with the empirical relationship between charging-rate C, discharging-rate D, and resultant cycle-life N, we formulate a damage function fi due to any cycling number ni at a constant charging- rate Ci and discharging-rate Di: fi = ni/Ni, where Ni is the cylcle-life of the battery at Ci and Di. The damage f in batteries under dynamic cycling profiles is assumed to be linear accumulated and follows the Palmgren-Miner rule, f = & sum; ifi. A failure state, with f = 1, can be conveniently assessed for batteries subjected to arbitrary dynamics cycling profiles. Experimental validation of the fatigue map and damage function exhibits a mean percentage of no more than 7.0 % and 2.1 %, respectively. The method reported here enables us to extend safety analysis from material scale to battery scale, and is therefore meaningful for cycle-life evaluation of LIBs, as desired in energy storage systems consisting of many cells.
