To meet the requirements of high energy density and fast charge for energy storage systems and electric vehicles,the high-energy and high-power density lithium-ion batteries have attracted numerous attentions.Designing thick-electrode can significantly increase energy density and reduce cost,and is also compatible with various electrode materials,which makes it one of hottest researches for the development of high-energy density lithium-ion batteries.Thick electrodes usually suffer from poor mechanical properties and sluggish reaction kinetics.Therefore,it is very important to construct a thick electrode with good mechanical properties and fast transport network for lithium ion and electron.The electrochemical behavior and key scientific issues of thick electrodes were firstly analyzed in this review,the current strategies for constructing thick electrodes and their advantages were then introduced,and finally the design principles and the development direction of thick electrodes were pointed out. |
