The Application of 3D Printing in Lithium-ion Batteries

Abstract

Three-dimensional printing (3DP) has drawn a lot of attention in recent years. With the rapid advancement of 3DP, its application has evolved from mechanical structural components to functional devices. Lithium-ion battery is one of the most important energy storage devices which has tremendous impact on modern society. However, current lithium-ion battery technologies are facing great challenges from the emerging applications. The application of 3DP in lithium-ion battery may provide a new technology solution. The present paper started with the current structure and manufacturing technology of conventional lithium-ion battery and its disadvantages in fulfilling emerging applications was discussed. Afterwards, 3D lithium-ion battery was proposed and its advantages were discussed. The progress on the application of 3DP in 3D lithium-ion batteries is given and the future development of 3D-printed lithium on batteries were discussed.
