초록

Lithium-ion batteries are currently widely used secondary batteries, but as the use environment becomes harsher and larger, there is a problem in stability, and it is believed that the possibility of developing energy density is limited. Therefore, there is a need for an all-solid-state battery that can solve this problem by replacing the conventional liquid electrolyte to the solid-state electrolyte. In particular, the polymer-based solid electrolyte has been treated as the promising candidate for all-solid-state batteries due to the excellent mechanical properties and inexpensive fabrication process. However, overcoming low ion conductivity is an inevitable issue for enabling the practical application of polymer-based electrolyte. To compensate the limitation of ion conduction in polymer layers, the strategies of introducing the additives in polymers have been suggested through the hybridization and functionalization of polymers for enhancing the ion transportation. In this review, the recent research progress of various type of additives for polymer electrolyte is presented and the active/passive/polymer type additives are studied to obtain the design principle dealing with the improvement of ionic conductivity and properties of polymer solid electrolytes.
