Abstract

The present application provides an organic-inorganic hybrid complex which can be used in a coating of a separator for a secondary battery, wherein the organic-inorganic hybrid complex is formed from basic units represented by formula (I) being periodically assembled in at least one spatial direction: [L][MC].A(I), wherein a defect percentage expressed in i/x*100% is 1% to 30%. The present application further provides a coating composition comprising the organic-inorganic hybrid complex, a coating formed from the coating composition, a separator comprising the coating for a secondary battery, a secondary battery comprising the separator, a battery module, a battery pack and a device. By applying the organic-inorganic hybrid complex of the present application in a coating, the electrolyte infiltration of a separator for a secondary battery is improved while increasing the electrolyte retention rate, thereby improving the rate capability and cycling life of the secondary battery.
