| titleOfInvention | Secondary battery |
| abstract | Provided is a secondary battery. The secondary battery of the present invention comprises an auxiliary (a compound as represented by Formula 1). Due to a small molecular weight and a short polymer chain segment, the auxiliary (the compound as represented by Formula 1) can be fully mixed with other components in the secondary battery; in addition, the auxiliary (the compound as represented by Formula 1) is in a viscous liquid, semi-solid or solid state at room temperature and therefore can fully come into contact with each component and infiltrate internal pores. The auxiliary of the present invention can form a film on a surface of a positive/negative electrode and can effectively improve the increase of internal resistance during positive electrode and negative electrode cycling, thereby prolonging the cycle life. The auxiliary of the present invention can also be involved in a film formation reaction on positive and negative electrodes to form a solid-state interfacial film structure with a certain molecular weight on surfaces of the positive and negative electrodes, such that the composition of the solid-state interfacial film on the surfaces of the positive and negative electrodes can be improved, the content of polymer components in the solid-state interfacial film is increased, the conduction of electrons and lithium ions inside electrode pieces of the secondary battery is promoted, and the dynamics of lithium ions inside the electrode pieces and the cycling performance of the battery are improved. |
