Lithium-ion secondary battery without internal short |
| abstract |
The present invention provides a lithium ion secondary cell characterized in that a compound containing at least one intramolecular thiol (-SH) group is provided in a unit cell of a battery. In the present invention, by using a thiol group-containing compound having excellent reactivity with copper or copper ion, it is possible to form a dendrite by reducing on the surface of a negative electrode the copper ions which are present inside the battery or during the operation of the battery, It is possible to prevent the internal short-circuit between the electrodes due to the short-circuit. |
