2,4-DIFLUOROBIPHENYL - Reference Information
| LogP | 2.673 |
| overview | 2,4-difluorobiphenyl is not only an important intermediate in the synthesis of fluorobenzene salicylic acid, but also the key to the synthesis of fluorobenzene salicylic acid. it can also be used as an anti-overcharge additive for battery electrolyte. its purity is the key to determine the anti-overcharge and performance of the battery. Lithium batteries include positive electrode, negative electrode, electrolyte and separator. However, during the charging and discharging process of the battery, heat will be released, resulting in a decrease in battery performance. At the same time, there is also a phenomenon of battery overcharge, which restricts the development of lithium ion batteries and electronic information industry. The existing method is to add battery additives to prevent the hazards and disadvantages caused by battery overcharge. 2, 4-difluorobiphenyl is this anti-overcharge additive. |
