2,4-Difluorobiphenyl CAS 37847-52-2 Purity >97.0% (GC) Battery Additive

2,4-Difluorobiphenyl (CAS: 37847-52-2) is not only an important intermediate in the synthesis of fluorobenzene salicylic acid, but also can be used as an overcharge prevention additive in battery electrolyte, its purity is the key to determine the battery overcharge prevention and performance. Lithium battery includes positive electrode, negative electrode, electrolyte and diaphragm, but in the charging and discharging process, will release heat, resulting in battery performance degradation, and there is also the phenomenon of overcharging battery, lithium ion battery and the development of electronic information industry constraints. The existing way is to add battery additives to prevent the harm and disadvantages caused by overcharge of the battery. 2,4-Difluorobiphenyl is one such anti-overcharging additive.
