SIO2 %: 30 Na2O %:0.05 PH value: 2.0-4.0 Viscosity at 20 degree: 3.5-4.5 SP.GR at 20degree: 1.19-1.21 Particle Size(nm):10-20 Used in battery, short service life of ordinary lead-acid batteries, use silicon sol can be configured to solid electrolyte battery, greatly improving the service life of the battery;At the same time, ordinary sulphuric acid electrolyte, in the car to overflow, but the use of solid state electrolyte battery has very good solve the problem, effectively prevent the leakage and overflow of sulfuric acid to avoid pollution of the environment.
