Uses and functions:
The nano-silicon dioxide is added between the positive and negative electrodes, the main role is to separate the positive and negative active substances to prevent the two poles due to contact and short circuit; In addition, electrochemical reaction, to maintain the necessary electrolyte, the formation of ions Moving the channel. Diaphragm material is not conductive, the type of battery is different, the use of the diaphragm is also different. For lithium-ion batteries, because the electrolyte for the organic solvent system, the diaphragm requires the following performance.
① In the battery system, its chemical stability is good.
② Mechanical strength, long service life.
③ Organic electrolyte ionic conductivity than the aqueous solution system is low, in order to reduce the resistance, the electrode area must be as large as possible, so the diaphragm must be very thin.
④ Silicon oxide for battery separator has a good compatibility, and the battery separator slurry of a variety of solvents compatibility.
Storage:
Nano-silica should be stored in a ventilated, dry warehouse. In the transport process, to moisture, water, pressure, do not throw throwing.
