Diatomaceous Earth CAS 68855‑54‑9 is flux‑calcined diatomite powder with high‑purity silica composition. Featuring excellent thermal stability, controllable particle size and narrow particle distribution, it works as inorganic functional filler for lithium battery separator coating. When coated on polyolefin separator surface, it forms heat‑resistant protective layer, suppresses separator thermal shrinkage under high‑temperature conditions, short‑circuit risk is reduced, lifting overall safety p

Product Detail

Overview

Our Diatomaceous Earth CAS 68855‑54‑9 is manufactured by flux calcination, high‑efficiency purification and precise particle classification. Low impurity, stable chemical property and heat‑resistant performance make it suitable for lithium‑ion battery separator ceramic coating process. It can be compounded with binder and solvent to prepare coating slurry, evenly coated onto PE / PP separator substrate, building rigid heat‑stable barrier layer for battery cells.

Key Features

Outstanding high‑temperature thermal stability, effectively inhibit separator thermal shrinkage at elevated temperature.
Strictly controlled particle size and narrow particle distribution, facilitate thin and uniform coating layer.
Low heavy‑metal and soluble impurity content, avoid side reaction inside lithium‑ion battery cell.
Good slurry dispersion performance, less agglomeration during slurry mixing and coating procedure.
Chemically inert, compatible with electrolyte, no adverse reaction inside battery system.
Improve separator puncture resistance, enhance cell safety against thermal runaway risk.

Main Applications

Ceramic coating filler for lithium‑ion battery PE, PP base separator
Power battery separator modification
Consumer lithium‑ion cell separator coating material
Energy‑storage lithium battery separator functional coating formulation

Usage Recommendation

Match particle size grade according to target coating thickness of separator.
Fully disperse in solvent together with binder to prepare homogeneous coating slurry.
Control slurry viscosity and solid content to guarantee coating uniformity.
Strictly control raw material moisture; high moisture will harm battery electrochemical performance.
Cooperate with existing ceramic coating process parameters for trial verification before mass production.

Storage & Package

Store in dry, constant‑temperature and dust‑proof warehouse, keep bags hermetically sealed against moisture.
Standard package: 25kg aluminium foil lined moisture‑proof woven bag.

Note: Battery‑grade material requires strict incoming inspection on impurity, moisture and particle size before mass application. Pilot test is strongly recommended.
