Q&A

1-What is ceramic aerogel?

Ceramic aerogel is an advanced insulation material made with ceramic oxides, offering ultra-low thermal conductivity under high-temperature. 

2-How high a temperature can ceramic aerogel withstand?

It can operate reliably above 1200 °C, with some formulations stable up to 1350 °C.

3-Can ceramic aerogel stop thermal runaway in lithium-ion batteries?

It provides effective fire barriers and thermal runaway protection in the 700–1000 °C range, outperforming silica aerogels.

4-What is the thermal conductivity of AEG ceramic aerogel?

0.021–0.025 W/m·K at room temperature (25℃), 

0.038-0.060 W/m·K at 500℃

5- Is ceramic aerogel flexible or rigid?

it is soft, cuttable, and easy to integrate with mica/ pet sheet

6-Can ceramic aerogel be laminated with other materials?

Yes, it can be packaged with PET, mica, or aluminum foil, and customized with adhesive backing or protective strips.

7-What thicknesses are available?

Typically 1–10 mm

8-Is ceramic aerogel safe and environmentally friendly?

It is inorganic, non-toxic, non-flammable, and manufactured using eco-friendly processes.

9-How does it compare in price to aerogel?

The price is cheaper, because it is developed with a proprietary full-gradation composite formulation and in-situ aerogel generation technology, no need to pay the patent cost of ASPEN.

10-How easy is it to integrate ceramic aerogel into battery modules?

It can be cut to size, applied with double-sided adhesive, and packaged for plug-and-play integration.

11- Is ceramic aerogel durable under thermal cycling?

Yes, it remains stable under repeated heating (above 1000c) and cooling, ensuring long-term reliability.
