Benefits of technology

This technology helps prevent damage caused by high temperatures during manufacturing processes for electricity storage devices such as tantalum or lithium batteries that use an insulating material called ceramic foil (cerarn). It works well with both metallized plastic materials like polyethylene terephthlate) used for these components while still maintain their strength at elevated temperature levels.

Problems solved by technology

Technological Problem: The technical problem addressed in this patented text relates to improving the performance of electricity storage devices such as lithium ion batteries due to improved thermal stability while reducing its overall dimensions without increasing weight or requiring more space than necessary.
