Benefits of technology

This invention relates to modifying polymers with special properties that improve their ability to conduct electricity or transfer thermal energy efficiently while also preventing damage caused by environmental factors such as water vapor. These modifications can be applied during production processes without affecting its quality or functionality.

Problems solved by technology

This patented technical problem addressed in this patents relates to how to prevent damage from overheating batteries caused by excessive temperatures that can lead to fire hazards due to rapid buildup within them when they get too hot again after being charged with an empty state (when there're no charge).
