Iranian Scientists Produce Flame Retardant Batteries

“In lead-acid batteries, the charging and discharging process produces hydrogen gas in the battery. An increase in the pressure inside the battery causes an explosion and even the electricity produced in the battery can cause it to catch fire. As a result, the air inside the battery needs ventilation,” Saeed Zokayee, the managing director of the knowledge-based company.

“If the air flows freely inside the battery and outside, flame and dust can infiltrate into the battery and its acid comes out. As a result, the ventilation system should allow air to enter and exit and prevent dust and liquids from entering and exiting,” he added.

Noting that due to its material and porosity, the battery flame retardant tablet prevents the passage of liquids and causes the produced gas to escape from the battery, Zokayee said, “Due to the high chemical resistance of the materials used in the battery, it resists a long time against the acid and performs well.”

In a relevant development in July, Iranian scientist Mohamad Khoshkalam from the Technical University of Denmark had also used new electrolytes found in rocks to make batteries.

Researchers have discovered a new material based on rock silicates that could replace lithium in electric car batteries in the future.

This material can help develop new types of energy storage devices that can be more cost-effective and insensitive to moisture.

According to the researchers, these rock silicates can be found in ordinary rocks that are abundant everywhere.

Potassium‐ion batteries (KIBs) are considered as the potential energy storage devices due to the abundant reserves and low cost of potassium. In the past decade, research on KIBs has generally focused on electrode materials

Iranian scientist Mohammad Khoshkalam, a researcher at the Technical University of Denmark realized that materials based on rock silicates can be suitable for a solid state electrolyte.

“The potential of potassium silicate as a solid state electrolyte has long been discovered, but in my opinion has been overlooked due to challenges with the weight and size of the potassium ions. Because these ions are large and therefore move at a slow pace,” the Iranian scientist said.

Khoshkalam discovered a way that enables ions to move faster in rock silicates than in lithium-based electrolytes.

“The first test with a battery component showed that this material has very good conductivity as a solid state electrolyte. I cannot reveal how the ingredients were developed, because the recipe and method are now patented,” the researcher said.
