Research and develop explosion-proof batteries

The battery is always hidden risk of explosion, danger to users. To overcome this problem, scientists are now working to produce safe, fire-proof batteries.

Batteries that burn and explode pose a potential danger to users, destroy expensive equipment, and even cause fires and cause serious accidents. Major technology companies have to recall products even though there is only a small battery error, which is enough to see the danger of potentially explosive batteries.

While the technology of battery density and capacity is leveling off, there is no optimal solution to solve the problem of the small amount of battery capacity of the devices, the scientists have changed direction, that is to find ways to to provide safer, fire-resistant, high temperature resistant batteries.

Lithium-ion battery technology has traditionally been widely used and undeniably the advantage it brings, but at the same time, the danger of fire is inevitable. The Semiconductor Energy Laboratory (SEL) research lab has studied the new Li-ion battery technology, allowing these batteries to operate under high temperatures without the occurrence of explosions, they tested them. battery and indicate the maximum temperature can withstand up to 300 degrees C.

The secret is that using a special electrolyte ion solution as a solvent, the ion electrolyte is the substance produced when heated to the melting point of salt, for example NaCl, this ion solution will close The role is to stabilize the temperature and keep everything working normally when the temperature is high, but adding ion electrolyte components can reduce the performance of the battery. Scientists handle the problem by replacing lithium with magnesium, applying dual carbon battery technology that does not generate heat on its own, which means the battery may be burnt by external impact, but never Fire.

The work is still in the research and completion stage, however, in the future, consumers will have the opportunity to use safer, fire-proof and more battery products with more features and applications. use in life.
