New more safer flexible lithium-ion batteries developed

Technology is becoming smart and safer day-by-day, now scientist developed a new type of flexible lithium-ion batteries which are less hazardous.

What are lithium-ion batteries?

lithium-ion battery or Li-ion battery(abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

Low-quality lithium-ion batteries, contain highly flammable, toxic, and moisture-sensitive electrolytes that make them prone to spontaneous explosions.
Scientists at the Johns Hopkins University, University of Maryland and the Army Research Laboratory in the US developed a new type of flexible lithium-ion battery build by highly-concentrated water-based electrolyte called “water-in- salt”.

The team operated their flexible lithium-ion battery in open air with minimal packaging, using only some electronically insulating, heat-resistant tape to keep it in place. In their demonstration, the battery powered a significant motor load without any safety concerns. 

“We want to increase the robustness of the electrolyte and the energy density of the batteries even further,” Gerasopoulos said. “This work though proves the concept that we can build safe lithium-ion batteries that can survive mechanical abuse,” he said.
