Scientists created battery batteries using salted electrolyte, not toxic

[ad_1]

The effects of lithium batteries are often overlooked because they explode. And let this happen too often. But knowing about that bomb in the pocket, at work or in the garage is a pleasure. Scientists have worked on nonflammable lithium batteries for decades. Perhaps that would help the new research done by scientists at Stanford.

Scientists have done an active task to maintain battery power when it is heated – like it is in the article in the journal Matter. They switched on two paths: replaced the electrolyte solution with more organic solvents and increased the concentration of lithium salts in the electrolyte, which also reduced the flammability of the solution.

In conventional lithium-containing batteries, the electrolyte vapor begins to evaporate when the cell is heated to about 60 C. The liquid is then transported into the gas phase, and the battery is inflated until the shell is destroyed and ignited. The scientists are able to choose a polymer that maintains high-dose lithium ions, and then distributes chemistry into a solvent. However, the conductivity of lithium ions in the polymer solvent was still better than when the process of using an organic solvent, and it was resolved differently.

Lilyse salts usually dissolve in lithium battery electrolyte at a rate less than one to two (not like 50% by weight). For the decrease in lithium ions’s mobility in polymer solvent, the scientists began to make salts harder, further increase their concentrations. It turns out the composition with 63 o’clock salts had the most concentration. Molecules in this composition are well absorbed from each other and this prevented evaporation during the heating. The found composition with high concentration of lithium salts easily withstood heating up to 100 C. The electrolyte allowed the battery to remain alive even at this temperature and not ignited.

The study’s author claims this new battery electrolyte is very interesting. The lithium-ion battery will have a huge impact on the consumer electronics and the electric car, said one of the authors.
