Scientists have created a new electrolyte that increases the voltage of lithium-ion batteries

Electrolyte is an essential, essential part of any battery. After all, it is through it that the charge and discharge current passes. Modern lithium-ion batteries still use an electrolyte that was developed back in the 1990s.

A research group from the University of Tokyo set itself the task of significantly improving the characteristics of the electrolyte and this is what they did.

Who and how created the new electrolyte

Work on the creation of a new electrolyte was carried out at the University of Tokyo by a research group led by Professor Atsuo Yamada.

Numerous experiments have resulted in a fluorinated cyclic phosphate solvent (TFEP) -based material.

It, in turn, greatly improves the currently widely used ethylene carbonate (EC).

As you know, the currently used EC turns out to be unstable and fire hazardous even at a voltage exceeding 4.3 Volts.

But the addition of TFEP made it possible to increase the voltage to 4.9 Volts and at the same time the battery remains stable in all respects.

What gives an increase in voltage

It would seem, well, what's wrong with that, well, they managed to raise the voltage by 0.6 volts and get a stable element.

In fact, such an increase in voltage due to just replacing the electrolyte will not allow much by changing the design of existing lithium-ion batteries, to increase their resource and operating time on one charge.

This means that a modern electric car will travel on one charge, conventionally, not 1000 km, but 1300 km. It will also increase the autonomy of all electronic gadgets in the design, which uses lithium-ion batteries.

This project is already close to commercial implementation. So it is possible that in the very near future we will be using lithium-ion batteries with increased autonomous operation.
