New research believes that sugar would be the solution to improve current lithium batteries by the end of the decade, which would bring combustion car autonomies to the electric world.
The great stumbling block that electric companies have when it comes to convincing potential buyers is always the same: autonomy.
Despite the great advantages that EVs (as they are known internationally) represent when used in cities and small towns, the reality of those who make long trips makes it almost impossible for a large majority to lean towards electric models.
In the best of cases, an electric car can travel between 500 and 600 km, and this distance is achieved under ideal conditions, Therefore, in the event of unforeseen events, the actual number of kilometers traveled decreases. Making it impossible to make a Madrid – Barcelona, for example, calmly.
For this reason, Battery engineers have been searching for the perfect formula for years to significantly increase the autonomy of lithium batteries. (the most common today) without increasing the cost of production.
And it seems they have found it. Researchers from Monash University (Melbourne, Australia) claim to have found the key element that will allow the technology that is called to replace batteries to function lithium ion.
The idea, for a while, was get lithium-sulfur (Li-S) batteries to replace current lithium-ion batteries, because these have a greater durability, are cheaper, have a higher loading speed and are more respectful with the environment.
And, in theory, Li-S batteries can store up to 5 times more energy than lithium ion batteries.
The problem with these batteries was its chemical instability, since once the chemical reactions that took place inside the battery began to work, they quickly destroyed it.
And the discovery comes in this sense, because researchers from Monash University claim to have discovered the chemical element that will give stability to lithium-sulfur batteries. And we all have that element at home: sugar..
According to their tests, using a glucose-based additive on the positive electrode has allowed them to stabilize the formula and, therefore, the technology itself.
Majumder, the university’s principal investigator, assumes that with the technology in these batteries, a bus or truck will be able to travel between Melbourne and Sydney (almost 900 km) without having to stop along the way to recharge the battery, as is currently the case.
