Researchers at the Samsung Advance Institute of Technology (SAIT), in collaboration with its R&D center Samsung in Japan, seems to have figured out how to create batteries solid state batteries, which are very likely to replace conventional lithium-ion batteries in the near future.
As experts point out, this change will take time and it is not expected to launch such batteries earlier than 2024. However, companies prefer them because of their advantages over common lithium-ion batteries and long working life. this project. But it is not over yet and it will take some time before they are released.
Samsung solid state battery
Samsung, on the other hand, made it possible through extensive research and advanced engineering. The researchers Samsung used a very thin (5 micrometer) layer of silver carbon on the battery's rise, which prevents the formation of dendrites.
Along with other technologies used, the new battery it has twice the energy density of existing lithium-ion and has a range of 800 kilometers. It can be charged up to 1000 times, offering up to 800.000 kilometers of drive in electric cars.
As they have a higher power density, these batteries will be smaller in size. This means that there will be more free space on electric vehicles to be used for a variety of other purposes.
Unlike lithium-ion batteries that lead to the formation of dendrites at rapid charge due to the liquid electrolyte, which can eventually lead to ignition, solid batteries do not form dendrites.
According to John B Goodenough, who works on solid-state batteries and is the man behind the success of lithium-ion batteries, solid batteries have 2,2 to 5 times the energy density of lithium-ion batteries .
They can carry up to 1200 cycles loading without undergoing a major degradation of their cells. Instead, lithium-ion batteries will suffer the same degradation in just 500 charges.
Solid-state batteries can operate at temperatures from -20 to 60 degrees Celsius.
So these are longer lasting batteries that offer longer safety and have a higher energy density than lithium-ion.
Also, as Mr Goodenough says, these batteries can be made from environmentally friendly materials at a lower cost. However, so far companies have spent large amounts of money on making such batteries. Only Samsung has so far managed to create a functional package, but it's expected to be expensive.
Nevertheless, as long as this technology continues to evolve, it is very likely that in the future we will have an affordable and optimized battery.
