Researchers at the Samsung Institute of Advanced Technology (SAIT), in collaboration with Samsung's R&D center in Japan, have found their way to a viable solid-state battery. These solid-state batteries could replace conventional lithium-ion batteries for the foreseeable future.
However, experts believe that it will not be a quick process and that it will take time, perhaps by the end of 2024. Solid-state batteries have always been on the minds of many large companies due to their advantages over lithium-ion batteries. . Many companies are already working on it. However, it is still an incomplete task to produce and market these batteries.
Samsung Solid State Battery
Samsung, on the other hand, made this possible through their extensive research and brilliant engineering. The Samsung researchers used a very thin layer (5 micrometers) of silvery carbon on the anode of the batteries, which prevented the formation of dendrites.
Combined with other technologies, this battery cell has around twice the energy density of lithium-ion batteries and a range of up to 800 km. Also, it can be charged about 1000 times. With this, it can provide around 800,000 total miles for electric vehicles.
Given the fact that it has a higher energy density than the lithium-ion battery, they will be compact batteries. With this, there will be additional space in electric vehicles that could be used for various purposes.
What Samsung has achieved is like the tip of the iceberg, considering the potential of solid-state batteries. According to the experts, can revolutionize the future of batteries, both for electric cars and mobile phones.
Why Solid State Batteries May Be Revolutionary
- Unlike lithium-ion batteries that lead to dendrite formation on fast charging, which can eventually lead to fire, solid-state batteries do not form dendrites. Dendrites are usually formed due to the liquid electrolyte; however, solid state batteries have solid electrolytes.
- According to John B Goodenough, who is now working on solid-state batteries and also the man behind the success of lithium-ion batteries, he said that solid-state batteries have 2.2 to 5 times the energy density of conventional batteries. lithium ion
- It can have up to 1200 charge cycles with low cell degradation. Unlike solid state batteries, lithium ion batteries will suffer the same degradation in 500 charges only.
- Solid state batteries can work within temperature ranges from -20 degrees Celsius to 60 degrees Celsius
- In short, these are higher energy density, longer lasting and safer batteries compared to lithium ion cells.
Also, according to Mr. Goodenough, these can be made from earth-friendly materials that can reduce the cost of batteries. However, nowadays companies spend a considerable amount of money to develop these batteries. Until now, only Samsung has managed to build a viable battery, which, on the other hand, will be expensive.
However, with the technology and research going on today, an affordable cost-optimized solid-state battery is not far on the horizon.
