Researchers at Samsung Advance Institute Of Technology (SAIT), in collaboration with the R&D center of Samsung in Japan, have found their way to feasible Solid-State Battery. These solid-state batteries could replace the conventional Li-ion batteries in the foreseeable future.
However, experts believe that it will not be a fast process, and it will take its time, maybe by the end of 2024. Solid-State batteries have always been in the minds of many big companies because of their advantages over Li-ion batteries. Many companies are already working on it. However, it remains an incomplete task to produce and commercialize these batteries.
Samsung Solid-State Battery
Samsung, on the other hand, made this possible through their extensive research and brilliant engineering. Researchers at Samsung used a very thin (5 micrometer) layer of silver carbon at the anode of batteries, which prevented the formation of dendrites.
Combined with other technologies, this battery cell has around two times of energy density than Li-ion batteries and a range up to 800km of range. Also, it can be charged around 1000 times. With this, it can provide around 800,000 km of total running miles for electric vehicles.
Given the fact that it has higher energy density than Li-ion battery, these will be compact batteries. With this, there will be extra space in EVs that could be utilized for various purposes.
What Samsung has achieved is like a tip of the iceberg, considering the potential of Solid-State Batteries. According to the experts, it can revolutionize the future of batteries.
Why Solid-State Batteries Can Be Revolutionary?
- Unlike Li-ion batteries that lead to the formation of dendrite on fast charging, which can eventually lead to fire, solid-state batteries do not form dendrites. Dendrites are usually formed because of the liquid electrolyte; however, solid-state batteries have solid electrolytes
- According to John B Goodenough, who is now working on solid-state batteries also the man behind the success of Li-ion batteries, said that solid-state batteries have 2.2 to 5 times the energy density than Li-ion batteries
- It can have up to 1200 charge cycles with low cell degradation. In contrast to the solid-state batteries, Li-ion batteries will go the same battery degradation in 500 charges only
- Solid-State batteries can work within temperature ranges of -20 degrees Celsius to 60 degrees celsius
- In short, these are longer-lasting, safer, high energy density batteries as compared to Li-ion cells
Also, according to Mr. Goodenough, these can be made with earth-friendly materials that can lower the cost of batteries. However, companies nowadays are spending a considerable amount of money on developing these batteries. So far, only Samsung has managed to build a workable battery pack, which is, on the other hand, will be expensive.
Nevertheless, with the technology and research going on nowadays, an optimized solid-state battery with affordable cost is not far away in the future.
