Samsung managed to make 800 km range solid state battery

Batteries that power our smartphones, laptops, electric cars and many other electronic gadgets are trying to go a step further by big technology companies. Here, Samsung was the first company to take a big step on this road.


Samsung Advance Institute of Technology (SAIM) researchers, collaborating with Samsung's R&D team in Japan , have found a way to develop viable solid state batteries. These solid state batteries will replace traditional Li-ion batteries in the foreseeable future.


However, according to researchers' estimates, this will not happen any time soon. Experts' predictions mark the end of 2024. Large technology companies have been working on solid state batteries that have great advantages over Li-ion batteries for many years, but it is a bit difficult to manufacture and commercialize these batteries.

One of the first companies to take a big step in this path, Samsung has accomplished this with its research and engineering team. Samsung researchers used a 5 micrometer thick silver carbon layer on the anode (positive end) part of the battery. In this way, dendrite formation was prevented.


When combined with other technologies, these battery cells have twice the energy density compared to Li-ion batteries and can reach a range of 800 km in electric vehicles. In addition, these batteries can be recharged approximately 1,000 times, which means that 800,000 km range can be reached for electric vehicles .


Solid state batteries have higher energy density than traditional Li-ion batteries, meaning more compact batteries. In this way, this gap, which will be formed in electric vehicles, can be used for different purposes.


What are the things that can make solid state batteries revolutionary?


  • Unlike Li-ion batteries that cause dendrite formation, dendrite does not occur in solid state batteries. Dendrites are caused by liquid electrolytes. However, solid electrolytes are used in solid state batteries .

  • John B. Goodenough, who is the name behind the success of Li-ion batteries and also works on solid-state batteries, says 2.2-5 times more density than solid-state batteries .

  • With very few cell decreases, it can be recharged over 1,200 times. In Li-ion batteries, it can only be charged 500 times with the same decrease .

  • Solid state batteries can operate at temperatures between -20 degrees and 60 degrees .


Also, according to Goodenough, these batteries can also be made with environmentally friendly materials, which is a factor that can reduce battery costs . However, companies spend significant amounts to develop these batteries, which is Samsung, the first company to produce this type of battery. Therefore, it should be noted that these batteries will be quite expensive at first.
