Solid-state batteries are the necessary revolution to achieve better performance.
One of the challenges facing the automotive sector is to completely change the business model. From the European Union, the date for the end of the combustion engine will be in 2035. The impulse of the electric car goes through improving its autonomy and the new generation of solid state batteries. In this article we are going to see why this technology can be the key to giving the electric car the definitive boost.
A step forward in autonomy and reliability
electric vehicle batteries
The first electric cars were greatly penalized by the weight of the batteries and their autonomy. At present, this handicap has been reduced, but the batteries that power electric cars are still limited. The lack of a consistent network of charging points, although this problem is becoming less and less frequent, means that many are hesitant to decide when it comes to purchasing an electric vehicle. And it is that, like everything else, electric cars have many advantages, but also some drawbacks.
Any battery, whether it’s a car battery, a cell phone battery, or the batteries in your radio, work for the transfer of electrons that occurs through a liquid called an electrolyte. The main problem with this type of battery is that the different charge and discharge cycles cause the latter to increase its density, even solidifying.
This leads to the fact that, progressively, it does not offer the same performance and that the battery or the battery ends up dying of exhaustion. You will have verified it when you have forgotten the batteries in a device for a long time, the electrolyte has come out in a process called sulfation.
Solid-state batteries would dispense with liquid electrolytes, being replaced by a solid. This could be anything from gold to crystal, but the advance would be quite important and would have a direct reward in all areas, but especially in the electric car. This type of vehicle is generating more and more interest, and brands like Xiaomi have already set to work to develop their first model.

Advantages of solid state batteries
The main advantage of this type of battery is that its capacity is much higher. There is even talk that they could provide 1000 Wh/litre. Namely, they would accumulate more energy and reduce their size. This would lead to solid-state car batteries being much less bulky and heavy than current lithium-ion batteries. The consequence would be clear, to reduce the final weight of electric vehicles, which, today, is their main problem. On the other hand, reducing weight leads to increased autonomy.
Solid-state batteries, in addition to a reduced volume and weight, will have greater resistance to wear. But perhaps one of the most interesting issues for the consumer is that they will be cheaper to manufacture. Initially, the price is estimated to be 40% lower. When solid-state battery factories operate at full capacity, the savings could be up to 70%. An important stimulus that would help achieve the objective set by the European Union and finish popularizing the electric car.
This technology is already produced on a small scale and there are quite a few firms, especially those in the automotive industry, that are interested in developing it in order to implement it in their vehicles. Solid-state batteries also face a number of challenges to overcome. But there is no doubt that The seed has been planted to ensure that, in the case of electric vehicles, these batteries give the best of themselves. In this way, a greater effectiveness would be achieved, an increase in performance and, therefore, in autonomy.
This would prevent the feeling that some owners have known as autonomy angst. That feeling of being stranded anywhere without a recharging point very close. Solid state batteries are the necessary turning point for the electric car to finish taking off.
