SES is developing a new salt-based battery for electric cars, which, in addition to doubling the autonomy of electric vehicles, manages to be safer than lithium-ion batteries
Electric cars are already impressive for offering incredible autonomies, as is the case with the new Tesla Model S Plaid Plus, which manages to offer 836 km with just a single charge. However, SES announced the creation of an even more promising salt-based battery solution for electric cars that promises to offer up to twice the autonomy with a component with a volume equal to or even smaller than the traditional ones.

Learn how the new salt-based battery for electric cars works
The new technology from SES, which can double the autonomy of electric vehicles, still uses lithium ion cells, however without the graphite in the anode, which is responsible for capturing the lithium ions during battery charging.
Graphite was replaced by pure metal lithium anode, which needs less space and manages to offer electric cars better autonomy. One issue was to prevent debris from building up, so the company took a hybrid approach by coating the anode with a proprietary compound plus a liquid electrolyte saturated with a form of salt to ensure battery safety in electric cars.

According to SES CEO Qichao Hu, this new salt-based liquid is very stable in a lithium metal, very safe, non-volatile and non-flammable, and also non-organic.
SES uses AI system to detect faults in electric car batteries
To ensure the safety of the salt-based battery, an assessor pierced the component with a nail and it did not catch fire, something impossible to do with a conventional lithium-ion battery. Therefore, the system can use forms of automatic repair with a suitable charger or even recommend changing the battery before an accident occurs.
In addition, the company also points out that it currently uses a system with artificial intelligence to identify possible failures and defects in its components and plans to implement this system in electric cars. For now, the company is in business with automakers such as GM, Geely, Hyundai, SAIC and Foxconn to bring its new technology to electric cars.
The company's CEO claims that the prototypes should be completely optimized to be used by the end of next year. An SES factory is still being implemented in Shanghai and is expected to be completed around 2023. The first electric cars with the new salt-based batteries are expected to hit the market in 2025.
solid state batteries
Solid-state batteries, which have been awaited by the industry for some time, are starting to crawl in testing. Solid Power, formed by Ford and BMW, set the start of the first test production of the new component for 2022.
Solid-state batteries have gained prominence and are being seen as the future for hybrid and electric cars. Although their production is a little difficult, the technology offers a higher energy density, has a longer useful life and still reduces production costs.
