Electric vehicle batteries are entering a new phase with an important development in technological features to be presented at the “SNE Battery Day 2024” exhibition in Seoul, South Korea.
Samsung’s new solid state battery for electric vehicles promises to rewrite the rules of electric mobility, although it will take time and a lot of testing before any definite conclusions can be drawn.
The tech giant has revealed that its pilot production line for solid state batteries for electric cars is now fully operational.
Initial batches of the battery have already been delivered to electric car manufacturers for evaluation.
We have delivered samples to customers from the end of last year to the beginning of this year and we are getting positive feedback,
said Samsung SDI.
The new batteries are capable of offering a range of 1,000 kilometers, charging in just 9 minutes, and will have a lifespan of 20 years. Compared to today’s lithium-ion batteries, Samsung SDI’s solid state batteries are smaller, lighter and safer.
The solid-state battery technology boasts an impressive energy density of 500 Wh/kg, almost double the 270 Wh/kg density of conventional EV batteries. This increased density could potentially double the driving range of today’s electric vehicles.
However, due to their high production costs, the initial application of these batteries will be limited to the category of ultra-luxury electric vehicles.
At the same time, Samsung is also developing more affordable cobalt-free lithium iron phosphate (LFP) batteries. He estimates that mass production of solid-state batteries will be possible by 2027.
While progress in the field of solid-state batteries is significant, the Korean company has to navigate a competitive environment dominated by Chinese manufacturers. The limited availability of high-speed charging infrastructure remains a notable challenge, with some Chinese battery manufacturers already offering 5C or 6C charging speeds, corresponding to 480kW or even 600kW charging stations.
