BYD has announced that it is developing solid-state batteries that will be launched initially in 2027, before mass adoption starting in 2030.
The announcement came during an event held in China, through BYD’s battery division technology director, Sun Huajun, who revealed that batteries with sulfide-based electrolytes will achieve over 500 Wh/kg of energy density, promising remarkable performance in terms of range and charging speed.
It is worth noting that solid-state batteries, also known as solid electrolyte batteries, offer several advantages over conventional lithium-ion batteries, being considered safer and having higher energy density, allowing for faster charging than traditional batteries. Additionally, the lifespan of solid-state batteries tends to be longer, making them attractive for the automotive industry, especially for the high-performance electric vehicle segment.
However, the arrival of solid-state batteries on the market will not put an end to lithium iron phosphate (LFP) batteries, as BYD’s head and engineer, Lian Yubo, made it clear that the well-known LFP batteries will continue to exist for the next 15 to 20 years, as this type of battery will remain important for affordable 100% electric models.
Remember that BYD is not alone in the transition to more advanced battery technology, as companies like Toyota, Honda, and Nissan are also investing in the production of solid-state batteries. However, BYD seems to stand out from its Japanese rivals, promising the use of solid-state batteries sooner than its competitors.
