Why did Nissan say the solid-state batteries were still incomplete?

Although solid-state batteries are expected to become a breakthrough technology for electric vehicles, which Toyota and Volkswagen admire, Nissan is not optimistic about the battery's potential, according to Auto News on April 2.

Nissan's senior technology director said solid state batteries were near zero development and faced many obstacles before supplying power to electric vehicles. It also means that Nissan is not developing solid-state battery technology as Toyota and Volkswagen are. The three companies are speeding up production of electric cars.

Takao Asami, senior vice president of research and advanced engineering at Nissan, said that solid state battery technology was not perfect enough to be used in electric cars before 2025. Obstacles include costs and production difficulties. All solid-state batteries are basically still in the initial research stage, so its development prospects are now almost zero.

Solid substances in solid batteries can replace liquid electrolytes in lithium-ion batteries, thereby increasing energy density, reducing weight, improving safety, and shortening charging times. Asami said that while solid-state batteries do work in the laboratory, if you make them larger and put them in cars, there is still no guarantee of mileage, safety and cost. He said more breakthroughs were needed.
