CTOnews.com, October 29 (Xinhua) Nissan attracted people's attention with four electric concept cars and bold new design language at the Tokyo Motor Show (Japan Mobility Show) in Tokyo, Japan. However, the real disruptor may be the all-solid-state battery (ASSB) technology that Nissan is developing. Kazuhiro Doi, vice president of Nissan's research department, introduced the emerging battery technology at the scene, which could make a qualitative leap forward for Nissan's next generation of electric vehicles.

ASSB technology allows electric vehicle batteries to have "almost twice the energy density of existing batteries", faster charging performance and lower cost, according to Kazuhiro Tsui. This higher energy density provides more options for Nissan's product planners and engineers, and applies to "all types of cars," he said.

The use of each battery unit can provide more energy, allowing large, heavy-duty vehicles (such as trucks or trucks) to increase their mileage without increasing the size of the battery pack. Nissan also said that these batteries can reduce the charging time to 1/3 of traditional batteries. On the other hand, sports or supercars can use smaller, lighter battery packs to improve handling, braking and acceleration.

Takei also said that ASSB technology also has a wider range of temperature adaptation. When asked about the optimal operating temperature, he said the batteries could work in the range of "room temperature to 100 degrees Celsius". Therefore, all-solid-state batteries do not need any special cooling system, which means that future Nissan products can reduce more weight and mechanical complexity.

ASSB technology is progressing well according to the plan previously announced by Nissan, and the first pilot production plant is still scheduled to start operating next year. The first mass-produced model using ASSB technology is still expected to be launched in 2028, and when asked for details, Kazuhiro Takai said: "I hope to make the next announcement as soon as possible."

There are still some engineering details to be solved in ASSB technology, mainly to balance the charge-discharge performance and overall life of the battery unit. "first we have to determine the chemical composition before we can estimate the performance of each unit." "in order to achieve a higher energy density, the cathode has to be thicker," he said.... but it will charge more slowly. " Magnesium-sulfur (magnesium sulfur)-based technologies are probably the most cost-effective and can "have a positive impact on cycle life," he said.

CTOnews.com noted that in addition to Nissan, other carmakers such as BMW, Volkswagen and Toyota also put a lot of research and production effort into all-solid-state batteries, but Takei was confident in Nissan's efforts, calling the company a "leading group".

Last month, Nissan announced that every new car launched in Europe would be an electric car and would complete a fully electrified transformation in the region by 2030. "the world needs to get rid of the internal combustion engine (ICE)," Nissan chief executive Makoto Uchida said at the time.
