Nissan Showcases Solid-State Battery Technology: Energy Density Doubled, Charging Time Reduced to One-Third

Recently, at the Tokyo Auto Show held in Tokyo, Japan, Nissan introduced its solid-state battery (ASSB) technology that is under development.

The Vice President of Nissan’s Research Division, Kazuhiro Doi, stated that this technology could potentially lead to a significant advancement for Nissan’s next generation of electric vehicles.

ASSB technology can provide electric vehicle batteries with “almost twice the energy density of existing batteries,” along with faster charging capabilities and lower costs.

By allowing each battery cell to provide more energy, larger, heavier vehicles (like trucks or freight vehicles) can achieve longer ranges without increasing the battery pack’s size.

Nissan also indicated that these batteries could reduce the charging time to one-third of that of traditional batteries.

On the other hand, sports or supercars can utilize smaller, lighter battery packs, thereby improving handling, braking, and acceleration.

These batteries can operate normally in temperatures ranging from “room temperature to 100°C”, which means that solid-state batteries don’t require dedicated cooling systems.

Currently, the ASSB technology is progressing smoothly according to Nissan’s previously announced plans. The first experimental production facility is still expected to start operations next year, and the first mass-produced vehicle using ASSB technology is still anticipated to launch in 2028.
