Toyota and Idemitsu Kosan Join Forces to Develop All-Solid-State Batteries

The electric vehicle (EV) market is experiencing a disruptive shift, and major players like Toyota and Idemitsu Kosan are now teaming up to develop and mass-produce all-solid-state batteries. This strategic partnership aims to introduce next-generation batteries by 2027-28, followed by full-scale mass production. Toyota’s recent announcement to pivot towards EVs has propelled the company to find a “technological breakthrough” in solid-state batteries, addressing durability issues and paving the way for mass production.

The Need for All-Solid-State Batteries

As the demand for EVs continues to rise, automakers are in a race to enhance their battery technology to improve driving range and charging efficiency. Solid-state batteries offer a promising solution due to their ability to store more energy compared to current liquid electrolyte batteries. Toyota claims that an EV powered by a solid-state battery could achieve an impressive range of 1,200 km (746 miles) and a charging time of just 10 minutes. However, the high cost of solid-state batteries remains a challenge that needs to be overcome for widespread adoption.

Toyota’s Strategic Pivot to EVs

Toyota, a global leader in the automotive industry, has recognized the need to catch up with competitors like Tesla and Chinese manufacturers such as BYD in the EV market. In June, Toyota unveiled its strategic plan to prioritize EVs and announced its intention to introduce all-solid-state batteries by 2026. This move signifies a significant shift in Toyota’s focus and highlights the company’s commitment to innovation and technological advancements in the EV sector.
