In a joint effort to advance electric vehicle (EV) battery technology, Toyota Motor Corp. and Idemitsu Kosan Co. have embarked on a collaborative journey to develop mass-production technology for solid-state batteries. This partnership represents a significant step forward in the quest to improve battery performance, reduce costs, and accelerate the electrification of the automotive industry.
The focus of this collaboration will be on solid sulfide electrolytes, a key component of solid-state batteries that has the potential to significantly enhance EV battery output. Solid-state batteries, as opposed to traditional lithium-ion batteries, offer several advantages, including improved energy density, faster charging times, and enhanced safety. By developing a reliable and scalable manufacturing process for solid-state batteries, Toyota and Idemitsu aim to unlock the full potential of this technology.
In a joint statement released on Thursday, the companies outlined their commitment to establishing a supply chain capable of producing solid-state batteries in high volumes. This supply chain will be a critical component of their efforts to bring solid-state battery technology to the mass market.
Toyota, the world’s largest automaker, announced its ambitious goal in June to commercialize solid-state batteries for electric vehicles by 2027 or 2028. This commitment is part of Toyota’s broader strategy to demonstrate its leadership in the electrification and automation of its vehicle lineup. The successful development and deployment of solid-state batteries have the potential to revolutionize the electric vehicle industry.
Solid-state batteries offer several advantages over traditional lithium-ion batteries. They have the potential to improve the range of electric vehicles while simultaneously reducing costs, making EVs more accessible to a broader range of consumers. Moreover, solid-state batteries are known for their faster charging times, addressing a significant concern for EV drivers.
Idemitsu Kosan, an oil refiner and petrochemicals company, and Toyota are joining forces to form a task force consisting of “dozens of members.” This task force will focus on the development of sulfide solid electrolytes and the establishment of a large-scale battery production facility. The ultimate goal is to enable Toyota to introduce its next-generation battery-based electric vehicles as early as 2027.
Toyota has made substantial commitments to the electrification of its vehicle portfolio. The company has pledged to sell 1.5 million battery-electric vehicles annually by 2026 and increase that number to 3.5 million by 2030. As the global leader in the automotive industry, Toyota is determined to play a significant role in the transition to electric mobility.
In September, Toyota took a proactive step in showcasing its commitment to electric vehicle technology. The company invited the press to tour its manufacturing facilities in Aichi Prefecture, providing a firsthand look at the progress it has made in developing the technology required to scale up electric vehicle production. This commitment to research and development is a testament to Toyota’s dedication to pushing the boundaries of innovation in the EV sector.
The collaboration between Toyota and Idemitsu Kosan represents a significant milestone in the pursuit of advanced battery technology. As the electrification of the automotive industry continues to gain momentum, the development of solid-state batteries is poised to be a game-changer, offering improved performance, safety, and affordability for electric vehicles. Toyota’s commitment to mass-producing solid-state batteries underscores the company’s vision for a sustainable and electrified future in the automotive sector.
