Toyota has laid out a new strategic roadmap for electric vehicles which will see it develop EV batteries with a range of 900 miles “or more” using solid-state technology.
According to a report by Automotive News, the Japanese automaker is aiming to achieve this goal with a solid-state battery that may be powering Toyota EVs by 2028.
Along with an assortment of other futuristic EV technologies, Toyota says it is committed to bringing a sequence of new battery types into production during the coming five years. The first goal is a next-generation lithium-ion battery offering 600 miles of range per charge, expected to be available by 2026 for use in an all-electric Lexus.
From this stepping stone, Toyota executives claim the automaker will develop a bipolar lithium-iron phosphate battery that cuts costs by around 40 percent. This should lead to a battery with an approximate 660-mile range in 2026 to 2027, followed by an advanced version the following year with 10 percent greater range.
The company plans to introduce a solid-state battery with a roughly 720-mile range by 2027, followed by a 900-mile advanced version by sometime in 2028. Hiroki Nakajima, the automaker’s chief technology officer, stated that Toyota is “determined to be the world leader in batteries.” He added that the company views as crucial “to make these batteries compatible with any kind of model.”
GM is also working on solid-state battery tech that could potentially help it rival Toyota at some point. As far back as 2019, The General received $2 million in federal funding from the U.S. Department of Energy to develop solid-state batteries for EVs. The funds were part of a bigger $9.1 million package and were earmarked for specific goals.
By early 2021, GM was already planning for a second generation of Ultium batteries offering a 500 to 600 mile range overall. A few months later, in April 2021, GM said it was researching several different battery technologies to see which would provide lowered battery costs.
The technologies under consideration included solid state and high-voltage electrolytes, dry processing of electrodes, and silicon-rich and lithium metal anodes. More recently, in February 2023, GM China received the 2022 R&D 100 award for development of new high-power bipolar solid-state battery tech.
Solid-state batteries like those GM and Toyota are developing will provide approximately 250 percent of a standard lithium battery’s charge, avoid the heat issues of liquid batteries, are lighter and offer greater longevity.
