Toyota was one of the first manufacturers to recognize the potential of eco-friendly models. Since the development and launch of the first-generation Prius hybrid, its offerings have expanded considerably. So much so, that today many of its models are only sold with this type of powertrain. However, technological evolution has continued, focusing its attention on pure electrification.
Their progress in this field has been more limited than that of some of their rivals. However, Toyota's financial strength is robust and very powerful, allowing them to develop new technology at a rapid pace. Thus, the company's engineers have been working on solid-state batteries for some time . Their performance is superior to current batteries, and all indications are that they are very close to having them ready and entering production.
Toyota wants to be a leader in electrification around the world
According to Keiji Kaita, Toyota's executive vice president and general manager of the battery division, their progress is significant. They currently have a functional solid-state battery prototype that is offering very satisfactory performance. According to reports from the company, the goal is to develop a battery that retains more than 90 percent of its initial capacity after 30 years of use.
Among the many advantages of this type of battery are higher energy density and, therefore, a longer average range. In addition, they offer faster charging, a longer lifespan, and greater safety against impacts and sudden temperature changes. In the case of the prototypes developed by Toyota, the electrolyte they are using is composed of sulfur.
However, they still have one problem to solve: developing a format that is both strong and flexible. Toyota had planned to showcase this technology at the Tokyo Olympics . The problem is that Covid-19 has led to the postponement of the event to 2021, thus delaying the technology's debut. What they haven't delayed are their plans to begin production.
If everything goes according to plan, the company intends to begin manufacturing these batteries in 2025. Initially, production will be limited, but once they resolve their current issues, they will increase the rate of output. Everything will depend on their progress and that of Panasonic, their main partner in this technological project.
