Toyota has revealed its roadmap for manufacturing various types of batteries for different vehicles over the course of the current decade. The Japanese automaker intends to introduce solid-state batteries to its vehicles by 2027-’28, with a predicted fast-charging time of 10 minutes or less. In addition, Toyota is developing LFP (lithium iron phosphate) batteries for more affordable mass-produced models, with a significant reduction in cost compared to the batteries currently used in the bZ4X. The company also plans to produce three categories of lithium-ion batteries with liquid electrolytes.
The first category, called Performance, is expected to be available in 2026. It will offer a range of over 497 miles (800 kilometers) and a 20% cost reduction compared to the current lithium-ion batteries used in the bZ4X. The recharging time for this battery type is estimated to be 20 minutes or less. The second category, Popularization, will use lithium iron phosphate composition and promises a 20% increase in range and a 40% reduction in cost compared to the bZ4X batteries. The anticipated recharging time for this category is less than half an hour.
Toyota’s third category is called High-Performance, which combines a high nickel cathode with a bipolar structure using lithium-ion chemistry. This battery will be 10% less expensive to produce than the Performance type and will offer a fast charging time of 20 minutes or less. The company plans to introduce these batteries between 2027 and 2028.
Toyota is also investing in solid-state battery technology, aiming to overcome the current challenges associated with shorter battery life. The company aims to have solid-state batteries in mass production by the late 2020s, with an expected range increase of 20% and a fast-charging time of 10 minutes or less.
To further increase electric vehicle (EV) range, Toyota is focusing on improving aerodynamics. Lower battery heights will help reduce the overall vehicle height, resulting in improved aerodynamics and increased range. The automaker plans to reduce battery heights to 120mm or even 100mm in the case of high-performance sports vehicles.
Before introducing these next-generation batteries, Toyota must address issues with its existing EV technology. Although the company has been criticized for its late entry into the EV market, it is now prioritizing battery research and development to catch up with competitors.
