Toyota plans to introduce solid-state batteries by 2025

Toyota has hinted that it will deploy solid-state batteries in its hybrid vehicles before introducing the technology to EVs. The company plans to use the revolutionary battery technology in production cars from around 2025. A solid-state battery uses a solid electrolyte in place of the liquid electrolyte solution used in lithium-ion batteries.   

• Benefits of solid-state batteries include quicker charging and reduced heat generation

• Toyota has built a prototype for testing the battery technology

• Toyota Hilux to launch in India next year

Toyota’s strategy for solid-state batteries

Hybrids will continue to play a core role in Toyota’s electrification strategy, and powertrain boss Thiebault Pâquet told our sister publication Autocar UK the benefits of solid-state technology, which include quicker charging, quicker discharging and reduced heat generation. “We can test and evaluate the technology in those circumstances,” he added, suggesting the technology will be refined in less EV-intensive hybrid applications before it makes its way to EVs. The move comes as Toyota reinforces its ongoing commitment to hybrid technology in the coming years.

European boss Matt Harrison explained that Toyota and Lexus will achieve a 70 percent electrified sales mix in Western Europe this year and “hybrid powertrains continue to attract new customers to both brands – especially those that are looking for practical and accessible ways to reduce their carbon footprint”.

European research and development boss Gerald Killman said Toyota will begin selling cars with solid-state batteries from around the middle of the decade, with plans to deliver “higher output, longer range and shorter charging times”. He confirmed that a functioning prototype vehicle equipped with the technology was built last year for testing purposes, with an ongoing development programme centred around durability. “We believe solid-state batteries have great potential for battery electric vehicles,” he added.  

Hints at Toyota’s next-generation hybrid system come as it rolls out an updated Gen5 powertrain in its new Corolla Cross SUV – bringing improved efficiency and performance courtesy of subtle mechanical modifications over the current system used by the C-HR, Corolla, Highlander, RAV4 and Yaris.

Toyota in India

Toyota India currently retails the Glanza hatchback, Urban Cruiser compact SUV, Innova Crysta MPV, Fortuner SUV, Camry Hybrid sedan and Vellfire luxury MPV. In terms of upcoming launches, Toyota will introduce the Hilux pickup in India in January 2022.
