    Toyota and the Tokyo Institute of Technology and High Energy Accelerator Research Organization (KEK) have reported a major advance in battery technology, in the form of new lithium-based superionic, solid-state, conductor materials.

    Toyota’s technology will allow the company to test various materials and battery structures, which is expected to be the basis of an improved electric vehicle in the next several years.

    Enabled by a complex method for tracking lithium ions in storage batteries, the technology holds a potential key to much more efficiency and powerful solid-state batteries. Toyota is also bullish about fuel-cell vehicles and has no plans no change that policy.

    Toyota says new technology means longer battery life

    By Yuri Kageyama
    Toyota Motor Corp. has developed a new way of observing the movements of tiny particles in batteries used to power electric vehicles—an advance it says will help boost their cruise range by 10 percent to 15 percent.

    Toyota engineer Hisao Yamashige explained to reporters Thursday at the Japanese automaker’s Tokyo office the complex method for tracking the lithium ions, which are tiny particles in lithium-ion batteries, also used in laptops and smartphones.

    The ions’ movements, which are extremely hard to detect, are critical in determining the efficiency and power of a battery.

    Increasing cruise range is the biggest obstacle for electric vehicles, especially because charging stations aren’t as common as gas stations.

    Toyota is more bullish about fuel-cell vehicles, which are expensive but can deliver the same cruise range as gas engines. Yamashige said there is no change to that overall company policy.

    Toyota, which makes the Prius hybrid, has no pure electric vehicles in its lineup since production of its electric iQ subcompact and other earlier models were discontinued after selling in only small numbers.

    But all the world\’s major automakers are working on electric vehicles. Japanese rival Nissan Motor Co. leads with its Leaf, which has a range of about 100 miles (160 kilometers) on a single charge. The Nissan-Renault alliance accounts for about half the world’s pure EVs sold. 

    Toyota’s new technology will allow the company to test various materials and battery structures, and an improved electric vehicle is being planned for the commercial market within the next “several years,” said Yoshinori Suga, a department manager.
