Last week, Toshiba announced advancements in its Super Charge ion Battery (SCiBTM) design. The new battery tech will double the capacity of the anode, offer high-energy density, and support ultra-rapid recharging. According to Toshiba, the driving range will triple current standards, allowing compact electric vehicles (EVs) to travel almost 200 miles (320 km) after six minutes of ultra-rapid recharging.

The company launched SCiBTM back in 2008. The current version uses lithium titanium oxide as its anode. For the newest iteration, titanium niobium oxide acts as the anode material. This change “has double the lithium storage capacity by volume of the graphite-based anodes generally used in lithium-ion batteries,” according to Toshiba.

“We are very excited by the potential of the new titanium niobium oxide anode and the next-generation SCiBTM,” says Toshiba’s Director of Corporate Research & Development Center Dr. Osamu Hori.

To develop the design, Toshiba put a 50-Ah prototype through a series of strenuous tests. Those trials confirmed it upholds safety, rapid recharging, long life cycle, and low-temperature operation of the current model.

After 5,000 charge/discharge cycles, the next-gen battery sustains over 90 percent of its initial capacity. The new design is also proficient in the cold, demonstrating ultra-rapid recharging in ten minutes at temperatures as low as 14 degrees Fahrenheit (-10 degrees Celsius).

“Rather than an incremental improvement, this is a game changing advance that will make a significant difference to the range and performance of EV. We will continue to improve the battery’s performance and aim to put the next-generation SCiBTM into practical application in fiscal year 2019,” Dr. Hori adds.

With a 2019 commercialization goal, Toshiba aims to continue development on EV range-extending technologies. Until then, check out the designs projected improvements in the chart below, courtesy of Toshiba.
