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
