Electric vehicles have long struggled with two major challenges: lengthy charging times and limited driving range, which have hindered their widespread adoption. However, recent advancements from Toshiba could change the game. The company has officially announced the development of a next-generation SCiB lithium-ion battery for electric vehicles, featuring high energy density and ultra-fast charging capabilities.
According to official data from Toshiba (measured under the Japan JC08 standard), this new battery can be charged in just 6 minutes and provide a driving range of up to 320 kilometers—three times that of conventional lithium-ion batteries. This breakthrough marks a significant leap forward in EV technology.
Toshiba first introduced its Super Charge Ion Battery (SCiB) back in 2008, using lithium titanate as the negative electrode material. This design allows for rapid charge and discharge cycles, with a lifespan of up to 15,000 cycles and the ability to function in temperatures as low as -30°C. Over time, the company has continued to innovate, developing a new lithium-ion battery that uses titanium lanthanum oxide as the anode material. This material offers twice the lithium ion storage capacity compared to traditional graphite-based batteries.
A sample of the new battery, with a capacity of 50Ah, measures just 111mm x 194mm x 14.5mm. It claims to reach 90% charge in only 6 minutes, far outperforming current fast-charging systems, which typically achieve around 80% in 30 minutes. Even after 5,000 charge-discharge cycles, the battery maintains over 90% of its original capacity, showing minimal degradation. Additionally, it supports fast charging at temperatures as low as -10°C.
Toshiba describes the new titanium tantalum oxide anode and the improved SCiB battery as a disruptive innovation that could significantly enhance battery life and performance. The company expects these batteries to be commercially available by 2019.
While the technology is impressive, some users have raised concerns about the need for standardized charging infrastructure. They suggest that unifying battery specifications and enabling battery swapping at service stations could accelerate the adoption of electric vehicles. Although early efforts by state power grids aimed to implement such standards, resistance from automakers—who often sell batteries as part of their vehicle packages—has slowed progress.
Looking ahead, many believe that electric vehicles can eventually replace fuel-powered cars if they meet key criteria: a range of over 800 kilometers (with air conditioning), a charging time under 10 minutes, and widespread charging stations along highways. If these conditions are met, along with more affordable pricing, the transition to electric mobility could happen much faster than expected.
