Toshiba has developed a new type of lithium-ion battery with a life span of three times that of a conventional lithium-ion battery

Toshiba has developed a new type of lithium-ion battery that can be recharged for 6 minutes and travel 320 kilometers, which is three times the impressive performance of traditional lithium-ion batteries.

The long charging time and limited endurance have always been the biggest constraint to the popularity of electric vehicles. A few days ago, Toshiba officially announced that it has successfully developed a new generation of lithium ion batteries for SCiB vehicles, which has the advantages of high energy density and rapid charging. According to Toshiba's official measured data(Japanese JC08 standard), this new type of lithium ion battery can reach 6 minutes of charging and travel 320 kilometers, which is three times that of traditional lithium ion batteries.

Toshiba's official website stated in the announcement that the company launched Super Charged Battery(SCiB) in 2008. It uses lithium titanate as a negative electrode and can achieve rapid charging and discharge, with a life of up to 15,000 times. It can also be used in an environment of minus 30 °C.

Through technical research and development, Toshiba developed a lithium ion battery with titanium niobium oxide as the negative electrode material on this basis, and its lithium ion storage capacity is twice that of graphite as the negative cathode material lithium battery. At the same time, Toshiba also showed a sample of a new lithium battery, 50Ah, only 111mm X 194mm X 14.5 mm. It is reported that its charging can reach 90 % of the electricity in 6 minutes, and the lithium battery of traditional electric vehicles can only be filled with 80 % in 30 minutes even if it is filled quickly.

It is reported that after the new generation of lithium batteries have been charged and discharged 5,000 times, they can still maintain more than 90 % of the battery capacity, and the loss rate is extremely low. In addition, rapid filling can also be achieved at a low temperature of minus 10 °C. Toshiba said the new titanium niobium oxide anode and the new generation of SCiB batteries are a disruptive advance that is expected to have a significant impact on the life and performance of electric vehicles. It is reported that the new generation of SCiB batteries are expected to be commercial in 2019.
