Toshiba Develops Next-Generation Lithium-ion Battery with New Anode Material
Toshiba Corporation announced the development of its next-generation SCiBTM, which uses a new material to double the capacity of the battery anode. The new battery offers high-energy density and the ultra-rapid recharging required for automotive applications, and will give a compact electric vehicle (EV) with a drive range of 320km after only six minutes of ultra-rapid recharging — three times the distance possible with current lithium-ion batteries.
Toshiba launched the SCiBTM as a safe, long-life, fast charging lithium-ion battery in 2008. Since then, the company has constantly refined the technology and improved real-world performance. For its next-generation SCiBTM, Toshiba has developed a titanium niobium oxide anode material that has double the lithium storage capacity by volume of the graphite-based anodes generally used in lithium-ion batteries.
The new battery also offers high energy density and ultra-rapid recharging characteristics, and its titanium niobium oxide anode is much less likely to experience lithium metal deposition during ultra-rapid recharging or recharging in cold conditions — a cause of battery degradation and internal short circuiting.
Toshiba’s current SCiBTM employs a lithium titanium oxide anode, and is known for excellent operating characteristics in respect of safety, long life and rapid charging. It has found wide use in vehicles and industrial and infrastructure applications, including automobiles, buses, railroad cars, elevators and power plants. The high energy density of the battery, and its rapid recharging, have made important contributions to enhancing the convenience and promoting the spread of EV.
In a joint project, Clariant (Switzerland) and Toshiba Corporation (Japan) achieved a breakthrough in the development of the new generation of DVDs: high-density, recordable-once dual-layer HD DVD-Rs (High- Definition recordable DVDs) based on organic dyes, with a storage capacity of 30GB. ... more
