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 SCiB 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.
Building on this heritage, Toshiba has developed a proprietary method for synthesizing and disarranging crystals of titanium niobium oxide and storing lithium ions more efficiently in the crystal structure. The anode of the next-generation SCiB realized through this approach has double times the capacity of the anode of current lithium-ion batteries.
“We are very excited by the potential of the new titanium niobium oxide anode and the next-generation SCiB,” said Dr. Osamu Hori, Director of Corporate Research & Development Center at Toshiba Corporation. “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 SCiB into practical application in fiscal year 2019.”
Rigorous testing of a 50Ah prototype of the new battery has confirmed that it retains the long life cycle, low-temperature operation, excellent safety and rapid recharging characteristics of the current SCiB. The energy density by volume of battery is twice that of the current SCiB. The next-generation SCiB maintains over 90% of its initial capacity after being put through 5,000 charge/discharge cycles, and ultra-rapid recharging can be done in cold conditions, with temperatures as low as minus 10oC, in only ten minutes.
