日本东芝（Toshiba）公司日前宣布开发出新一代超级充电离子电池（SuperChargeionBattery，SCiB），它采用一种以钛铌氧化物为负极材料的锂离子电池，其容量是目前的超级充电离子电池一倍。这种锂电池可实现6分钟快速充电，使得电动车续航里程提升至320公里，是目前使用的同类型的锂离子电池（32千瓦时锂电池）的三倍。东芝表示，新一代的SCiB保留了较长的生命寿命、低温使用、安全和快速充电等特性。这款电池在充放电5000次后，还能维持90%以上的电池容量，在零下10℃的低温环境下也仅需10分钟能完成快充。这种电池无疑是完美的，但问题是，东芝未透露其成本，而成本过高已经成为阻碍锂电池发展的最大障碍。目前，新电池的开发仍在继续，预计有望在2019财年实现商业化。
Toshiba Claims Battery Breakthrough: 6 Minute Ultra Rapid Recharge
Toshiba has announced its next-generation SCiB lithium-ion batteries with a new anode material – titanium niobium oxide, that apparently doubles the capacity of the anode of current SCiB.
According to the graph above, a 6-minute charging would enable one to drive three-times further (320 km / 199 miles in JC08) than using a typical lithium-ion batteries (using a 32 kWh battery).
Toshiba said that the new SCiB also retains a long life cycle, low-temperature operation, excellent safety and rapid recharging characteristics of the current SCiB.
Over 90% of capacity is said to be maintained after 5,000 charge/discharge cycles ,and ultra-rapid recharging can also be done in cold conditions, with temperatures as low as minus 10°C, in only ten minutes.
So outside of the density today, its perfect…the only other thing not discussed unfortunately, is the cost per kWh (the main criteria behind the mass adoption of any new battery tech over another), of which could prove to be the most serious stumbling block – so there might be a couple hiccups. Developments are ongoing, as commercialization is planned for fiscal year 2019.
