Anyone familiar with electric motion would probably never have heard of it Lithium-titanate batteries From time immemorial Mitsubishi iMiEV And its twins from the PSA team. While these cars were not popular in quality or style – they were really slim users – on the contrary they were well known for their almost indestructible battery pack, thanks to the chemistry mentioned above. And precisely for this reason Toshiba This type of cell is still developing and introducing new ones Supercharged ion battery 20 Ah HP.
Le cell lithium titanium oxide, LTO Or lithium-titanate, they are always lithium-ion batteries, but in Lithium-detonated nanocrystals Are placed on the surface of the anode instead of graphite. This device makes it possible to recharge fast, which gives a very long life for charge-discharge cycles. Reduced energy density Due to low voltage (2.4V).
Toshiba was able to upgrade its SCiB cell by reducing the internal resistance by 40%, thus allowing 1.7 times more input power and 1.6 times more output than the older product. They are obtained due to low resistance Low operating temperature. According to the manufacturer, previously liquid cooled can be cooled by forced air, and even ambient air is cooled by forced ventilation.
Possible applications are in motor generator systems such as light hybrids or full hybrids. Plug-in hybrid, Low density is not a problem. We consider all major modes of public transportation where you can make short high-power charging stops, i.e. i Electric buses Engines with pantograph charging or back-up battery.
As mentioned, the energy density of this solution is low, reaching 176 Wh / L or 84 Wh / kg, but once again the longevity is surprising. Toshiba’s new lithium-titanate cell after 8,000 cycles, according to leaked data It maintains practically unchanging potential.
