Mesoporous lithium titanate has been prepared with a titanate morphology that leads to the fastest insertion of lithium. It features a gravimetric capacity of about 175 mA h g−1 and delivers up to 73 % of the maximum capacity at up to 800 C (4.5 s) without deterioration over 1000 cycles. A key feature is a fully crystalline interconnected porous framework composed of spinel nanocrystals of only a few nanometers in size. Scale bar: 10 nm.
