Phase-pure Narsarsukite Na2TiOSi4O10, prepared by solid-state reaction, was found to reversibly (de)intercalate one lithium by utilizing the Ti(IV)/Ti(III) redox couple. Registering a low operational voltage at 0.58 V, it delivered near theoretical capacity of 70 mAh·g-1 at a rate of C/10. Excellent...
