Abstract The synthesis and electrochemical insertion of lithium into the Wadsley–Roth NaNb13O33 phase is studied. Lithium intercalation to form LixNaNb13O33 reaches a value of up to x~15, between 3.0 and 1.0 V vs. Li+/Li at a slow cycling rate, a c

Aluminum is a well-known dopant element as it is used in Li[Ni0.80Co0.15Al0.05]O2 but its optimized usage in Li[Ni x Co y Mn z ]O2 cathodes with x ≥ 0.90 has not been explored in depth. Here, we survey various Al-dopant concentrations (0.5, 1, 2, 3
