obtained does not decompose, forming only small amounts of Li2CO3. It can be established that the irradiation produces consolidation, which is not favourable for an efficient extraction of tritium. Finally, it could be demonstrated that nitrate precursors are not necessary in the combustion method to produce γ-LiAlO2 with high purity. Key words: urea; oxide; combustion; lithium aluminate; ceramic 1......

of the LiNi0.8Co0.1Mn0.1O2 samples are compared in accordance with the lithium source used, as shown in Fig. 3. All the charge-discharge profiles are indicative of one phase lithium extraction–insertion... with different lithium sources under different synthesis conditions exhibit very different charge–discharge performances. The sample synthesized via the procedure of sintering at 800 °C after heating lithium......
