Beschreibung:
<jats:p>Blended cathode materials made by mixing LiFePO<jats:sub>4</jats:sub> (LFP) with LiMnPO<jats:sub>4</jats:sub> (LMP) or LiNi<jats:sub>1/3</jats:sub>Mn<jats:sub>1/3</jats:sub>Co<jats:sub>1/3</jats:sub>O<jats:sub>2</jats:sub> (NMC) that exhibit either high specific energy and high rate capability were investigated. The layered blend LMP-LFP and the physically mixed blend NMC-LFP are evaluated in term of particle morphology and electrochemical performance. Results indicate that the LMP-LFP (66:33) blend has better discharge rate than the LiMn<jats:sub>1-y</jats:sub>Fe<jats:sub>y</jats:sub>PO<jats:sub>4</jats:sub> with the same composition (<jats:italic>y</jats:italic>=0.33) and NMC-LFP (70:30) delivers a remarkable stable capacity over 125 cycles. Finally, <jats:italic>in situ</jats:italic> voltage measurement methods were applied for the evaluation of the phase evolution of blended cathodes and gradual changes in cell behaviour upon cycling. </jats:p>
