Abstract The electrode manufacturing for lithium-ion batteries has been systematically evaluated. It has been shown that a proper tailoring of the electrodes can greatly improve both the electrochemical performance and the energy density of the battery. The pre-treatment of the electrode components, the degree of the electrode compacting and the mixing process have proven to have a strong impact on the electrochemical performance of the composite electrodes based on LiNi0.80Co0.15Al0.05O2. In addition, blending LiNi0.80Co0.15Al0.05O2 – NCA with lithium manganese oxide spinel (LiMn2O4, LMS) has exhibited beneficial effects on the discharge capacity of the blends, thus on the energy density and in the same time decreases the Mn dissolution from spinel structure. Moreover, the detailed study of the storage behaviour of LMS/NCA blend reveals that dissolved Mn from spinel structure is re-precipitable on NCA particles and so that less Mn2+ ions will be available in the electrolyte, which can migrate to the anode graphite and deposit thereof.
