Customer ServiceThe origins of such a poor cycling performance are diverse. Mainly, the high solubility in aqueous electrolytes of the ZnO produced during cell discharge in the negative electrode favors a poor reproducibility of the electrode surface exposed to the electrolyte with risk of formation of zinc dendrites during charge.
The manufacturing of negative electrodes for lithium-ion cells is similar to what has been described for the positive electrode. Anode powder and binder materials are mixed with an organic liquid to form a slurry, which is used to coat a thin metal foil. For the negative polarity, a thin copper foil serves as substrate and collector material.
Some important design principles for electrode materials are considered to be able to efficiently improve the battery performance. Host chemistry strongly depends on the composition and structure of the electrode materials, thus influencing the corresponding chemical reactions.
The first stage in battery manufacturing is the fabrication of positive and negative electrodes. The main processes involved are: mixing, coating, calendering, slitting, electrode making (including die cutting and tab welding). The equipment used in this stage are: mixer, coating machine, roller press, slitting machine, electrode making machine.
A standard negative electrode manufacturing technology for automotive Ni–MH cells is the slurry coating process. The paste consists of an alloy powder capable of reversibly storing hydrogen, binder materials, and carbon powders as the main constituents.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
