Cathode Positive Electrode Material Examples

The critical factors that determine the performance and lifetime of solid-state batteries are driven by the electrode–electrolyte interfaces. The main challenge in fabricating all-oxide https://www.wikipedia.org/ composites for garnet-based SSBs has been lowering the thermal processing window in which both good contact and low interfacial resistance can be achieved. We present specific examples of the most common LiFePO4 and LiCoO2 cathodes with a Li-garnet solid-electrolyte. A promising discharge capacity of 118 mA h g−1 (3–4.05 V) with a low interfacial resistance of 62 Ohm cm2 is realized for LiCoO2 with a lithium anode, whereas critical phase instabilities for LiFePO4 are uncovered.

Scientists and engineers from academia, government labs and industry have been working together to overcome technical challenges and limitations in the quest to achieve the optimal combination of battery cost and performance. Figure 5 showed that a certain minimum amount of noble metal had to be exceeded before acceptably low … Read More
