Unlike the electrode surface measurements, mapping the interface cross-section in a traditional layered battery configuration is constrained by the μm level thickness of the interfacial region and the limited spatial resolution of these techniques.
The development of lithium- ion secondary batteries mainly focuses on the improvement of anode and cathode materials and exploring new materials, which determine the battery’s performance (Chen, 2013; Koksbang et al., 1996; Wang et al., 2015; Zhang et al., 2015; Zou et al., 2015).
Control of ionic conductivities in composite electrodes is important to further improve the performance of lithium-ion batteries. The active material, carbon-coated LiFePO 4 powder, with an average particle size of 200 nm was used. The conductive additive, acetylene black, with a mean particle size of 40 nm was acquired from Denka Black (Japan).
The lithium specificity of this method provides a unique opportunity for monitoring the change of lithium concentration in solid-state lithium batteries. These results help to unravel the underlying cause for the loss of active Li + and the formation of lithium dendrites.
While several types of solid-state lithium-ion (Li +) conductors have been identified as potential candidates for the SEs of next-generation ASLBs, the poor compatibility between electrodes and SE materials still hinders the extension of the battery cycle life.
