Extremely stable Li-metal battery enabled by piezoelectric polyacrylonitrile quasi-solid-state electrolytes

Journal of Materiomics
Polymer solid-state electrolytes (PSSEs) are promising for solving the safety problem of Lithium (Li) metal batteries (LMBs). However, PSSEs with low modulus in nature are prone to be penetrated by lithium dendrites, resulting in short circuit of LMBs ...

Atomic mechanism of lithium dendrite penetration in solid electrolytes

Nature Communications
Abstract Lithium dendrite penetration through ceramic electrolytes is known to result in mechanical failure and short circuits, which has impeded the commercialization of all-solid-state lithium anode batteries. However, the underlying mechanism still remains under debate, due in part to a lack of in situ atomic-level observations of the ...

Direct observation of active material concentration gradients and crystallinity breakdown in LiFePO4 electrodes during charge/discharge cycling of lithium batteries

, 2014
The phase changes that occur during discharge of an electrode comprised of LiFePO4, carbon, and PTFE binder have been studied in lithium half cells by using X-ray diffraction measurements in reflection geometry. Differences in the state of charge between
