Perovskite, widely used in solar cells, has also been proven to be potential candidate for effective energy storage material. Recent progress indicates the promise of perovskite for battery applications, however, the specific capacity of the resulting lithium-ion batteries must be further increased.
The diffusion coefficients of different samples after 5 cycles. The present 1D perovskite used as the anode for lithium-ion batteries results in high and stable specific capacity addressing most critical issues regarding the performance improvement of perovskite applications in lithium-ion batteries.
Photo-charged battery devices are an attractive technology but suffer from low photo-electric storage conversion efficiency and poor cycling stability. Here, the authors demonstrate the use of perovskite solar cells in conjunction with a lithium ion battery which displays excellent properties.
Among many solid electrolytes, the perovskite-type lithium-ion solid electrolytes are promising candidates that can be applied to all-solid-state lithium batteries. However, the perovskite-type solid electrolytes still suffer from several significant problems, such as poor stability against lithium metal, high interface resistance, etc.
It is worth noticing that after the current density dropped from 1500 to 150 mA g −1, the stable specific capacity further restored to 595.6 mAh g −1, which was 86% of the initial stable capacity, showing the potential of perovskite-based lithium-ion batteries for fast charge and discharge.
We have successfully fabricated three different dimensional perovskites as the anodes in the lithium-ion battery.
