Can e-beam irradiation produce solid-state batteries?

High energy e-beam irradiation is promising to produce solid-state batteries. Gel polymer electrolytes deliver excellent electrochemical performances. LFP/Li pouch cells exhibit high safety. The in-situ polymerization is a promising technique for achieving industrial-scale production of solid-state lithium metal batteries (LMBs).

How does high-energy E-beam transform a liquid-state pouch cell into a solid-state cell?

More impressively, high-energy e-beam can penetrate through aluminum-plastic film to induce polymerization, which directly leads to the transformation from the liquid-state pouch cell to the solid-state. The solid-state LFP/Li pouch cell exhibits excellent cycling performance with a capacity retention of 83% after 100 cycles at 60 °C.

How is a high energy E-beam transformed into a GPE?

After the irradiation of high-energy e-beam, the precursor solution transformed into the GPEs by cross-linking reaction at room temperature. Such GPEs exhibit considerable ionic conductivity (0.17 mS cm −1 at 27 °C), high lithium-ion transference number (0.76 at 27 °C) and wide electrochemical working window (5.4 V, vs Li/Li +).

Which adhesive is suitable for electric cehicles prismatic battery assembly?

Bestry’s two-component structural adhesive is suitable for electric cehicles prismatic battery assembly, which can improve the shock resistance of the battery pack and the safety and stability of the battery module. Battery Management System and Charging Pile Conformal Coating

What are the advantages of GPE based lithium-ion batteries?

The obtained GPEs deliver satisfactory ionic conductivity (0.17 mS cm −1 at 27 °C), high lithium-ion transference number (0.76 at 27 °C) and good electrochemical stability (5.4 V, vs Li/Li +). The LiFePO 4 /Li (LFP/Li) batteries based on the GPEs achieve excellent cycling stability (85% retention after 270 cycles) and rate performance.

Can gpe-4 film be applied to high-voltage LMBS?

As can be seen from the Fig. 3 d, there is not obvious oxidation current before 5.4 V (vs Li/Li +), revealing that the GPE-4 film possesses excellent electrochemical stability and is potential to be applied to high-voltage LMBs , .
