AI Technical Summary
In existing lithium-ion batteries, the lithium metal electrode has a slow lithium stacking speed, insufficient charge-discharge life characteristics, and lithium dendrite growth leads to short circuits and capacity reduction.
A protective layer consisting of amorphous carbon and silicate clay minerals with a 2:1 layered crystal structure is coated onto the current collector, and a lithium alloy metal layer is formed by electrodeposition process, which improves lithium-ion conduction and blocks dendrite growth.
It improves the charge-discharge life characteristics and electrode structure safety of lithium secondary batteries, prevents short circuits, enhances lithium-ion concentration and uniform distribution, and improves battery energy density and production efficiency.
