Energy storage current collector materials

Can a porous current collector solve fast-charging and energy-dense lithium-ion batteries?

Realizing fast-charging and energy-dense lithium-ion batteries remains a challenge. Now, a porous current collector has been conceptualized that halves the effective lithium-ion diffusion distance and quadruples the diffusion-limited rate capability of batteries to achieve fast charging without compromising the energy density.

What is a current collector in a lithium ion battery?

Hongqing Hao and Rui Tan contributed equally to this study. The current collector is a crucial component in lithium-ion batteries and supercapacitor setups, responsible for gathering electrons from electrode materials and directing them into the external circuit.

What are the different types of current collector materials?

Six different types of current collector materials, including Al, Cu, Ni, Ti, stainless steel, and carbonaceous materials, which were commonly reported and used for batteries were evaluated (Fig. 8 a).

Why are current collectors important?

As a second function, current collectors serve as a substrate to cultivate the growth of active materials. In this manner, costs can be minimized by reducing the number of chemicals and materials, such as binders, conducting carbon additives, and extra precursors, needed for batteries and supercapacitor assemblies.

What is a polymer based current collector?

Polymer-based current collectors Polymers are widely used materials in wastewater treatment [101, 102], as structure-directing agent , as porogen , as coating , etc.
