Porous current collector for fast-charging 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.
