6 FAQs about [New Energy Battery Power Collector]
Is there a porous current collector for energy-dense and fast-charging batteries?
Traditional current collectors, being impermeable to electrolytes, hinder the movement of Li + ions and restrict the high-rate capability of thick electrodes. Here we conceptualize a porous current collector for energy-dense and extremely fast-charging batteries.
Should current collectors be lighter?
Therefore, making current collectors lighter becomes a promising approach to further increase battery specific energy, especially for lithium metal batteries with high specific energy. However, this strategy is often overlooked in literature.
What is a battery collector made of?
The current collector is composed of a sandwiched, porous and hierarchical polymer matrix coated with roughly 1.5 µm thick cathodic and anodic conductive metal on each side, respectively. Comparing Fig. 1a,b, we would identify one critical change on the configuration of battery cells.
Does weight reduction increase specific energy of a current collector?
Therefore, weight reduction of current collectors enables an increase in the specific energy of these next-generation systems of 5%–20% (20–100 Wh kg −1). Such benefits could release constraints on electrode materials and electrolyte to some extent (e.g., mass loading and electrolyte to electrode ratio).
How does a current collector work?
In typical batteries, current collectors are electrolyte-impermeable (Fig. 1a), and thus the exchange of Li ions between the two sides of a current collector is restricted, which limits Li-ion transport between electrodes to one side only and increases the effective ion transport length.
Is there a porous architecture for Li-ion battery current collectors?
Yi Cui & Yusheng Ye Stanford University, Stanford, CA, USA. “This article reports the formation of a porous architecture for Li-ion battery current collectors based around a Kevlar host, with single-sided porous Cu and Al coatings.
