LedningsvevSAnoden

LedningsvevSAnoden is a concept in electrochemical materials science referring to a conductive tissue-like network integrated into the anode material of energy storage and electrochemical systems. The term combines ledningsväv, meaning conductive network, and anode. The concept envisions a porous, interconnected matrix of conductive fibers or filaments embedded in the anode to improve electronic pathways and mechanical integrity.

The term arose in technical literature in the 2010s as researchers sought to improve current distribution and suppress dendrite formation in high-rate batteries. The capital S within ledningsvevSAnoden is sometimes interpreted as indicating a segmented or composite network.

The network is typically composed of carbon-based materials, metals, or conductive polymers. It forms a percolating path for electrons, reducing contact resistance, and can be designed to accommodate volume changes during cycling. The interface with electrolyte is often modified to promote stable solid-electrolyte interphase formation and enhanced ion transport.

Fabrication methods include electrospinning to create fibrous mats incorporated into the anode, in situ electrodeposition of conductive networks, and additive manufacturing to pattern the conductive scaffold within the electrode.

Applications span lithium- and sodium-based batteries, supercapacitors, and water electrolysis systems, with aims to enhance rate capability, reduce polarization, and extend cycle life. It is also studied as a means to mitigate dendrite growth in lithium metal anodes.

Key challenges include scalable production, interfacial stability with electrolytes, long-term durability under high-voltage operation, and integration with existing cell designs. Research is ongoing, with several lab-scale demonstrations but limited commercial deployment.

Related topics include conductive networks, electrode design, dendrite suppression, and lithium metal anodes.
