1. Introduction Numerous efforts are constantly underway to replace fossil fuels with renewable energy systems, with the aim of reducing the greenhouse gas emissions associated with power generation. Nevertheless, the unevenness of renewable energy generation and the timing mismatch between supply and demand limit their large-scale integration, especially when renewables are the primary energy source.

Abstract : One of the most promising and heavily researched energy storage systems due to their high energy density, rate capability and extended cycle life are lithium-ion batteries. Their performance and efficiency are nonetheless strongly dependent on their constituent materials and design, including the current collectors. One attractive approach in this respect is the use of metal foams as an alternative to the conventional current collectors.

Abstract : The promised prospects of Li–S technology, especially within the energy situation of the 21st century, have sparked a renewed interest from the scientific community in the 2000s. In this context, we present our new vision for the fabrication of novel cathodes for Li–S batteries that were synthesized using the first combination of composite plating and electroforming (composite electroforming).
