The main focus of energy storage research is to develop new technologies that may fundamentally alter how we store and consume energy while also enhancing the performance, security, and endurance of current energy storage technologies. For this reason, energy density has recently received a lot of attention in battery research.
This roadmap presents the transformational research ideas proposed by “BATTERY 2030+,” the European large-scale research initiative for future battery chemistries. A “chemistry-neutral” roadmap to advance battery research, particularly at low technology readiness levels, is outlined, with a time horizon of more than ten years.
Batteries assist in converting electric energy into chemical energy thus performing green transfer/storage of electric energy into chemical energy and conversion of chemical energy into electrical when needed .
The roadmap suggests research actions to radically transform the way we discover, develop, and design ultra-high-performance, durable, safe, sustainable, and affordable batteries for use in real applications. This is a collective European research effort to support the urgent need to establish battery cell manufacturing in Europe.
Conversion between electric and chemical energy inside batteries takes place at the interfaces between electrodes and electrolytes. Structures and processes at these interfaces determine their performance and degradation.
Battery research occurs throughout the value chain of battery development. It can be oriented toward battery cells, based on competences in chemistry, physics, materials science, modelling, characterization, etc. It can also be oriented toward systems where the battery cells are integrated into packs, to be used in different applications.
