![]() Li-ion batteries are composed of cells in which lithium ions move from the positive electrode through an electrolyte to the negative electrode during charging and reverse process happens during discharging. Lithium (Li)-ion batteries are by far the most popular energy storage option today and control more than 90 percent of the global energy storage. Under a supportive policy framework, nations have increased their energy storage capacity but it is estimated that it is still not enough to satisfy the expecting demands. ![]() According to the joint report from World Economic Forum, Global Battery Alliance, McKinsey, the energy requirement of rechargeable batteries needs to reach 3,562 GWh in 2030, which translates to ten millions of new electric vehicles around the world per year. Understanding the factors controlling battery capacity and, critically, their degradation mechanisms to ensure long-term, sustainable and safe operation requires detailed knowledge of their microstructure and chemistry, and their evolution under operating conditions, on the nanoscale.Īs the world is accelerating to the decarburization, the demands for rechargeable battery systems have become crucially urgent. ![]() The worldwide developments of electric vehicles, as well as large-scale or grid-scale energy storage to compensate the intermittent nature of renewable energy generation has generated a surge of interest in battery technology. ![]()
