Background
The shift towards electric vehicles (EVs) heavily relies on improving energy storage solutions, particularly lithium-ion batteries (LIBs) known for their high energy density and efficiency. However, their adoption is constrained by prolonged charging times and limited battery life. The production of conventional LIB electrodes is not only costly and environmentally detrimental—due to extensive solvent use and waste—but it also creates structures that slow down ion movement, hindering charging speed and battery efficiency. These challenges highlight the urgent need for developing sustainable, economical, and high-performance electrodes to propel the EV market forward.
Description
Northeastern researchers have created a new type of lithium-ion battery electrode that charges quickly and remains stable over time. This electrode is made using a simple one-step stamping process that builds channels into the material to help ions move faster, improving the charging process and the overall strength of the electrode. This method is easier to scale up, cheaper, and less harmful to the environment because it uses fewer chemicals and creates less waste. In tests, this electrode has shown that it can hold its charge capacity well through many charge and discharge cycles and performs better than traditional electrodes in terms of soaking up electrolyte and staying intact, making it a valuable development for batteries in electric vehicles and other uses.
