Battery life doubled when scientists held lithium-ion cells at 12.5 bar, because too little pressure cracked cathodes and too much pressure triggered lithium plating
New research reveals a simple mechanical tweak could significantly extend the life of lithium-ion batteries. By maintaining pouch cells at a specific stack pressure of 12.5 bar, scientists nearly doubled their cycle life compared to cells under lower or higher pressures. This breakthrough, which addresses overlooked mechanical stresses, could revolutionize the design of electric vehicles and electronics by offering a longer-lasting power source without altering battery chemistry.
