Researchers Have Made the Production of Batteries Cheaper and Safer

Researchers at Aalto University, Finland have developed a method for producing lithium batteries that is cheaper and more environmentally friendly tFinnish researchers found a way to significantly improve the durability of Lithium-ion batteries by covering the electrodes of lithium iron phosphate batteries with extremely thin protective layers, and by increasing the potential of lithium iron phosphate used as a positive electrode by doping.Finnish researchers found a way to significantly improve the durability of Lithium-ion batteries by covering the electrodes of lithium iron phosphate batteries with extremely thin protective layers, and by increasing the potential of lithium iron phosphate used as a positive electrode by doping.han previously used methods. This new process has succeeded in replacing the harmful methylpyrrolidone (NMP) solvent, which is traditionally used in the manufacturing of electrodes, with water. Removing this harmful solvent from the production process makes the production of batteries simpler and safer for employees. Production costs of batteries can be decreased by as much as 5 percent. Some of this savings comes from the reduced cost of transporting and recycling harmful chemicals and a lower risk of exposure to employees.

– Improving production methods is important as the use of batteries is rapidly increasing around the world. The increase in electric car use in particular will strongly increase the global demand and production of batteries, says Tanja Kallio, Adjunct professor at Aalto University.
