PANalyticalget insightwww.panalytical.com/batteryresearch Solutions forbattery research PANalytical - your best partner Overview As the energy transition from fossil fuel to more sustainablesources becomes important， the need for large-scaleelectrochemical energy storage arises. Currently Li-ionbatteries are present in any portable electronics device andin electrical vehicles. While Li provides a large part of thecurrently available electrode materials， the availability of Lion Earth remains small and thus alternative elements such asNa or Mg are being considered to replace Li. Developmentof low- cost electrode materials using alternative elementsis quickly becoming a topic of high interest in the scientificcommunity. Using in-depth structural analysis made possible by theEmpyrean diffractometer， one can unravel the nature ofphenomena specific to the battery research， leading to abetter understanding of electrochemical mechanism， andultimately to an improved battery design.
