A new technique for measuring a key discharge property of a single particle from a lithium battery electrode has been demonstrated.

Because they can pack a lot of energy into a small volume, lithium batteries are used to power everything from mobile devices to electric vehicles. To increase their power and energy-storage capacity, it is vital to accurately determine their charging and discharging properties as a function of their state of discharge. However, the composite nature of electrodes makes this challenging since the various components are unevenly distributed and charged particles can take complex paths as a result.

Now, a team led by researchers from Kanazawa University in Japan has developed a technique that can measure the charge/discharge properties of a single particle. The team employed a micropipette to essentially create a battery in miniature on an electrode surface, and they used it to characterize a single particle of an active electrode component.
