The single crystal electrode battery, however, showed almost no signs of mechanical stress and looked very much like a brand-new cell. If these batteries can outlast the rest of the EV by such a large amount and still be in good shape internally, that makes them ideal candidates for reuse or repurposing in other applications – like storing energy for intermittent

Once retired from EVs, these longer-lasting batteries can store renewable energy, such as solar and wind power, ensuring a greener future. Although single-crystal electrode batteries are commercially available, they are not yet widely used in EVs.
Over time, these cracks lead to the material's gradual pulverisation, ultimately reducing the battery's performance and capacity. By contrast, single-crystal electrodes demonstrated remarkable resilience. Even after prolonged use, these electrodes exhibited minimal mechanical stress and appeared nearly identical to new cells.
The two electrodes are made from similar materials, but in the polycrystalline electrode, those materials take the form of many tiny particles formed from even smaller crystals packed together. In the single-crystal electrode, as the name suggests, each particle is made from just one crystal, which makes them more resistant to mechanical strain.
