Lithium-ion batteries

Extra lithium gives a boost


In a lithium-ion battery, anode prelithiation can compensate for the irreversible lithium loss occurring during formation cycles, yet developing an industrially viable method has posed a challenge. Now, a scalable roll-to-roll transfer-printing process is enabling the facile fabrication of anodes with controlled extra lithium, improving battery capacity.
