Abstract:Red phosphorus anode, attributed to its high specific capacity of 2596 mAh g−1, is expected to improve the energy density of Na−ion batteries. However, the P anode currently is unsatisfactory for practical usage due to the large volume expansion beyond 300%, which brings out uncontrolled brittle failure. To address this challenge, we here design a nacre−like phosphorus anode by resilient graphene oxide staggered together. The staggered structure simultaneously offers mechanical strength and interwoven toughne… Show more
