Lithium-matrix composite anode protected by a solid electrolyte layer: long lifetime, high safety and high energy density (Pages 29-34) 
Lithium (Li) metal anodes play a paramount role in pursuit of high-energy-density batteries because of ultrahigh specific theoretical capacity. However, short lifetime and disastrous safety pitfall, causing by uncontrolled dendrite growth and volume change, significantly plague the practical application of Li metal anode. Inspired by the house structure for human beings, here a house like Li anode (housed Li) with carbon fiber matrix and solid electrolyte layer was constructed for overcoming the obstacles of Li metal anode. The matrix not only maintains a stable structure but also affords interspace for Li ion deposition. Meanwhile the roof, an artificial solid electrolyte layer, insistently protects Li metal from the corrosive electrolyte and promotes homogeneous Li ion distribution. Benefiting from the combination of matrix and solid electrolyte layer, notorious Li dendrites and volume change during repeated cycling are significantly inhibited and thus a safe and stable Li anode is obtained. This design concept of composite ? anode paves a way for facilitating the practical application of Li metal batteries.
