With the increase of waste lithium-ion batteries (WLIBs), the recycling of WLIBs has been paid more attention. Lithium metal battery (LMB) has extremely high theoretical specific capacity. However, the decline of cycle performance and the danger of short circuit caused by lithium dendrite formation and dead lithium accumulation are still the most thorny problems for the anode of LMB. Herein, the high value utilization of WLIBs anode graphite was explored, and it was prepared as a 3D frame material for LMB. Liquid-phase reduced graphite oxide nanosheets (lrGO) were prepared from AG, then, ZnO nanoparticles were loaded on lrGO. SEM, EDX and XRD were used to characterize lrGO and lrGO-ZnO , and the electrochemical tests were carried out. The results showed that lrGO and lrGO-ZnO maintained excellent cycle stability. Under the constant current density of 1mA cm-2, the stable cycle of lrGO-ZnO was 700 cycles, and the charge-discharge platform potential difference maintained at 22.5 mV after 200th cycle. The unique 3D structure of lrGO increased the electrode reaction area and suppressed the volume expansion of Li. The loading of ZnO significantly improved the lithiophilicity and cycle stability.

This paper analyses the National Education Policy 2020 (pages 1-32), the official policy document issued by the Ministry of Human Resource Development (India). This paper is written in light of five peda-gogical theories: a). Human Capital; b). Traditional Academic; c). Learner Centred; d). Social Efficiency; e). Social Reconstruction. By identifying the presence of the five theories in the policy and analysing the domi-nant ideologies of education across the whole text, the paper aims to explore the influence of pedagogical philosophies and the relevant factors on educational policy formation and upgrading in India. It discovers that although all five theories exist in the policy, Learner Centred theory is the most dominant. In addition, it also discusses political and socio-economic factors that impact the formation of the Indian educational policy.
