Biomass-derived carbon (BDC) is viewed as one of the most promising anode candidates for sodium-ion batteries (SIBs) owing to its natural abundance, low cost, and sustainability. However, fabrication of BDC with a preferred microstructure and morphology for high-performance sodium storage still remains a dilemma. Herein, we
1. Introduction Thermal energy is a kind of indispensable energy to people''s life and production activities, its storage is of vital significance and very beneficial in many fields, such as solar energy conversion and storage [1], energy-saving building [2], electronic cooling [3], and the battery thermal management system [4], [5], [6].
Based on the optimized structure of the gas storage device, the operating pressure range was 4– 10 MPa and included the ES, energy hold (EH), and ER conditions. The focus of the analysis was on understanding the flow, heat transfer, and thermal characteristics, assuming that the temperature of the incoming gas was the
Except for pumped storage, other existing electric energy storage technologies are difficult to achieve large-capacity energy storage and not easy to simultaneously meet the requirements in terms of site selection, cost, efficiency, and response.
