Herein, ultrafine layered graphene/graphite nanosheet composites (GGNCs) with low content of defects are produced via jet cavitation which is scalable and can afford gram‐scale, kilogram‐scale, or ton‐scale quantities of GGNC in less than 1 s, min, h, or day. The as‐produced composites are used as lithium ion battery anodes and are shown to possess a reversible specific capacity of ≈480 mAh g⁻¹ (much higher than ≈372 mAh g⁻¹ in commercial graphite anode) at 100 mA g⁻¹ current density after 100 cycles. They also exhibit excellent rate capability, especially at high current rates (e.g., 301.8 mAh g⁻¹ at 2 A g⁻¹), due to the outstanding conductivity and favorable electrode/electrolyte contact. This work demonstrates jet cavitation as a scalable, low‐cost, and environmentally friendly pretreatment route for commercial carbon‐based anode materials, which can increase the anode specific capacity by 30%.

可喷射和高性能通过喷射空化的锂离子电池石墨烯/石墨纳米片复合阳极

在此，通过喷射空化生产出具有低含量缺陷的超细层状石墨烯/石墨纳米片复合材料（GGNC），该空化具有可扩展性，并且可以在不到1 s，min的时间内提供克级，千克级或吨级数量的GGNC。 ，小时或天。所生产的复合材料可用作锂离子电池阳极，并显示在100 mA g ^-1电流下具有约480 mAh g ^-1的可逆比容量（远高于商用石墨阳极的≈372 mAh g ^-1）。100个循环后的密度。它们还具有优异的倍率性能，尤其是在高电流率（例如，301.8毫安g ^ ^-1在2 A G ^-1），这归因于出色的导电性和良好的电极/电解质接触。这项工作证明了射流气蚀是一种可扩展的，低成本的，环保的商业碳基负极材料预处理路线，可使阳极比容量提高30％。
