As a flourishing member of the two-dimensional (2D) nanomaterial family, MXenes have shown great potential in various research areas. In recent years, the continued growth of interest in MXene derivatives, 2D transition metal borides (MBenes), has contributed to the emergence of this 2D material as a latecomer. Due to the excellent electrical conductivity, mechanical properties and electrical properties, thus MBenes attract more researchers' interest. Extensive experimental and theoretical studies have shown that they have exciting energy conversion and electrochemical storage potential. However, a comprehensive and systematic review of MBenes applications has not been available so far. For this reason, we present a comprehensive summary of recent advances in MBenes research. We started by summarizing the latest fabrication routes and excellent properties of MBenes. The focus will then turn to their exciting potential for energy storage and conversion. Finally, a brief summary of the challenges and opportunities for MBenes in future practical applications is presented.

作为二维 (2D) 纳米材料家族中蓬勃发展的一员，MXene 在各个研究领域都展现出了巨大的潜力。近年来，人们对 MXene 衍生物、二维过渡金属硼化物 (MBenes) 的兴趣持续增长，促使这种二维材料作为后来者出现。由于优异的导电性、机械性能和电学性能，MBenes吸引了更多研究人员的兴趣。大量的实验和理论研究表明它们具有令人兴奋的能量转换和电化学存储潜力。然而，迄今为止，尚未对 MBenes 应用进行全面、系统的审查。为此，我们全面总结了 MBenes 研究的最新进展。我们首先总结了MBenes的最新制造路线和优异性能。然后焦点将转向它们在能量存储和转换方面令人兴奋的潜力。最后，简要总结了 MBenes 在未来实际应用中面临的挑战和机遇。
