) (H2‐DPC), has been used to prepare a series of lithium salts Li[B(DPC)(oxalato)], Li[B(DPC)2], Li[B(DPC)F2], and Li[P(DPC)3]. The phosphoryl‐rich character of these anions was designed to impart flame‐retardant properties for their use as potential flame‐retardant ions (FRIONs), additives, or replacements for other lithium salts for safer lithium‐ion batteries. The new materials were fully characterized
功能化的儿茶酚酸盐,(2,3-二羟基-1,4-苯撑)四(膦酸)四乙酯(H 2 -DPC),已用于制备一系列锂盐Li [B(DPC)(草酸)], Li [B(DPC)2 ],Li [B(DPC)F 2 ]和Li [P(DPC)3 ]。这些阴离子的富含磷酰基的特性旨在赋予其阻燃性能,以用作潜在的阻燃离子(FRIONs),添加剂或替代其他锂盐,从而制成更安全的锂离子电池。充分表征了新材料,并形成了Li [B(DPC)(oxalato)]和Li [P(DPC)3的单晶结构。]已经确定。四种锂盐的热重分析表明,它们在高达200°C的温度下都具有热稳定性。热解燃烧流热法表明这些盐在燃烧时产生高炭产率。
