报道了采用烧结正极与拉浆负极匹配的GNFC 60少维护超高倍率镉镍电池的研究。通过调整烧结基板工艺参数，在正极浸渍液中添加C02+、Cd2+作为电极添加剂与活性物质共沉在电极中，有效提高了电极的电性能和机械强度。混合粘合剂(CMC+电池添加剂)以及导电剂的使用，使负极形成疏水、多孔结构，提供氧复合所必须的三相界面，加大了氧复合能力，提高了电极体积比容量。同时，选择合适厚度(0.16～0.19 mm)、适宜透气率[0.367(m3/m2·s)]的隔膜，以及对电解液的严格控制，使氧复合能力达到最佳，避免了大容量电池使用过程中的热失控现象，既满足电池在10 C5A电流下持续工作能力，又使电池的维护量降至最低，有效地解决电池漏液、爬碱等问题。样品电池的测试结果均满足IEC标准中的各项性能指标。

The development of low-maintenance ultra-high rate Ni-Cd battery, which used sintered Ni electrode as the positive and the pasted electrode as the negative, was reported. The electrical performances and mechani-cal properties of the positive electrode were improved by modifying the substrate processing parameters and adding Co2 + 、 Cd2 + as additives and coprecipitation. The negative electrode with hydrophobic and porous struc-ture provided a three phase interface for O2 recombination and enchanced O2 recombination ability and volume ca-pacity of the electrode. The separator with proper thickness (0.16-0.19 mm) and permeability [0.367 (m3/m2·s) ] was adopted, and the electrolyte quantity was controlled strictly. As a result, the O2 recombination wasoptimized, runaway heat of large capacity battery were prevented the ability of consecutive operation at 10 C5A was satisfied, the maintenance was minimized, the problems of leakage and creepage were solved, and the appli-cation fields were extended. The test results of the battery reached the IEC standard requirements.
