摘　　要：充油压力补偿式承压锌银蓄电池是全海深载人潜水器电源的备选技术路线之一,因其特殊的应用环境,承压锌银蓄电池蓄正常工作时需浸入绝缘油中使用,充、放电使用中产生的气体在液体中以气泡的形式排出单体电池,气泡会携带碱液进入电池箱体中对蓄电池系统安全产生威胁,因此必须严格控制蓄电池使用过程中的产气量。全海深载人潜水器用锌银蓄电池在研制时,通过优化极板结构、改进负极及电解液添加剂、优化电池充电制度等措施,相较于蛟龙号载人潜水器用锌银蓄电池,显著降低了析气率。经过测试,全海深载人潜水器用锌银蓄电池在放电倍率提升的情况下析气率最高不大于0.03 mL/Ah,符合≤0.1 mL/Ah指标,满足了11000 m潜水器的使用要求。Oil-filled pressure-compensated pressurized zinc-silver battery is one of the alternative technology routes of power supply for deep-sea manned submersible,because of its special application environment,it is necessary to immerse in the insulating oil to use the pressure-bearing zincsilver battery in the normal operation,and the gas produced in the charging and discharging process is discharged from the monomer battery in the form of bubbles in the liquid,the bubble will carry lye into the battery box,which threatens the battery system security.Therefore,the amount of gas produced in the battery must be strictly controlled.During the development of the zinc-silver battery for all-sea deep-sea manned submersible,some measures were tried to be taken,such as optimizing the structure of the electrode plate,improving the additives of the negative electrode and electrolyte,optimizing the charging system of the battery,etc.,compared with the zinc-silver battery used in Jiaolong manned submersible,the gas evolution rate is significantly reduced.The test results show that the highest discharge rate of the zinc-silver battery is not more than 0.03 mL/Ah with the increase of discharge rate,which meets the requirement of 11000-meter submersible.
