Problems solved by technology
This type of storage battery has the following disadvantages during use: because the inner surface of the battery tank cover is a smooth plane, heat will be generated during use, charging and discharging of the battery, and the moisture in the electrolyte will turn into water vapor when heated. When the exhaust box is opened, a large amount of water vapor will be discharged out of the battery along with the gas, which will cause the loss of water in the electrolyte to be too fast, resulting in shortened battery life

The invention provides a storage battery. The storage battery comprises a battery jar and a storage battery cover for covering the battery jar, wherein the storage battery cover comprises a first cover body and a second cover body; the battery jar is covered with the first cover body, and a backflow hole communicated with the battery jar is formed in the first cover body; the second cover body is positioned above the first cover body; a guide plate fixed on the second cover body is arranged between the second cover body and the first cover body; the overall guide plate is taper-shaped; and the peak of the taper-shaped guide plate is close to the first cover body. The storage battery cover of the storage battery provided by the invention adopts a dual-layer structure; the taper-shaped guide plate is arranged between the two layers of battery cover; and generated water vapor flows along the taper-shaped guide plate, and partial water vapor is re-condensated into water to reflow to the battery jar through the backflow hole in the process when the water vapor rises along the guide plate, so that the water loss rate in an electrolyte is lowered, and the service life the storage battery is improved averagely by 7%.
Description
technical field [0001] The invention relates to the field of storage batteries, in particular to a storage battery with a double-layer battery cover. Background technique [0002] The battery tank and the battery tank cover are the shell of the battery, and are also one of the important components of the battery, which play the role of containing the electrolyte and protecting the battery electrode group. The current storage battery includes a battery tank with multiple electrolyte tanks and a battery tank cover installed on the top of the electrolytic tank. The inner surface of the battery tank cover near the electrolyte side is a plane, and an exhaust box is arranged on the plane. . This type of storage battery has the following disadvantages during use: because the inner surface of the battery tank cover is a smooth plane, heat will be generated during use, charging and discharging of the battery, and the moisture in the electrolyte will turn into water vapor when heated...
