Description
Technical field
The utility model relates to a kind of valve-control sealed lead acid battery, is meant a kind of solar energy storage valve-control sealed lead acid battery especially, belongs to lead acid accumulator manufacturing technology field.
Background technology
Along with the popularization and the green energy resource development of technology of low-carbon (LC) life idea, to inexhaustible, with the utilization of it green energy resource-solar energy without cease, obtained significant progress.People become electrical power storage in storage battery solar energy converting in order to improve solar energy utilization rate usually, and especially in the torrid areas, day and night temperature is big, and people get used to utilizing by day battery stores solar energy for using evening.Sealed lead acid storage battery is applied in this field widely as a kind of product of energy storage cheaply.Planar structure is generally all adopted on the battery case surface of existing lead acid accumulator, battery pole plates is thicker, usually between 3.5-5.5mm, when using in the torrid areas, have the following disadvantages: 1, because battery case adopts planar structure, surface area is less, and heat-sinking capability is relatively poor, causes when battery operated, programming rate is very fast, very easily overheated, operating ambient temperature is higher in addition, has further aggravated the overheated of battery; 2, battery pole plates is thicker, in the battery case of same volume, has limited the quantity of pole plate, thereby, cause the electrochemical reaction area less, aggravated the accumulation of electric reaction heat, further aggravated the overheated of battery.According to this principle of Ali's knob, battery temperature is greater than 40 ℃ the time, and the every rising 10 of battery temperature is spent, and battery life will reduce by one times.Battery is overheated or temperature is higher, is easy to make electrolyte dry, causes the battery thermal runaway, has a strong impact on the useful life of battery, and the valve controlled sealed lead-acid accumulator life-span that is used for the solar power generation energy storage at present generally has only 6 months～and 1 year.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, provide a kind of rational in infrastructure, processing and manufacturing easily, perfect heat-dissipating, the solar energy storage valve-control sealed lead acid battery that has extended cycle life.
The technical solution of the utility model is: a kind of solar energy storage valve-control sealed lead acid battery, comprise battery cover, battery case, positive plate, negative plate, dividing plate, electrolyte, bus-bar, terminal, vent valve, described battery case surface is provided with the sheet fin.
In the utility model, described dividing plate is a glass fibre separator, and its porosity is 90～96%, the aperture is that 20～30um, thickness are 2～3.5mm's.
In the utility model, described positive plate thickness is that 1.5～2.5mm, negative plate thickness are 1.0～1.8mm.
In the utility model, described fin is selected from a kind of in aluminium, copper, the plastics.
The utility model is owing to adopt said structure, be provided with fin in the battery case outside, make the area of dissipation of battery outer surface enlarge doubly a lot, at high temperature has good heat-radiation effect, make battery thermal accumlation can not take place, and then avoided dehydration and housing to expand, prevented valve-control sealed lead acid battery generation thermal runaway, make battery can be in hot environment operate as normal.Owing to adopt ultrathin positive/negative plate,, can make the electrochemical reaction area improve 2～3 times at the battery case of the same volume more pole plate of can packing into, help the battery high current charge-discharge on the one hand, improve active material utilization, on the other hand, reduce the accumulation of reaction heat.Dividing plate between positive plate and the negative plate adopts porosity height, the big thick fiberglass dividing plate in aperture simultaneously, can store more electrolyte, provides battery heavy-current discharge under high temperature and low temperature condition required electrolyte and moisture content, effectively avoids electrolyte dry.
In sum, the utility model is rational in infrastructure, processing and manufacturing is easy, perfect heat-dissipating, have extended cycle life, and has excellent high-temperature behavior, can realize suitability for industrialized production, is particularly suitable for solar energy storage and uses.
