Embodiment

The utility model embodiment is elaborated below in conjunction with the accompanying drawings.

Embodiment：As Figure 1-4, a kind of battery suitable for high altitude localities, including it is top cover 3, positive plate 6, negative Pole plate 8 and cell jar 9, maintenance and repair is carried out to battery in order to facilitate the later stage, top cover 3 and cell jar 9 can be led to Cross hinged mode to connect, hinged mounting means is simple, and installation rate is fast, and cost is low, can effectively reduce storage The manufacturing cost of battery.

Polylith positive plate 6 and polylith negative plate 8 to be parallel to each other between any two, and simultaneously with the bottom land phase of cell jar 9 Vertical mode is arranged in cell jar 9, and pole plate is that the lead plaster by grid and containing active material is formed, and is divided into just by effect Pole plate 6 and negative plate 8, the main function of pole plate are：The parent of electrochemical reaction, the electrode that voltage is formed, electric current formed turn Body is changed, is to determine the life of storage battery and the significant components of electrical property, the lattice-shaped object that grid is cast by lead-containing alloy can conduct The carrier of active material plays a part of the support of skeleton and sticks active material, and afflux can be played as the conductor of electric current, is converged Stream, the effect of defeated stream, can play a part of in balanced current distribution active material as the equal fluid of pole plate.

The active material of positive plate 6 is usually lead dioxide powder, seems somewhat inclined brown, negative plate after fully charged 8 active material is usually spongy lead powder, and two steps are greyish white when being discharged after fully charged for the grey of metallic lead Color, during electric discharge：The brown lead oxide of positive plate 6 is converted into lead sulfate, and the hydrogen ion in acid obtains electronics and is converted into water, negative pole, 8 lead powder end It is also converted to lead sulfate, sulfate radical betatopic produces electronics in negative pole, and electronics produces electric current in external loop, during charging：With it is upper Process is stated on the contrary, lead sulfate is converted into brown lead oxide and pure lead with different-energy state, to ensure the usability of battery Energy.

In order to improve capacity, the quantity of the negative plate 8 in battery than positive plate 6 quantity more than one piece, due to positive plate 6 Active material brown lead oxide mechanical strength it is poorer than the pure lead of negative plate 8, when becoming lead sulfate after electric discharge, volume will increase, The mechanical strength of positive plate 6 is poor, and it is stronger to chemically react, so in each single lattice battery, negative plate 8 is always than positive pole Plate more than 6 is a piece of, and each positive plate 6 will not be put all between two panels negative plate 8 because of two sides after so ensuring that dress conjunction Electricity is uneven, and forming arching makes active material largely come off, because negative plate 8 is than positive plate more than 6 in each single lattice battery A piece of, so the capacity of battery cell is determined with the number of 6 numbers of positive plate, pole plate number is got in single lattice battery More, polar plate area is bigger, and porous is better, then simultaneously more with the active material of sulfuric acid chemically reactive, so capacity is got over.

It is interspersed between polylith positive plate 6 and polylith negative plate 8, dividing plate is separated between above-mentioned positive plate 6 and negative plate 8 7, aforementioned barriers 7 are porous plate, and multiple through holes are randomly distributed in aforementioned barriers 7, and dividing plate 7 is made up of porous mass, can be inhaled Attached a large amount of electrolyte, electrolyte free diffusing and positive and negative ion free migration can be made to participate in electrode reaction, every 7 effect is main It is：The carrier of electrolyte, positive plate 6, the short circuit of the contact of negative plate 8 can be prevented, positive/negative plate can be made to realize beeline, can hindered Slow pole plate lead plaster material comes off and by damaged wound, and the material that pole plate can be prevented to come off does not contact with adjacent plate, can prevent electrode Harmful substance migrated and spread by dividing plate, so dividing plate should possess：Strong adsorption force, aperture is small, porosity is high, hole is total Area is big, and resistance is small, high mechanical strength, acid-resistant corrosion and chemically-resistant oxidisability are strong, generally using glass fibre as raw material.

Positive plate 6 is above-mentioned negative by the way that the cluster connecting plate 5 that polylith positive plate 6 is connected can be connected to positive terminal 1-1 Pole plate 8 is by the way that the cluster connecting plate 5 that polylith negative plate 8 is connected can be connected to negative terminal 1-2, and positive terminal 1-1 is with bearing Extremely sub- 1-2 is exposed to be connected on surface with external device, in order to ensure positive terminal 1-1 and negative terminal 1-2 use Performance, protective cover can be increased at positive terminal 1-1 and negative terminal 1-2, it is necessary to during charge or discharge, protective cover can be beaten Open, protective cover can also be made up of the low plastic material of thermal conductivity factor.

Height above sea level is higher, and temperature is lower, and the influence to battery is bigger, and battery is easy to solidify and then influence battery Performance, in order to reduce influence of the ambient temperature to battery, intrusion of the ambient temperature to internal storage battery is reduced, upper State the upper surface of cell jar 9 be provided with can be by high phenyl siloxane rubber material along the cell body elastic fin 9-1 of one week, elastic fin 9-1 It is made, phenyl siloxane rubber, which is applied, is requiring the occasion such as low temperature resistant, heat-insulated, and middle phenyl and high phenyl siloxane rubber are due to processing difficulties Physical and mechanical properties is poor, and production and application are to introduce diphenyl in the strand of vinylsiloxane rubber by a definite limitation Siloxane unit（Or methyl phenyl siloxane chain link）And it is manufactured, this is to destroy dimethyl by introducing the phenyl of large volume The regularity of siloxane structure, the crystallization temperature and glass transition temperature of polymer are reduced, now, the hardening temperature of rubber drops to most Low value（-115℃）, make it that there is optimal resistance to low temperature, still there is flexible elastic force at -100 DEG C.
