The valve-control type sealed lead-acid battery comprises a plate group composed of a positive electrode plate and a negative electrode plate, a partition plate, a casing group and electrolyte, wherein the positive electrode plate is of a tubular structure, and sulfuric acid electrolyte is filled in micropores of the electrode plates and the partition plate in adsorption mode. Colloid electrolyte formed by mixing dilute sulphuric acid and nano-silicon sol is filled in gaps on the portion lower than a busbar of the electrode plate group and between the surrounding of the electrode plates and the casing group. The valve-control type sealed lead-acid battery is capable of well achieving deep circulation and strong in charging recovering capability after deep discharging.
Description
Technical field
The utility model relates to the lead acid accumulator technical field, relates in particular to a kind of valve controlled sealed lead-acid accumulator.
Background technology
21st century, battery industry was the important component part of new energy field, was the new focus of global economy development.Lead acid accumulator accounts for 1/3rd of battery industry gross sales amount, and is closely bound up with industries such as electric power, traffic, information.Have a wide range of applications at emergency power supply, uninterruptible power system, new green power aspects such as (wind energy, solar energy).
Common valve controlled sealed lead-acid accumulator by: positive plate (paste spread type), negative plate (paste spread type), dividing plate (AGM), electrolyte (dilute sulfuric acid), shell group are formed.As in the lead acid accumulator industry important one used in a large number and widely because of its in use non-maintaining, no acid solution leaks outside to pollute.But its positive plate of common valve controlled sealed lead-acid accumulator be the paste spread type structure in use positive active material constantly expand along with the carrying out that discharges and recharges and contraction is destroyed its inherent structure to cause the active material softening and shedding to make battery failure.Common analysing valve control type lead-acid accumulator battery electrolyte is to satisfy the compound needs of oxygen to adopt the design of lean solution amount.The battery of lean solution amount design is high to the requirement of environment for use, charging/discharging apparatus, receives above-mentioned factor affecting in use to be prone to cause the battery thermal runaway and causes losing efficacy.
Therefore, need a urgent technical problem that solves to be exactly instantly: how can propose a kind of effective measures, to solve the problem that exists in the prior art.
The utility model content
The utility model technical problem to be solved provides a kind of valve controlled sealed lead-acid accumulator, can be good at realizing dark circulation, and the charging recovery capability is strong behind deep discharge.
In order to solve the problems of the technologies described above, the utility model provides a kind of valve controlled sealed lead-acid accumulator, comprises utmost point crowd, dividing plate, shell group and electrolyte that positive/negative plate is formed; Positive plate adopts tubular structure, adsorbs sulfuric acid electrolyte abrim in the micropore of pole plate and dividing plate.
Further, said positive plate is a flat pipe type or box-section tubular.
Further, said positive plate comprises the bone core of being processed by lead-calcium alloy or low-antimony-lead alloy, and is centered around the outer comb of being processed by terylene or glass fiber of bone core.
Further, said dividing plate is PVC micropore SiO2 composite diaphragm or AGM dividing plate.
Further, said cap group comprises common valve controlled sealed lead-acid accumulator cap group and preposition terminal valve controlled sealed lead-acid accumulator cap group.
To sum up; The utility model provides a kind of valve controlled sealed lead-acid accumulator; Thereby its positive plate adopts tubular structure to avoid battery active material loose or dislocation in use to cause cycle performance of battery poor; The deficiency that useful life is short, thus the design of flat tube, rectangular tube makes itself and dividing plate contact-making surface greatly the high-rate battery discharge characteristic not had obvious influence again simultaneously.
Simultaneously; Electrolyte adopts the mixture of dilute sulfuric acid and Nano silica sol; To increase the electrolyte liquid measure, wherein dilute sulfuric acid electrolyte is full of battery pole plates inner active material micropore and dividing plate micropore to colloidal electrolyte after solidifying by the design of rich solution amount, is used to satisfy battery charging and discharging and uses.Colloidal electrolyte is distributed in and removes active material and dividing plate micropore in the battery with exterior domain, and battery can not dried up, and the thermal runaway risk is little during use, and the acceptance of charging is good, and battery life is also longer.
