Method for internal chemical reaction in battery via charging five times and discharging four times

The invention discloses a method for internal chemical reaction in a battery via charging five times and discharging four times, belonging to the technical field of a battery. The battery is of a 12V12Ah type. The method adopts nine stages with charging five times and discharging four times, and comprises the following steps: immediately placing the battery in cooling water for cooling after acid is added, keeping the battery static for 2 plus 0.5 hours so that pole plates and separators are completely impregnated in sulfuric acid, powering for chemical reaction when the temperature of the battery is reduced to 30-40 DEG C, controlling the water temperature during the chemical reaction so that the temperature of the chemical reaction is no higher than 50 DEG C, starting the internal chemical reaction of the battery, charging a plurality of times with alternating current during the internal chemical reaction, and keeping the battery static for a certain period each time after charging. When the internal chemical reaction in the method is adopted for the battery, the initial capacity of the battery can be increased by 4.1-9.1 percent, the rate of utilization of active substances of the battery can also be increased, and the difference of PbO2 contents inside and outside the finished pole plates can be reduced from 17.1 percent to 5.6-7.6 percent after charging.

Ecological permeable stratal configuration

The invention provides an ecological permeable stratal configuration and belongs to the technical field of water collection and water intaking, and the ecological permeable stratal configuration can be used for solving the problems that because the existing urban surface soil layer is impermeable, moisture exchange and circulation can not be performed between the atmosphere and the soil layer, and after the situation lasts for a long time, the phenomena that the air in cities is extremely humid or extremely dry, and the water in soils below the surface soil layer continuously runs out are caused, thereby destroying urban ecological environments and affecting the human health, and the like. The ecological permeable stratal configuration comprises a surface layer and a water storing layer, wherein the surface layer is permeable and can cover the water storing layer, the water storing layer is arranged below the surface layer and can be used for storing water, and a permeation layer which can guide water flows to permeate downwards is arranged between the surface layer and the water storing layer in an appressed clamping mode. The ecological permeable stratal configuration has a good penetration function, and can achieve the rainwater drainage effect of a road surface; and meanwhile, when the outside is in hot dry climates, rainwater collected in the deep of the stratal configuration can be fed back to the air so as to achieve the effects of humidity adjustment and temperature reduction, thereby effectively solving two serious problems, namely, urban ponding and heat island effect.
