How is the battery made?

The lithium battery production process:

The first step - the preparation of electrode coating

Mainly the electrode active material, binder and solvent are mixed together, after fully mixing dispersion, form a paste.

Step 2 - coated

Will be the first step in the preparation of stock to specify the thickness of coating to the collection of fluid (aluminum foil and copper foil, etc.), and drying solvent.

Find some copper and aluminium, cut some more than copper and aluminium scraps of paper dip in vinegar.Put a piece of paper on the top of a aluminium, put a copper on pieces of paper, a simple chemicalThe batteryIs ready, copper is positive, aluminium is negative, the wet paper is the electrolyte.However, such a "battery" generate electricity is too weak, can only use smart meters detectable.If many of these "little battery" up, make a "battery" aluminum on the copper another "battery" (don't put the pieces of paper between aluminum and copper), when the current is strong, few "battery" base up to light a light emitting diode (a small current can shine through the semiconductor element).If many of these cells up, current will be very strong.Can also put the copper and aluminum into some fruits and vegetables, such as inserted in tomatoes, lemon, so you can make it an interesting "fruit battery".

Battery, also known as the battery, the battery is one of the battery, its working principle is to convert chemical energy into electricity.Usually, people said the battery is refers to the lead-acid battery.Is a kind of is mainly composed of lead and its oxide, electrolyte battery is a sulfuric acid solution.

Lead-acid battery (LEAD - ACIDBATTERY) electrolyte is used in the hydrogen ion concentration is highest when the sulfuric acid solution, the proportion of the sulfur acid is about 1.3 g/cm ^ 3. Whether or traditional and maintenance-free battery is made of the solution.(free maintenance is only used with sulfuric acid absorption of asbestos material to replace the original clapboard, make active material is not easy to fall off, can prolong service life.)

Plate for the lead of the reticular structure, on which the coat chemical reaction of the active material.

Among them: positive plate of the active material of lead dioxide powder, after a full charge looks a little brown.

At the end of the negative plate of active substances for cavernous lead powder, after a full charge for grey metallic lead.

After electrical secondary board are gray.

Discharge: positive plate lead dioxide into lead sulfate, the hydrogen ions in acid electronics into the water.

At the end of the negative plate lead powder into lead sulfate, sulfuric acid root of the electrons in the cathode electron.

The electrons in the outer loop current.

Charging: contrary to the above process, lead sulfate into different energy states of lead dioxide and pure lead.

This is the principle of lead-acid batteries.To make only need to buy the material with respect to OK.I think you just need to know, you'd better to buy need to save trouble!

Battery are introduced the background of the invention:

Lead-acid battery as early as the second world war to the invention, when thespecial is by the battery to coupled, surfaced after using diesel power generation for battery charging.Sailing underwater can only rely on batteries.

Early batteries work principle is the same as now the production is the same, just less expensive life long more often now.

Water battery production methods

1. Rod type battery: in a charcoal stick with a open at one end, to take a piece of paper napkin, rods, tightly wrapped in charcoal, soaked in saturated salt water to take a piece of aluminum foil tightly wrapped in charcoal stick above, with a battery clip, across the opening in the charcoal stick clip on a pole motor, with another battery clip on the aluminum foil, clip on other motor, motor rotation, and voltage of about 0.8 v or so;

2. High quality battery from an aluminum cans, use scissors to tank cover, then use sand paper roll into tubular (sand facing out) wear off the can respectively, then take a piece of paper napkin, make it close to the tank wall, then pour some saturated salt water, make its infiltration napkins, then insert a stick of charcoal, and in its surrounding fill in charcoal, compaction, sticks until full, with a battery clip, across the opening in the charcoal stick clip on a pole motor, with another battery clip on the aluminum skin, and clip on the other motor, motor rotation, and voltage is about 1.5 v.

Motorcycles, electric cars, cars are equipped with a bottle of water and electricity in children (with the battery of sulfuric acid water), sometimes the car at home for a year, or a few months, can't charge.According to sell battery or repair said, this is the battery is broken, need to purchase a new battery, but new to more than 100 pieces, and only a few dollars for a simple repair.

Tools/raw material

To repair the water bottle

Battery supplements (3% dilute sulphuric acid solution)

Methods/step 1

First check whether the charger is in good condition, can find a lamp test (a multimeter so much the better).Two output test whether there is electricity, if in good (bad, to find a good one), recharging the battery (the positive to the positive, negative on cathode) 1 hours, to detect the battery voltage, if the voltage is too low, the preliminary judgment, the battery has a problem.
