The anode is that the negative conductor of the first cell and is often related to the oxidization or unleash of electrons within the external circuit. In a rechargeable cell, the anode is the negative pole during discharge and the positive pole during charging.

Anode lithium battery

The anode in the battery deserves an equal opinion about the overall performance of the battery. To effectively develop a battery with high energy density, the use of high-capacity electrode materials is an important factor. Alkali metals may be the obvious choice for such systems. The most promising types of modern batteries currently in production are based on lithium anodes. Lithium is generally preferable as it is easier to handle than other alkali metals and especially the lightest and most electropositive in the alkali metal family. Also, the low density of lithium metal (0, 534 G / CC) results in a higher specific capacitance value of 3, 86 ah/g, which is exceptional. Thus, lithium batteries have a higher voltage and energy density than any other rechargeable batteries and therefore prefer applications related to portable devices where lightweight and small volume are the main limitations. The advantages of using lithium metal as an anode are as follows:

Good Restaurateur

Very electropositive 

Good mechanical stability

Simple manufacturing / compact design

But despite this simplicity, the practical application of the metal to the rechargeable anode was very difficult due to some important problems. The most important thing is that the Li metal generally tends to deposit as a dendrite or mossy structure during charging and that the disordered metal deposition results in low coulomb efficiency. In fact, such a thin metal li often acts as an active site causing the reductive degradation of electrolytic components. A part of the tank can be electrically isolated and a detachment can also occur. Also, thin metallic lithium can easily penetrate the separator and possibly cause an internal short circuit, leading to heat release and conditional ignition. One of the main reasons for the failure of rechargeable lithium systems is the reactivity of lithium with electrolytes]. The dangerous nature of Li has paved the way for the identification of some other, safer anodic materials with the same electrochemical properties such as lithium.

Positive Terminal Battery Replacement

Make sure to be very careful when replacing your car battery. Also make sure that the engine, lights and everything

The accessory turns off before removing the old battery. Check if the car has a computer-controlled electrical system. Most vehicles with embedded computer systems require an alternative power source or mass storage device to maintain electronic storage when the battery is off. Disconnecting the battery of such a vehicle without a storage device can damage the main computer or other electrical equipment. We recommend that you wear protective glasses during the replacement process. Ensure that the replacement battery meets or exceeds the minimum capacity and CCA rating of your vehicle.

Safety Comes First! Do well.

1. Lower the driver window far enough to access the ignition keys through the window.

2. Turn off the engine, set it to the blind spot or parking position, and turn on the handbrake.

3. Place the storage device in the cigarette lighter or OBD / OBD II connector and turn the ignition key into the accessory position.

4. It is better to perform the replacement in a well-ventilated environment.

5. First remove the negative terminal, then the positive terminal, and wrap the terminal securely with a cloth to isolate it from the short circuit to Earth.

6. Remove the clamp and carefully remove the battery, taking into account the positive and negative positions of the battery terminals.

7. Corroded steel parts must be cleaned and neutralized, dried, and painted.

8. The terminals must be thoroughly cleaned.

9. The terminals of the battery cable and the starter must be checked and tightened if necessary.

10. If the terminals or wires are corroded, they must be replaced.

Positive Terminal Battery Corrosion

Corrosion of the battery?

Corroded battery terminals can prevent your car or vehicle from starting. The corrosion of the battery can also cause many other problems with the car battery, and in particular, for damage to the housing, the car, the electrical wiring, the air conditioning pipes, etc., is sufficient protection for the corrosion of the battery is crucial for the health of the battery of the vehicle and the vehicle.

What Causes Corrosion of the Battery?

The corrosion of the battery is caused by hydrogen gas released from the sulfuric acid in the battery. When the gases react to the surrounding atmosphere, it begins to create a corrosive environment. Normally, corrosion of the battery terminals occurs on the negative battery terminals, which is a symptom of insufficient charging of the vehicle battery. The main culprit for poorly charged batteries is the fact that the generator does not give enough time to replenish the lost battery capacity due to the demand for an electric charge of the vehicle and the relatively short use of the vehicle. If corrosion of the battery is present at the positive terminal of the battery, this is a symptom of overload.

Corrosion Warning:

The content of lead batteries is very corrosive. Any direct contact with the skin or eyes can lead to burns and blindness.

Wear protective clothing and goggles when handling to avoid injury.

Do not allow the electrolytes to escape from the battery housing; it is a dangerous material and must not come into contact with groundwater or drainage systems intentionally or otherwise.

How to Clean Battery Corrosion

To prevent, do not clean, corrosion of the battery should be the purpose of the proper maintenance of the battery. However, if you find a battery with corroded battery terminals, here is a simple process in eight steps. It is always useful to wear eye protection and mechanical gloves when working with lead-acid batteries.

How to Fix Battery Terminal Corrosion

Now that we know what causes the corrosion of the car battery, we need to know how to fix it. You can use different methods to clean the battery terminals.

1. baking Soda – Water Solution

If you want to remove copper sulfate from the connectors, you need a solution of baking powder and a brush. First, make sure that the contact of the vehicle is switched off. Remove the battery terminals and use a brush to remove some of the corrosion. Pour the baking powder solution and remove the corrosion with a brush. Once this is done, clean the clamps with clean water. It is advisable to apply some wheel-bearing grease to the clamps to avoid further damage. Some people may choose Vaseline, but it does not last as long as fat.

2. Soda

Most of the carbonated drinks we drink contain carbonic acid. Pour some soda over the clamps and use a soft sponge to remove the residue. This works well in the absence of a solution of baking soda and water.
