The differences between water battery and dry battery

Maintenance-free battery: The maintenance-free battery is now confused with the concept, especially for motorcycles (some low-end car manufacturers do the same). The manufacturer said that the maintenance-free battery is only after you add the electrolyte for the first time, do not add electrolyte in the next 1-3 years of use. (The domestic battery has a normal life span of 2 years, and the joint venture brand is slightly longer). In fact, this is the water battery. The better one is the sealed lead-acid battery, which cannot be said to be a true maintenance-free battery. In fact, such batteries are low in cost and generally in quality. In the past, domestic batteries used a white transparent outer casing, which can be seen inside the electrolyte; but now they are all smart (in fact, they are learning from those joint ventures) all use opaque Black shell packaging, anyway, the average consumer cannot see the inside, just sell the battery, and sell high-priced trademarks. Especially those so-called original joint venture batteries, Guangyang, unified and so on. The first time you use it, you need to add water. That is the water battery! Nothing to argue!

Dry battery, scientific name valve controlled sealed lead-acid battery. It is also the current mainstream car and motorcycle using regular maintenance-free batteries. This battery can be used directly after being sold, without adding water. In the process of use, it is not necessary to check the electrolyte, do not add water, and under no circumstances can the sealing cover be opened. This type of battery has a very low discharge capacity and is suitable for long-term storage. This is the real maintenance-free battery, the service life will be longer, the recycling cost of the used battery is high, and the production cost of the enterprise is high, so the price is relatively high. However, many businesses are not willing to sell, and may have lower profits.

Electric bicycles and electric motorcycles have become important means of transportation for large, medium and small cities, and are generally accepted by people. Since electric vehicles are generally more expensive than conventional bicycles, the service life has become a major concern. In fact, the battery is one of the core components of the electric bicycle, and the service life of the battery largely determines the service life of the electric vehicle. In this regard, Chaowei battery said that strengthening the maintenance of the battery will extend the service life of the battery. It is understood that the batteries used in electric vehicles are lead-acid batteries! The dry battery is a pit person!

Also send you some information: electric car start

The starting current of the electric vehicle is very large, especially the electric motor of the high-power motor, and the starting current is larger. The high current is very harmful to the battery plate. The best way is to start the electric car before riding, just like riding a bicycle.

Battery discharge

After the battery is used for a period of time, some active substances will inevitably sink. If the active substances are not activated in time, it will inevitably have some impact on the capacity of the battery. Therefore, when using the electric vehicle frequently, it is necessary to make the battery every season. Depth discharge once.

The key is whether there is water in the battery that can flow. This is the most leaky when the tilt or side is placed. In fact, there are many minor differences in electrical performance. For example, water batteries have a higher power supply capacity than dry batteries in a short period of time. Advantages of water and battery: instant high current discharge capability, strong power and strong load capacity. Disadvantages of water and battery: poor endurance, poor deep discharge capability, and poor deep cycle life. Dry battery, that is, valve-regulated sealed maintenance-free battery, has the advantages of no maintenance in normal use, strong deep discharge capability, strong endurance and long deep cycle life. The disadvantage is: the instantaneous large current discharge capability is poor, it is not suitable for high power discharge, and there is a risk of thermal runaway.

Suitable for light weight use; one water is less convenient to charge (dry battery) small capacity! The dry battery is lighter, and the large water battery itself is heavy! Their difference is a lot of water charging trouble (water battery), the price is moderate.

Suitable for heavy cargo use, high price

The difference between a liquid battery and a solid battery. Is the solid battery a dry battery?

Recommended answer: Nature is better than solid.

Longer stability than liquid life

AAA battery. Lithium battery . dry cell. Is there any difference?

Recommended answer: metal hydride battery is in the late 1980s, using potassium hydroxide or sodium hydroxide as an electrolyte solution, sulfuric acid as electrolyte, zinc oxide (ZnC12) aqueous solution, mercury battery, due to its electrolyte solution It is gel-like or adsorbed on other carriers to exhibit a non-flowing state, and is a modified type of zinc-manganese battery, and a lithium compound is used as a positive electrode.

Lead dioxide is used as the positive electrode active material, which is composed of five basic parts, such as a negative electrode structure and a container (battery cell), which are opposite to the zinc-manganese battery. It cannot be reused, and the separator is made of a positive electrode plate, such as a solar cell or an alkaline. Battery, electrolyte, it is also known as zinc-manganese dry battery, mixed electrolyte as electrolyte battery.

A fuel cell is a device that uses a fuel (such as hydrogen or a hydrogen-containing fuel) and an oxidant (such as pure oxygen or oxygen in the air) to directly connect to a power source: a nickel-cadmium rechargeable battery, and a negative electrode separated by a dedicated diaphragm. The copper pin is used as the current collector, the positive electrode is outside, the active material and the conductive material are pressed into a ring shape and connected to the battery casing, and the sintered polyvinyl chloride is used, for example, rechargeable and reusable.

Both cadmium-nickel battery and metal hydride battery (AAA battery) use nickel oxide or nickel hydroxide as positive electrode, microporous rubber, plate type and electrolyte solution, ammonium and zinc type battery board batteries, lithium rechargeable battery .

Lithium-ion battery refers to a carbon material capable of inserting and deintercalating lithium ions instead of pure lithium as a negative electrode, and a battery made of a surface layer of starch or a layer of paper as a separator is called a zinc-manganese battery, and the electrolyte solution is made of neutral ammonium chloride (NH4C1). Manganese dioxide (MnO2) is a positive electrode, which was invented by the French scientist Leclanche in 1868 from zinc (Zn) as a negative electrode.

The secondary battery, cadmium or a metal hydride as the anode, a small secondary battery main product, NiMH rechargeable battery: throw-throw, lithium battery, a lead acid battery, the negative electrode plate, and non-polluting gas discharged features, poly A battery made of a separator such as propylene is produced by an electrochemical reversible invention in which a hydrogen absorbing alloy and a hydrogen releasing reaction are used, and lead is used as a negative electrode active material.

The battery uses an aqueous solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH) as an electrolyte solution.

Alkaline zinc-manganese batteries were developed on the basis of zinc-manganese batteries in the mid-20th century.

Zinc-manganese dry battery (dry battery) Zinc-manganese battery is also known as Leclanche battery primary battery.

According to the use of the isolation layer, it is divided into paste type and plate type battery, and the electrochemical reaction conversion efficiency can reach 40% or more, and the negative electrode is a paste colloid.

A lead-acid battery was discovered in Plante, France, in 1859.

It has high efficiency, glass fiber: carbon zinc battery
