Which one is better, lithium battery or water battery?

Maintenance-free batteries are 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, which 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, Cheerwin 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 discharge deeply once every season.

For traction tricycles, water batteries are more cost-effective and can be equipped with larger capacity and traction batteries. In addition to the high price, lithium batteries are technically the most suitable for mobile phones. Lithium battery technology advances, but progress is very full.

The water battery you are talking about should be a lead-acid battery. Lead-acid batteries have been used for many years. The technology is very mature, and the advantages and disadvantages are obvious. Compared with lithium batteries, lead-acid batteries store energy and charge in units. There are many gaps in characteristics, dynamic characteristics, etc.;

The current cost of lithium batteries is more expensive than lead-acid batteries due to production processes, materials, labor, etc. As the price of lithium batteries continues to drop, lead-acid batteries are gradually being replaced. This is a general trend.

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation lithium-metal battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate and performance price ratio are better than lithium-ion batteries. Due to its own high technical requirements, only a few companies in the country are producing such lithium metal batteries.

Lithium batteries were first used in pacemakers. The lithium battery has a very low self-discharge rate and a flat discharge voltage, so that the pacemaker implanted in the human body can operate for a long time without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, which is more suitable for integrated circuit power. Manganese dioxide batteries are widely used in calculators, digital cameras, and watches.

In order to develop a variety of superior performance, various materials have been studied to create an unprecedented product.

In 1992, Sony successfully developed lithium-ion batteries. Its practicality has greatly reduced the weight and volume of portable electronic devices such as mobile phones, notebooks, and calculators.

In the 1970s, Exxon's MS Whittingham used titanium sulfide as the positive electrode material and lithium metal as the negative electrode material to make the first lithium battery.

2. In 1980, J. Goodenough discovered that lithium cobaltate can be used as a positive electrode material for lithium ion batteries.

3. In 1982, RRAgarwal and JRselman of the Illinois Institute of Technology discovered that lithium ions have the property of being embedded in graphite. This process is fast and reversible. At the same time, the lithium battery made of lithium metal has attracted much attention, so people tried to make a rechargeable battery by utilizing the characteristics of lithium ion embedded graphite. The first available lithium ion graphite electrode was successfully produced by Bell Labs.

4. In 1983, M. Thackeray and J. Goodenough discovered that manganese spinel is an excellent cathode material with low cost, stability and excellent conductivity and lithium guiding properties. The decomposition temperature is high, and the oxidation is much lower than that of lithium cobaltate. Even if short circuit or overcharge occurs, the danger of burning and explosion can be avoided.

5. In 1989, A. Manthiram and J. Goodenough discovered that a positive electrode with a polymeric anion would produce a higher voltage.

6. In 1991, Sony released the first commercial lithium-ion battery. Subsequently, lithium-ion batteries revolutionized the face of consumer electronics.

7. In 1996, Padhi and Goodenough discovered that phosphates with olivine structure, such as lithium iron phosphate (LiFePO4), are superior to traditional cathode materials, and thus have become the mainstream cathode materials.

With the widespread use of digital products such as mobile phones, notebook computers, etc., lithium-ion batteries are widely used in such products with excellent performance, and are gradually being developed into other product applications. In 1998, Tianjin Power Research Institute began commercial production of lithium-ion batteries. Habitually, people also call lithium-ion batteries lithium batteries, but these two batteries are not the same. Lithium-ion batteries have become mainstream.

Carbon anode material

The negative electrode materials which have been practically used for lithium ion batteries are basically carbon materials such as artificial graphite, natural graphite, mesocarbon microbeads, petroleum coke, carbon fiber, pyrolysis resin carbon and the like.

Tin-based anode material

Tin-based anode materials can be classified into tin oxides and tin-based composite oxides. Oxide refers to an oxide of various valence metal tins. There are no commercial products.
