Which one has a longer service life, Polymer lithium battery or lithium battery?

Lead-acid batteries are safe, durable and more affordable for civilian use. There are many kinds of lead-acid batteries. The common ones on the market include power batteries for electric vehicles, batteries for UPS, and batteries for automobile starting use. You can choose the appropriate lead-acid battery according to your field of use. It cannot be mixed. Different functions used in different areas of the life will be greatly affected.

The general warranty for one year is because the battery has been put on for a long time, and it is dormant. After adding the electrolyte, it needs to be charged by the charger. It can be used in about 5-6 hours. The dry battery is added to the electrolyte within about 90 days after leaving the factory. It can be used after half an hour, but it takes a long time to activate.

Lead-acid battery (VRLA), is a kind of electrode is mainly composed of lead and its oxide, battery electrolyte is sulfuric acid solution. Lead-acid battery charged state, the positive main ingredients for lead dioxide, negative main ingredients to lead; Discharge state, the main components are all lead sulfate is negative. A single case of lead-acid battery nominal voltage is 2.0 V, can discharge to 1.5 V, can charge to 2.4 V. In the application, often together with six single lead-acid batteries of nominal is 12 v lead-acid battery, and 24 v, 36 v, 48 v, etc.

May be I see light, really haven't heard of aluminate batteries. Lead-acid battery is safe and durable and low cost is more suitable for civilian use. Lead-acid battery types have a lot of common on the market of electric vehicle power battery, UPS battery, automobile starting batteries, according to you to choose the appropriate use of field lead-acid battery, cannot mix, function different used in different fields of life will be greatly influenced.

Lithium ion battery electrolyte, is relatively safe, Lithium polymer battery using polymer electrolyte, long service life, safety, do not happen bulge bag and so on security hidden danger, so it must be polymer battery more outstanding.

Polymer lithium battery

According to the electrolyte materials that are used in lithium ion batteries, lithium ion batteries are divided into liquid lithium ion battery and Polymer lithium ion batteries Lithium ion batteries or plastic. Is used in the polymer lithium ion battery cathode materials and liquid lithium ion is the same, the anode materials are divided into cobalt acid lithium, manganese acid lithium, ternary material and lithium iron phosphate material, negative extremely graphite, working principle of the battery is almost the same.

Their main difference is that the different electrolytes, liquid lithium ion battery using liquid electrolyte, polymer lithium ion battery with solid polymer electrolyte as a substitute for, the polymer can be "dry", also can be "colloidal", at present most of the polymer gel electrolyte.

The lithium battery

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S. Whittingham proposed and began researching 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 polymers have a long service life.

700-80000 times completely blunt electricity is theoretical data, now the usage of smart phones, normal will decay is very serious in about 300, there are many online detecting battery actual capacity of the software, which can be used to look at your battery.

[Expanding information]

The basic structure of modern batteries includes three elements: positive electrode, negative electrode and electrolyte. As a kind of battery, a lithium ion battery also has these three elements. In general, lithium ion technology uses a liquid or inorganic colloidal electrolyte, so a strong outer casing is required to contain the flammable active ingredient, which increases the weight and cost of the battery, and also limits the size and shape flexibility. In general, the minimum thickness of a liquid lithium ion secondary battery is 6 mm, which is more difficult to reduce.

And the so-called polymer lithium ion battery is in the three main structure at least one or more than one use of polymer materials as its main battery system.

A new generation of polymer lithium ion battery has very high on the degree of polymerization of materialized, so the shape can be thin shape is changed (0.5 mm the thinnest) and arbitrary shape, arbitrary area, greatly improving the battery design flexibility, which can meet the needs of the product, made into any shape and the capacity of the battery. At the same time, polymer lithium ion battery energy per unit of a 50% increase over the current general lithium ion battery, its capacity, charge and discharge characteristics, safety, working temperature range, the cycle life and environmental performance, and so on are the lithium ion battery has greatly improved.

Currently on the market are mainly used by the secondary battery nickel metal hydride (Ni - MH) and lithium ion (Li - ion) two types. Mass production in the lithium ion battery has liquid lithium ion battery (LiB) and polymer lithium ion battery (LiP) two kinds. So in many cases, the battery on the Li -ion, must be a lithium-ion battery. But is not necessarily a liquid lithium ion battery, it is possible that the polymer lithium ion batteries.

Lithium ion battery is the improved product of lithium-ion batteries. Lithium batteries have long ago, but it is a kind of highly active (remember its position in the periodic table?)Metal, it is not safe when using, often burning during charging, burst, and then there is the modified lithium ion battery, joined the inhibit lithium active ingredients (such as cobalt, manganese, etc.) so that the lithium electricity real reached a safe, efficient, convenient, and old lithium batteries has been basically eliminated. As for how to distinguish them, will be able to identify from the battery logo, lithium batteries for Li, lithium ion battery for Li - ion. Now, laptops and mobile phones using the so-called "lithium battery", are lithium ion batteries.

Now on the market sales of liquid lithium ion batteries (LiB) in the case of the overcharge, easy to cause the relief valve to crack and the situation of the fire, it is very dangerous, so must add protection IC circuit in order to ensure the battery overcharge situations will not occur. And polymer lithium ion battery, this type of battery in terms of relative liquid lithium ion battery has good resistance to charge and discharge characteristics, therefore to protect plus IC circuit requirements may be extended appropriately. Moreover in terms of charging, polymer lithium ion battery can use IC constant current charging, and adopted by the lithium ion secondary battery CCCV (Constant Currert – Constant Voltage) compared to the time needed for charging way can shorten the waiting time of many.

The application of lithium batteries, mobile phone manufacturers

Although in recent years, almost all manufacturers have tended to use lithium ion battery, but the world each big mobile phone maker's choice of battery or have their own characteristics and habits, such as once in the same historical period.

Nokia: Ni-MH (NIMH) batteries, LIB (Liquid Lithium Ion) batteries, and LIP (Polymer Lithium Ion) batteries are not used.

Ericsson: the Ni - MH battery, LIB batteries, LIP.

MOTOROLA: the Ni - MH battery, LIB, not LIP cell.

It's not hard to find, from the earliest for the mobile use LiP, polymer lithium ion battery this Ericsson embody the essence of technology pioneer of his mobile phone. According to the information I find indicated that the polymer lithium ion battery main manufacturer for Japan's SONY, Panasonic, GS, etc. Several companies, production reached 21 million in 2000, only 50% were Ericsson mobile phone accessory. Today, in 2002, lithium-ion batteries have been widely used and popularized on other mobile phone manufacturers. However, in the use of polymer lithium-ion batteries, it is still far from being popularized among all mobile phone manufacturers' products, and it will take time to widely use them.

On the other hand, although lithium-ion batteries have many advantages, they also have disadvantages, such as high price and less charge and discharge times. Lithium batteries charge and discharge only 400-600 times, after special improvement of the product is only more than 800 times. Ni-MH batteries can be charged more than 700 times, and some good quality products can be charged and discharged up to 1200 times. In comparison, nickel-metal hydride batteries have longer life than lithium batteries. In addition, the price of nickel-metal hydride batteries is much lower than that of lithium batteries. And strictly speaking, lithium batteries also have a memory effect, but it’s very low, basically negligible.

From this point of view, there is currently no perfect battery.
