Types of Lithium Batteries

 


Classification by positive and negative materials

1. Lithium cobaltate battery

Due to the good molecular structure of lithium cobaltate chemical elements so the battery structure is stable, high storage capacity ratio, outstanding overall performance, but its security is poor and the cost is very high. Lithium cobalt acid battery is mainly used in small and medium-sized batteries, which are widely used in small and medium-sized laptops, touch screen cell phones, MP3/4, laptops and digital cameras, small and medium-sized electronic equipment and instruments. The comprehensive performance of lithium cobalt acid battery is outstanding, and the standard voltage is often 3.7V.


2. Lithium manganate batteries

Lithium manganese acid batteries can be discharged at a current of 20-30A, and have the appropriate heat buildup. The material cost of lithium manganate battery is low, safety and low temperature performance index is good. Since its material itself is not too stable and easy to decompose and produce gas, it is mostly used to mix with other materials to reduce the cost cost of electric cells. The cycle life of lithium manganate battery decays faster and is prone to bulge, and its high temperature performance index is poor and its life is relatively short. Its nominal voltage is 3.7 V. Lithium manganate batteries are mainly used in hardware tools accessories, medical devices, and their hybrid cars and new energy vehicles.


3. Lithium iron phosphate rechargeable batteries

Lithium phosphate has very good electrochemical safety performance and low resistance. In the completion of the entire process of charging and discharging, lithium iron phosphate rechargeable batteries inside the battery structure will not produce much change, but also will not occur violent explosions. Even in the event of a short circuit, overcharging, being collision and other unexpected situations, is still very safe.


Classification by internal structure of raw materials

1. Lithium metal batteries

Lithium metal batteries are usually used manganese dioxide as the battery cathode material, lithium metal or its alloy steel metal as the negative electrode material. Lithium metal battery is a rechargeable battery using non-aqueous electrolyte solution.


2. Lithium ion battery

Lithium ion battery is usually used lithium alloy steel metal oxide as the battery cathode material, graphite material as the negative electrode material. Lithium-ion battery is a rechargeable battery using non-aqueous electrolyte.


Classification by shell material

1. Steel-cased rechargeable batteries

The vast majority of battery manufacturers use steel as the battery shell material, because the physical stability of steel materials, pressure resistance is much higher than the aluminum shell material.


2. Aluminum Case Rechargeable Battery

Aluminum shell rechargeable batteries are divided into hard shell and soft shell. As for the positive electrode material, there are many kinds.


3. Polymer lithium battery

Polymer lithium battery shell is a class of polymer raw materials, most of them are silver-white. Lithium polymer batteries are mainly used in car electronic enterprise products (GPS positioning tracker battery, tire pressure detector battery, car recorder battery), shared bicycle, solar energy storage lights, ultra-low temperature walkie-talkies, etc.

How to Choose the Right Battery for Your Application: Alkaline vs. Ni-MH vs. Lithium-Ion Batteries

As battery technology continues to upgrade, you need to know which type of battery is best for your device/product. There are many different types of batteries used in a variety of applications. From lead-acid to lithium-ion polymer batteries, different types of batteries have different properties based on different chemistries. But how do you choose batteries for your appliances/products? To better understand batteries, let’s take a look at the three types of batteries: alkaline, NiMH, and lithium ion batteries respectively. Alkaline battery: Alkaline batteries use potassium hydroxide or sodium hydroxide as the standard electrolyte solution. The anode is made of zinc powder; the cathode consists of manganese dioxide. Alkaline batteries are disposable primary cells. Ni–MH (nickel metal hydride) battery : Ni-MH batteries are a type of rechargeable battery and an evolved version of Ñ ickel- Ç admium (nickel-cadmium) batteries use potassium hydroxide as the electrolyte. The positive elect...

The Best Solar Power Batteries On The Market

One of the best ways to reduce your reliance on fossil fuels is to use solar power. You'll want to consider buying a battery system that is designed for solar power in order to store excess electricity and use it at night, during cloudy days, or when the sun isn't shining.   How solar power batteries work   Solar power batteries are a great way to store solar energy. They work by converting sunlight into electricity. This electricity can then be used to power things like lights or electronics. Solar power batteries can be used in a number of ways. They can be used to store energy when there is not enough sunlight. They can also be used to power devices when there is too much sunlight.   Best Solar Power Batteries   Looking for the best solar power batteries on the market? You ’ ve come to the right place! In this article, we will discuss some of the top solar power batteries on the market today. So, whether you are looking for a backup battery or an investment, read ...

4 Ways to Lower Your Electric Bill For Energy-Efficient Battery

  With the ever-increasing price of energy, it is more important than ever to find ways to lower your electric bill and maximize your savings. On this page, you will find information about four different ways you can save money on your next electric bill.   Tips on battery maintenance and recycling   1) Check your battery's water levels and do not let it run below the first level. 2) If you have a solar panel, shut them off when they're not needed to reduce your electric bill. 3) Install fewer appliances that use more electricity such as plasma TVs and AC units. 4) Make sure your refrigerator is set to turn off every hour or two during the day so that it doesn't continuously use electricity while it sits unused.   How to reduce your energy costs   No matter where you live, there are ways to lower your energy bill. The first and most important step is to make sure that your home is as energy-efficient as possible. This can be done by making sure that rooms with t...
