What are the types of lithium-ion batteries? What are the characteristics of different kinds of lithium ion batteries?


Usually we say that the important power lithium batteries are iron phosphate lithium ion batteries, manganese lithium ion batteries, cobalt lithium ion batteries, and ternary lithium ion batteries.lithium ion battery assembly So, what are the types of lithium-ion batteries and what are their characteristics?

First, lithium-ion batteries according to the internal material lithium-ion batteries are usually divided into two categories

Lithium metal batteries: lithium metal batteries are generally the use of manganese dioxide as the positive material, lithium metal or its alloy metal as the negative material, the use of non-aqueous electrolyte solution batteries.

Lithium-ion batteries: Lithium-ion batteries are generally batteries that use lithium alloy metal oxides as the cathode material,battery cell machine graphite as the anode material, and a non-aqueous electrolyte.

Although lithium metal batteries have a high energy density, they cannot be used as lithium batteries for repeated use because they are not stable enough and cannot be recharged. Lithium-ion batteries have the ability to be recharged over and over again, so they are being developed as important lithium batteries.

Second, lithium-ion batteries by use

The first is digital lithium-ion batteries, that is, our daily use of cell phones, tablet computers, mobile power, etc. these are digital lithium-ion batteries.

The second is power lithium-ion batteries, some new energy electric vehicles, drones and other products of the battery.prismatic cell assembly These batteries require a large instantaneous current, digital batteries can not meet the instantaneous high current, so this type of battery is also called high rate battery, the price is more expensive than the digital battery.

Third, lithium-ion batteries according to the shell material points

Steel case battery, as the name suggests is a steel case.

Aluminum shell batteries, the same, the shell is made of aluminum.

Polymer lithium-ion batteries, is a polymer material, the shell is mostly silver, a few manufacturers do black.

Fourth, lithium-ion batteries by shape

Cylindrical lithium-ion batteries, this is used a lot, this way is generally used through the combination, the combination of less can be used directly as a digital technology products, such as early laptop computers, portable power supplies

Square lithium-ion batteries, most of these are polymer batteries, because the polymer ductility is very good, you can make a lot of shapes, length, width and height can be adjusted at will, most digital products are now using this type of battery.

Shaped lithium-ion battery, shaped lithium-ion battery consists of packaging film, positive pole piece, negative pole piece, insulating diaphragm, pole lugs and electrolyte, which is characterized by the shape of the battery pole set can be a regular or irregular geometric shapes, the negative terminal can be set in the same side or different side of the battery pole set respectively; Shaped lithium-ion batteries are mainly used in smartwatches, smart wristbands, smart rings, medical devices (healthcare), wireless headphones, AR/VR, smart cards, smart clothing (heated clothing, heated gloves, smart shoes), tracking devices, portable sensors, smart tags, miniature speakers, smart locks, the Internet of Things and other fields, shaped batteries are the product of large-scale differentiation of user demand, and people's needs with the development of technology is also changing, the near future shaped batteries will be with the continuous increase in people's needs Usher in explosive growth!

What connections do lithium-ion batteries have?

Lithium batteries are interconnected in a following way. I frequently used the term "erie connection" to describe the lithium battery's erie circuit. Example: If two batteries with a combined capacity of 200 Ah and 24 V are linked in series, the resulting output voltage is 48 V and 200 Ah.
