Lithium battery 8 amazing advantages

Advantages of lithium battery

Understanding the basic knowledge of lithium ion batteries is key to designing more efficient electric vehicles.

The lithium battery has a high voltage platform. The average voltage of a single battery is 3.7V or 3.2V, which is approximately equal to the series voltage of three nickel-cadmium batteries or nickel-metal hydride batteries, making it easy to form a battery power pack.

Compared with batteries, lithium batteries have high energy density. It has high storage energy density, currently reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.

Compared with lead-acid batteries, lithium batteries are lightweight and weigh about 1/5-6 of lead-acid products in the same volume.

The service life of lithium battery is relatively long, and the service life can reach more than 6 years. The battery with lithium iron phosphate as the positive electrode can be charged and discharged with 1CDOD, and there is a record of being used 1,000 times.

It has high power endurance, among which the lithium iron phosphate lithium-ion battery used in electric vehicles can reach a charge and discharge capacity of 15-30C, which facilitates high-intensity starting and acceleration.

It has low self-discharge rate and no memory effect, and is often used to power daily electronic products.

Lithium battery has strong adaptability to high and low temperatures and can be used in the environment of -20℃–60℃. After processing, it can be used in the environment of -45℃.

Green and environmentally friendly, it does not contain or produce any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances regardless of production, use and disposal.The application of lithium ion battery technology has revolutionized portable electronics, enabling smartphones to stay powered for longer periods without needing frequent recharging.

Disadvantages of lithium battery

One of the disadvantages of lithium ion batteries is their potential for thermal runaway, which can lead to overheating and even combustion in certain conditions.

Lithium batteries have poor safety and are in danger of explosion.

Lithium batteries made of lithium cobalt oxide cannot discharge at high currents and are less safe.

Lithium batteries need to protect the circuit to prevent the battery from being overcharged or discharged.

The production requirements are high and the cost is high.

How to choose lithium battery

Look at the appearance

Looking at the appearance refers to looking at the appearance, workmanship, size and craftsmanship of the lithium battery. Check whether the seams of the shell are wide, whether there are burrs, whether there are oil stains, and whether it feels good to the touch. The advanced technology is very comfortable to the touch. After polishing, the rubber oil polished material not only feels good, but also has strong insulation properties.

Check whether the capacity is clearly marked

A lithium battery without clearly marked capacity is likely to be a junk battery reassembled using inferior battery cells or recycled battery cells. There are many cheap lithium batteries on the market, which are made of recycled battery cells or disassembled battery cells. Although the price is cheap, the lifespan is short and the quality is unstable. Careless use may damage the device or even explode.

Look at the protection circuit

The characteristics of the lithium battery determine that the lithium battery must be equipped with a protective plate to prevent the lithium battery from overcharging, over-discharging, short-circuiting, etc. A lithium battery without a protective plate will be in danger of deformation, leakage, and explosion. Under fierce price competition, various battery packaging manufacturers seek lower-priced protection circuits, or simply omit this device, leaving the market flooded with lithium batteries that are in danger of explosion. Of course, in fact, consumers cannot tell whether there is a protective circuit board from the appearance, so it is best to choose a reputable merchant to buy.

Look at the brand

There are many brands of lithium batteries, but the quality is difficult to tell from the appearance. In this case, everyone should do more homework before choosing and check the manufacturer’s information online. Generally speaking, professional manufacturers are more reliable than small workshops, and manufacturers that have been in business for a long time are more trustworthy than those who have just entered the field.
