Lithium-ion batteries are in everything from cell phones to cars. However, recent incidents involving fires or explosions of these devices show there's a need for safer batteries. One option is to replace the flammable liquid electrolyte with a solid-state electrolyte (SSE). But some of the most-studied SSEs are themselves flammable, leaving the original safety concern unaddressed. Researchers now report in ACS' Nano Letters that they have developed an SSE that won't burn up.

Lithium-ion batteries have been the most favorable and adored battery technology for decades now supporting and powering the growth and development of technology all over the world. These batteries come in a variety of shapes, sizes, and types that are designed to be applied in almost every area that requires a sustainable and reliable energy source. From the standard lithium-ion batteries, lithium-polymer cells to the famous 18650 lithium batteries, and many others, lithium-ion based cells have proven to be man's best companion when it comes to energy solutions towards achieving a clean and rechargeable future that everyone would be proud of.

The safety of lithium batteries and lead-acid batteries has always been a point of controversy among users. Some people say that lithium batteries are safer than lead-acid batteries, but others think the opposite. From the perspective of battery structure, the current lithium battery packs are basically 18650 batteries for packaging, and lead-acid batteries are basically maintenance-free lead-acid batteries with good sealing performance, and the risk factors of the two are basically the same. Who is safer, just look down and you will know!

During the use of lithium-ion rechargeable batteries, overcharge, overdischarge, and overcurrent will affect battery life, performance, and safety. The fuse in the rechargeable battery acts as a secondary overcurrent protection in conjunction with the IC control loop to effectively monitor and prevent battery damage. Cause damage.

Lithium-ion battery is a widely used rechargeable battery. It has high operating voltage, small size, light weight, high energy density, long cycle life, can be fully charged quickly in a short time, and allows discharge temperature Wide advantages. In addition, lithium-ion batteries have the advantages of low self-discharge current, no memory effect, and no environmental pollution. Its global supply is continuously increasing.

Lithium-ion batteries, as a new generation of rechargeable power sources, have the advantages of long cycle life, large volume density, high operating voltage, high safety performance, and wide operating temperature range. They are the mainstream development direction of current rechargeable batteries. It also has the characteristics of low maintenance requirements and no memory effect. It can be charged and discharged at any time during the battle, and requires almost no battlefield maintenance, reducing logistical burden. Therefore, it has been valued and developed by the military of all countries. In recent years, lithium-ion batteries have been widely used in military equipment such as individual combat systems, submarines, unmanned aerial vehicles, and aerospace vehicles, and have shown broad application prospects in land, sea, air, and space.

Lithium battery maintenance methods, how to maintain lithium batteries in winter? Lithium batteries are easy to enter the market due to their advantages of compactness, lightness and environmental protection. The heavy, short life and heavy pollution lead-acid batteries can no longer meet our needs. The lithium battery has been cured, and it can be used for 5-7 years. Good maintenance habits can greatly help extend the life of your lithium battery. What are the precautions for lithium battery maintenance? How to maintain the lithium battery in winter? Lithium battery manufacturers will answer your questions below.

The working principle of lithium battery discharge, what is the cut-off voltage? The termination voltage of lithium battery discharge means that after the lithium battery is discharged to a certain voltage, it should not be continued to discharge, otherwise it will cause irreversible loss of some of the lithium battery ’s power and serious damage to the battery. The nominal voltage of a single lithium battery is generally 3.7V, and the termination voltage is 2.75V.

Batteries packed in aluminum cases are sealed with laser sealing technology and fully sealed. The aluminum case technology is very mature, and the material technology, such as the inflation rate, expansion rate and other indicators, is not high.

The LiFePO4 battery has the advantages of high working voltage, large energy density, long cycle life, good safety performance, small self-discharge rate, and no memory effect.
