USE LITHIUM-ION BATTERIES TO IMPROVE UPS

Because lithium-ion batteries have higher power density and lighter weight than lead-acid batteries, data center operators can switch to this smaller, lighter UPS Lithium-ion Battery System.

Many businesses today rely on data centers for their business and digital functions. They are becoming more and more important to businesses for a number of reasons, such as streaming video services, processing customer transactions, providing employees with cloud computing, and running e-commerce sites.

UPS Lithium-ion Battery System

So, as one might imagine, any downtime can be very expensive for the business. For e-commerce sites, new production information or tracking sales can be difficult, and the problem can be just irritating because employees can't access the files they need. In addition, they could have serious financial implications, such as a British Airways blackout in May 2017. Power outages at Heathrow's data center caused British Airways flight 726 to be cancelled, and many passengers' luggage was lost, resulting in direct economic damage of $ 108 million and reputational damage. Therefore, a well-designed UPS (uninterruptible power supply) is used in conjunction with an advanced battery system to ensure that even if a power problem occurs, its operation can be continued without downtime.

The UPS power supply system uses the battery to provide uninterrupted power in the event of a power outage until it switches to a standby diesel generator to start or safely shut down the equipment. UPS power can also act as a power conditioner by absorbing or injecting power to overcome short-term spikes and voltage drops in utility power. These are usually caused by voltage transients when other large grid-connected load equipment is turned on and off.

There are many reasons for this. One of them is the higher power density and higher energy density of lithium-ion batteries, which can provide more power while reducing floor space and weight. Compared with lead-acid batteries, lithium-ion batteries can be three times smaller and six times lighter. In addition, it has a higher cycle life than other battery technologies, which means it has a longer life. In addition, lithium-ion batteries work more reliably at higher temperatures and require less cooling, which reduces battery footprint.

Although there are several types of lithium-ion batteries, lithium iron phosphate batteries are suitable for industrial and mission-critical applications that focus on safety, power density, and operating life. Lithium-Ion Battery Energy Storage System has the advantages of high availability, low maintenance requirements, and fast discharge. This minimizes the risk of unexpected data center outages.

Applications that require higher operating temperatures are best suited for lithium-ion batteries because they can withstand higher temperatures than lead-acid batteries. As a result, data center operators will need less power to cool, helping to reduce their power efficiency.

Lithium-ion batteries can operate at 35°C for best performance for up to 20 years. However, under the same environmental conditions, lead-acid batteries will shorten the operating life and reduce performance, so cooling equipment is required to cool them. Therefore, by adopting a lithium-ion battery system, the power of air-conditioning equipment can be reduced, electricity costs can be reduced, and energy consumption can be reduced during the life of the battery, thereby reducing operating costs.

Lithium-ion batteries are now widely used in everyday life, from mobile phones and computers to megawatt-level energy storage in grid stabilization and solar applications. They are everywhere. Applications in data centers require less space, smarter equipment, longer uptime, and optimization of the entire ecosystem, including air conditioning in the computer room. With the increasing use of lithium-ion batteries and the continuous improvement and growth of key requirements, lithium-ion batteries can meet the needs of today and tomorrow's data centers.

The above is the advantages of lithium-ion batteries in UPS introduced by UPS Lithium-ion Battery System Supplier.

WHICH LITHIUM-ION BATTERY AND LEAD-ACID BATTERY ARE MORE SUITABLE FOR HOME ENERGY STORAGE SYSTEMS?

According to foreign media reports, in the past, most residential solar users deploying battery energy storage systems used lead-acid batteries, especially batteries that were completely off the grid. However, this situation has started to change in the past few years. Lithium batteries are increasingly used in residential energy storage systems. So, which of the lithium-ion and lead-acid batteries is more suitable for energy storage systems? The following are the advantages and disadvantages of Lithium Iron Phosphate Battery Manufacturer.

1. Application of lead-acid battery

Since the 1970s, lead-acid batteries have been used as a backup power source for residential solar power generation facilities. Although they are similar to traditional automotive batteries, batteries used in residential energy storage systems are called deep-cycle batteries because they are discharged and recharged more often than most automotive batteries.

Traditionally, lead-acid batteries cost less than lithium-ion batteries, which makes them more attractive to residential users. However, they have a much shorter operating life than lithium-ion batteries.

Comparison of cycle life of lead-acid batteries and lithium-ion batteries in fixed energy storage systems

The operating life of lead-acid batteries is lower than that of lithium-ion batteries. Although some lead-acid batteries can be charged and discharged up to 1,000 times, lithium-ion batteries can be charged and discharged between 1,000 and 4,000 times.

Most lead-acid batteries have a service life of about 5 years and have a corresponding warranty period. As a result, residential users will have to replace lead-acid batteries multiple times throughout the life of a solar power facility.

The storage efficiency of lead-acid batteries is lower than other energy storage technologies such as lithium-ion batteries. Due to their low efficiency, they also cannot be charged or discharged as quickly as lithium battery energy storage systems.

Lead-acid batteries have a low discharge capacity, which means that consuming too much energy can quickly deteriorate their ability to store energy. Because lead-acid batteries have relatively low energy storage efficiency and cannot be fully discharged, lead-acid batteries require more energy storage capacity and space than lithium-ion batteries. Lead-acid batteries are also much heavier than lithium-ion batteries. Placing lead-acid batteries requires a stronger support and more space than lithium-ion batteries.

Lead is a toxic heavy metal. Although it is recyclable, it can still be contaminated by improper handling.

2. Application of lithium ion battery

Lithium-ion batteries are quickly becoming the battery of choice for many power applications, from wireless power tools to laptops and vehicles. More and more residential solar power facilities use lithium-ion battery energy storage systems. However, lithium-ion batteries still have some limitations. The first and most important point is the high cost.

The up-front cost of lithium-ion batteries is higher than that of lead-acid batteries. But the cost of lithium-ion batteries is rapidly falling. It is important to understand the cost of lithium-ion and lead-acid batteries currently used in residential energy storage systems. They can be used either as stand-alone energy storage systems or in conjunction with residential solar power facilities to meet the energy needs of some or all residential users or businesses.

Lithium-Ion Battery Energy Storage Systems

In terms of working life, Lithium-Ion Battery Energy Storage Systems are expected to continue to operate for about 10 years, and they can charge and discharge to higher levels without significantly reducing capacity. Lithium-ion batteries can also be charged faster at higher voltages. Although lead-acid batteries can take up to 16 hours to fully charge, even the slowest-charging lithium-ion batteries can be fully charged in about four hours. In terms of weight. Lithium-ion batteries used in residential energy storage systems are not light, but are much lighter than lead-acid storage.

All in all, lithium-ion batteries have more advantages in energy storage applications than lead-acid batteries, and as costs decrease, they will become more and more widely used in energy storage systems.

Lithium Iron Phosphate Battery Working Principle and Advantages

At present, power batteries mainly include lithium iron phosphate batteries, lithium manganate batteries and ternary lithium batteries. The lithium iron phosphate battery supports half of the lithium ion battery material industry. What is the working principle of the lithium iron phosphate battery? Next Lithium Iron Phosphate Battery Manufacturer will come to tell you.

The positive electrode of the lithium iron phosphate battery is composed of LiFePO4 with an olivine structure, the negative electrode is composed of graphite, and the middle is a polyolefin PP / PE / PP separator.

During charging, lithium ions are de-intercalated from the positive electrode through the electrolyte into the negative electrode. At the same time, electrons are moved from the positive circuit to the negative electrode from the external circuit to ensure the charge balance of the positive and negative electrodes. During discharge, lithium ions are de-intercalated from the negative electrode and inserted into the positive electrode through the electrolyte. The charging and discharging voltage platform of the lithium iron phosphate battery is long and stable. The lithium iron phosphate battery shows good cycle stability during charging and discharging, and has a long cycle life.

Lithium-Ion Battery Energy Storage System

So what are the advantages of lithium iron phosphate batteries?

Lithium Iron Phosphate Battery has won the trust of many manufacturers due to its low price and strong security. The positive electrode material in lithium-ion batteries accounts for more than 40% of the total battery cost. Under the current technical conditions, the energy density of the overall battery mainly depends on the positive electrode material. Therefore, the positive electrode material is the core development and research material for lithium-ion batteries, and is currently mature. Applied cathode materials include lithium cobaltate, lithium nickel cobalt manganate, lithium iron phosphate, and lithium manganate.

1. Lithium cobaltate

There are layered structure and spinel structure. Generally, layered structure is commonly used. The layered structure of lithium cobaltate is mainly used in digital products such as mobile phones, aircraft models, car models, electronic cigarettes, and smart wear. At present, the energy density and compaction density of lithium cobaltate have basically reached the limit. Compared with the theoretical capacity, there is still a large room for improvement. However, due to the limitations of the current overall chemical system, especially the electrolyte system at high voltage It is easy to decompose, so the method of further increasing the specific capacity by increasing the charge cut-off voltage is subject to certain restrictions. Once the subsequent breakthrough in the electrolyte technology, there will be room for improvement in its energy density.

2. Nickel cobalt cobalt manganate

The current research on single crystal nickel cobalt cobalt manganate mainly improves the energy density of the product by continuously increasing the nickel content and increasing the charge cut-off voltage. Capabilities put forward higher requirements.

3. lithium manganate

There are spinel structure and layered structure, spinel structure is commonly used. It has the characteristics of better capacity, stable structure, superior low temperature performance and low cost. However, its crystal structure is easily distorted, resulting in capacity attenuation and short cycle life. It is mainly used in some markets with higher safety requirements and high cost requirements, but lower energy density and cycle requirements. Such as small communication equipment, power bank, power tools and electric bicycles, special scenarios (such as coal mines).

4.lithium iron phosphate

Generally has a stable olivine skeleton structure, the discharge capacity can reach more than 95% of the theoretical discharge capacity, excellent safety performance, good resistance to overcharge, long cycle life, and low price. Lithium iron phosphate cathode material shows good thermal stability, safety and reliability, low carbon and environmental protection when applied. It is the first choice cathode material for Lithium-Ion Battery Energy Storage System.
