PB battery application and maintenance

accord21 accord21

Mar 14, 2024 - 10:16 AM

PB cells, called the lead-acid Battery (Lead - Acid ’), is a kind of common chemical power source. It is composed of a positive plate, a negative plate, an electrolyte, a separator and a battery housing. PB battery uses lead and its alloy material as the active substance, with sulfuric acid as the electrolyte, has a high energy density and stable output performance.
Europe is one of the leading continents in utilising Li-ion batteries in multiple applications, including stationary energy storage, rail, marine, truck and automotive. For the energy storage market in particular, the leading countries for the deployment of LiIon batteries are: Italy for T&D grid support, Germany for PV self-consumption, and France in the island grids. Most suppliers of Li-Ion batteries are from Asia (Korea, China and Japan), but there are several European manufacturers of Li-Ion batteries and grid-connected Li-Ion storage systems. The other main European players are the so-called integrators that integrate Li-Ion battery modules from different battery suppliers together with inverters and control systems.

1. Positive plate: The positive plate is usually made of lead-calcium alloy material, and the surface is attached with lead oxide, which is used as the active substance when the battery is discharged.

2. Negative plate: The negative plate is made of lead-antimony alloy material, and the surface is attached with reduced lead, which is used as the active substance when the battery is charged.

3. Electrolyte: electrolyte is an important part of PB battery, mainly composed of sulfuric acid and water mixed in a certain proportion. In the process of battery charging and discharging, the electrolyte plays the role of transferring charge and maintaining the stability of the internal pressure of the battery.

4. Partition board: The partition board is used to isolate positive and negative plates, prevent short circuit, and allow the electrolyte to flow between the positive and negative plates.

5. Battery shell: The battery shell is used to hold the internal components of the battery and play a protective role. Battery housings are usually made of corrosion-resistant, high-strength materials.

6. Valve control system: The valve control system is a key part of the PB battery, which can effectively prevent the battery from overcharging and overdischarging, and ensure the safe and stable operation of the battery pack.

3.7V lithium ion battery is a typical single voltage battery, its operating voltage is usually 3.7 volts, fully charged voltage can reach 4.2 volts. Because of its high voltage and high energy density, it has become the preferred power supply for many portable electronic product designs. The 3.7V lithium-ion battery, with its excellent charging life, can support the device for a long time, which is particularly critical for mobile communications and portable media playback devices. In addition, this type of battery also has good safety performance, can prevent overcharge, overdischarge and short circuit may cause safety problems under decisive safety protection measures.

3.7V lithium ion battery in the market application
3.7V lithium ion battery in the market application is very wide, covering mobile communications, personal computers and tablet devices, digital cameras, portable media players and other fields. As people’s dependence on mobile devices continues to increase, the demand for lithium-ion batteries continues to rise. In particular, the rapid growth of the smartphone market is driving the demand for high-performance lithium-ion batteries due to users’ higher expectations for battery life. In addition to conventional consumer electronics, 3.7V lithium-ion batteries are also used in drones, smart wearables, smart home devices, and certain power tools. With the advancement of science and technology, the rapid development of these areas will further expand the market size of 3.7V lithium-ion batteries. In the future, with the popularization of Internet of Things (IoT) technology and 5G communication technology, and the introduction of more smart devices, the demand for small, high energy density lithium-ion batteries is expected to continue to grow.

Market development trend of 3.7V lithium-ion batteries https://www.accord-power.com
Market research reports show that the market demand for 3.7V lithium-ion batteries will continue to grow in the next few years. This growth is being driven by a number of factors. First, the pursuit of longer battery life in mobile communications and computing devices has not diminished, but has become more urgent as the capabilities of devices continue to increase. In addition, the wide adoption of emerging markets has also had a positive impact on the battery market.

With the global awareness of sustainable energy and environmental protection, the rapid development of electric vehicles and energy storage systems will also have a significant impact on the 3.7V lithium-ion battery market. Although these applications may use battery packs with larger capacity and higher output voltage, there is still a lot of opportunity to use 3.7V single lithium-ion batteries in battery management systems, modular design, and so on.

Characteristics and application of automotive lead-acid batteries

accord21 accord21

Mar 14, 2024 - 10:12 AM

Automotive lead-acid batteries are a traditional type of batteries with mature production technology and a wide range of applications. Its advantages are mainly manifested in the lower cost, mature production and recycling channels, and relatively small pollution of the environment. And one of the most representative products is the starter-lighting-ignition (SLI) lead-acid battery, which is mainly used for automobile starting and electrical system power supply.

The basic structure of a lead-acid battery consists of a positive and negative plate, an electrolyte, and a partition. The positive plate is mainly composed of lead dioxide, while the negative plate is spongy lead. During discharge, the lead compounds on the positive and negative plates are converted to lead sulfate, and during charging they are converted back to their original substance.

Despite the advantages of lead-acid batteries such as low cost, they also have a number of shortcomings, such as lower energy density, limited cycle life (typically 300-500 cycles) and heavier weight. In addition, lead-acid batteries perform poorly in extreme temperatures, require regular maintenance, and have problems with possible damage from over-discharge.

The advantages of lithium batteries in the automotive field
Lithium batteries are a new type of batteries that have been developing rapidly in the automotive field in recent years, which use lithium metal or lithium alloy as the anode material, and a non-aqueous electrolyte. The advantages of lithium battery are high energy density, light weight, long cycle life and excellent high and low temperature performance.

Lithium batteries have more than three times the energy density of lead-acid batteries, which means that lithium batteries are capable of storing more electrical energy in the same volume or weight. Lithium batteries typically have a cycle life of more than 1,000 cycles, and many high-quality lithium batteries can even reach more than 5,000 cycles. The lighter weight also allows lithium batteries to be widely used in electric vehicles where weight reduction is required.

In addition, lithium batteries charge and discharge faster, and there is no memory effect, simplifying the maintenance process. Moreover, lithium batteries have a wider operating temperature range than lead-acid batteries, resulting in better environmental adaptability. In terms of environmental protection, lithium batteries do not contain heavy metals and harmful substances, more in line with contemporary green requirements. https://www.accord-power.com
