TÜV Rheinland South China Solar,ESS & Charging Advanced Tech Seminar

On May 31, the South China Light Storage and Charging Advanced Technology Seminar, hosted by TÜV Rheinland, was held in Shenzhen. This seminar gathered industry experts, technical elites, and business representatives to discuss innovations in light storage and charging technology, exploring green and sustainable development.

Lithium battery working principle and working temperature range

Lithium-ion batteries are rechargeable batteries that rely heavily on lithium ions moving between positive and negative electrodes. In the charging and discharging process, Li+ is embedded and disembedded back and forth between the two electrodes: when charging the battery, Li+ is disembedded from the positive electrode, through the electrolyte into the negative electrode, the negative electrode is in a lithium rich state; The opposite is true when discharging. Batteries containing lithium as electrodes are representative of modern high-performance batteries. When a battery is charged, lithium ions are formed in the positive electrode of the battery, and the resulting lithium ions travel through the electrolyte to the negative electrode. As the negative carbon layer structure, it has a lot of micropores, reaching the negative lithium ions embedded in the carbon layer of micropores, the more embedded lithium ions, the higher the charging capacity. Similarly, when a battery is discharged, the lithium ions embedded in the carbon layer of the negative electrode escape and travel back to the positive electrode. The more lithium ions returned to the positive electrode, the higher the discharge capacity. General lithium ion battery charging current is set between 0.2C and 1C, the greater the current, the faster the charge, and the greater the battery heating. What's more, too much current can't charge to full capacity, because the electrochemical reactions inside the battery take time. Just like pouring beer, if you pour it too fast, it will foam and become dissatisfied. Operating temperature range of lithium ion batteries Conventional lithium ion battery operating temperature: -20℃~60℃, but generally lower than 0℃ lithium ion battery performance will decline, discharge capacity will be reduced accordingly, so the full performance of lithium ion battery operating temperature, common is 0~40℃. Usually, the better the low temperature ability of low temperature polymer battery, the worse its high temperature performance, these two requirements are relatively contradictory. Charging requirements, lithium requirements in 0℃ above, otherwise often charged, battery damage is faster, there are safety issues, discharge generally in -20~60℃.   Lithium titanate (LTO) batteries operate effectively in a broad temperature range, from -40℃ to 60℃, maintaining performance in extreme cold and high heat, outperforming traditional lithium-ion batteries, which degrade significantly below 0℃ and can overheat above 40℃. LTO batteries excel in fast charging, safely handling high charge rates (up to 3C or more), allowing full charging in 20 minutes or less, unlike traditional lithium-ion batteries that risk damage or reduced capacity. Additionally, LTO batteries offer enhanced safety due to their stable chemistry and thermal stability, reducing the risk of fires or explosions even under extreme conditions. These features make LTO batteries ideal for applications requiring reliable performance in harsh environments, fast charging, and high safety standards, such as electric vehicles and emergency power supplies.

Classification and use of Lithium Ion Polymer Battery

Lithium ion batteries are classified into liquid lithium ion batteries and polymer lithium ion batteries, depending on the electrolyte used. The positive and negative electrode materials used in polymer lithium-ion batteries are the same as liquid lithium ions.

Prioritizing Safety and Quality: The Wise Energy Approach to Energy Storage Solutions

There are only two directions for energy storage safety: "zero accident" and "disaster". The safety design concept of Wise Energy's energy storage solutions is to focus more on early prevention rather than later protection. Under the quantifiable safety design concept, Wise Energy has built multi-dimensional safety technology for the entire product life cycle. New energy storage, mainly battery energy storage, is an important technology and basic equipment to ensure the safe and stable operation of new power systems. It is also an important support for achieving the "double carbon" goal. In recent years, the battery energy storage industry has grown rapidly, but the products are of varying quality, posing new safety and reliability challenges to the grid-connected operation of large-capacity battery energy storage systems. Energy storage involves the safety of life, property, and the safety of power system operation. It is a critical infrastructure, and the cost of trial and error is extremely high. Therefore, we cannot follow the old path of pursuing speed first and then pursuing quality. We must insist on high-quality development from the beginning. The development of new energy storage cannot be based on temporary gains but must be a long-term solution. Energy storage is for use, not for facade decoration. Moreover, as an infrastructure, one of the biggest characteristics of energy storage is that it needs to last for more than 10 or 20 years, and it must be able to operate safely, stably and with high quality in a variety of complex environments and application conditions. Although there are short-term challenges in the development of energy storage, as long as it can overcome the tests of quality, safety, and empirical evidence, there is a clear path forward. We hope that the industry can create an ecologically inclusive industrial platform to jointly promote the common development of energy storage in a wider range of scenarios and jointly build a reliable and sustainable energy storage industry.
