LR41 battery

　　Which is better, lithium titanate battery or LR41 battery?

　　Currently, as far as power batteries are concerned, ternary lithium batteries, LR41 battery packs and lithium titanate batteries have been used in the electric vehicle industry. Lithium iron phosphate batteries are becoming more and more active in the electric bus market due to their stable safety factor, good high-temperature performance, and light weight. So which one is better, lithium titanate battery or LR41 battery?

　　Comparison between lithium titanate battery and LR41 battery:

　　Lithium titanate battery:

　　Lithium titanate battery is a lithium ion battery cathode material lithium titanate, which can be composed of lithium ion battery or lithium-ion battery, such as lithium iron phosphate, ternary material or lithium-ion battery. In addition, it can also be used as a lithium metal positive battery or a lithium aluminum alloy negative battery. Generally, lithium titanate batteries are easy to cause abdominal distension, which leads to the filler of the lithium battery and greatly reduces the electrical performance.

　　Advantages of lithium titanate batteries:

　　1. Good safety and reliability

　　The potential difference of lithium titanate is higher than that of pure lithium, so it is difficult to produce lithium dendrites and the charge and discharge voltage is stable. The results show that the safety factor of lithium titanate batteries is far greater than that of lithium-ion batteries.

　　2.Excellent fast charging performance

　　Compared with carbon battery cathode materials, lithium titanate batteries have a higher thermal diffusion coefficient for lithium-ion batteries and can charge polymer batteries. In addition to greatly shortening the battery charging time, it has less harm to the service life of the circulation system and the thermal resistance is also stronger. Lithium titanate batteries can be fully charged in ten minutes.

　　3. Long life cycle

　　The lithium titanate battery charging cycle system is more than 30,000 times the battery charging cycle system. After 10 years of development, it will be used as a power lithium battery for 20 years. Customers do not need to replace batteries in specific applications, and there is almost no increase in medium and late costs.

　　4.Excellent resistance to wide temperature range

　　Generally, pure electric vehicles will have problems when charging the battery at -10c. Lithium titanate batteries have good wide temperature resistance and durability. They can be charged normally at minus 50c to minus 60c, whether in the Arctic or in the In the southern heat zone, customers are concerned that the car's rechargeable battery heart stops working easily.

　　Based on the advantages of lithium titanate batteries, the basic construction and personnel costs of electric vehicle charging stations can be saved.

　　Disadvantages of lithium titanate battery:

　　Lithium titanate is used as the negative electrode of lithium titanate batteries, and its market share is very low.

　　Less energy, more costs. The low specific energy is due to the basic characteristics of the battery cathode material lithium titanate, which makes it difficult to improve the space.

　　It is difficult to substantiate the long-term use claims of lithium titanate batteries. Battery cathode materials, lithium battery electrolytes, separators, application temperatures, etc. also affect the number of battery cycles.

　　LR41 battery pack:

　　Lithium phosphate battery pack is a lithium-ion battery using lithium phosphate battery as the cathode material. Its characteristics are not precious raw materials such as cobalt, the raw materials are cheap, phosphorus and iron are abundant in the earth's resources, and it is not easy to feed. Its working conditions are moderate, with large net weight capacity (170mah/g), high discharge power, fast charging, long life, and high reliability in high-temperature and high-burning environments.

　　Advantages of LR41 battery pack:

　　Small size and light weight, the volume of lithium battery is 2/3, and the weight is only 1/3-1/4 of lead-acid battery.

　　The cycle life of lithium iron phosphate batteries is 1200-2000 times, while traditional lead-acid batteries are only 500-900 times.

　　The battery has good charging characteristics, the charging efficiency is as high as over 97%, and the charging efficiency is as high as about 80%.

　　The raw materials of lithium iron phosphate batteries do not contain heavy metals and non-ferrous metals, and are non-toxic. There is zero pollution in both production and application. There was no explosion or fire in tests such as puncture, extrusion molding, overcharge, and short circuit failure.

　　Memoryless rechargeable batteries can be charged anytime and anywhere.

　　The operating temperature range is wide, the maximum temperature of lithium phosphate battery is 350℃-500℃, and the maximum temperature of lead-acid battery is only 200℃.

　　Disadvantages of LR41 battery pack:

　　Lithium iron phosphate rechargeable batteries have shortcomings such as low vibration density and low compaction density, resulting in low specific energy of lithium batteries; high raw material manufacturing and rechargeable battery manufacturing costs, low rechargeable battery output rate, and poor product consistency; patent issues.

　　In the new energy vehicle industry, rechargeable batteries are usually found in lithium phosphate battery packs or lithium-ion batteries. The competitive advantage of the Silver Dragon buses recycled by Greek air conditioners in recent years is the unique lithium titanate battery. Chinese automakers are using more lithium-ion batteries and LR41 battery packs. Lithium titanate batteries have not yet been industrialized. Lithium titanate batteries have a high lithium titanate content (high product cost and high environmental humidity control), and cost about 9 yuan per watt hour, which is very different from lithium iron phosphate rechargeable batteries and lithium batteries of 3 yuan per watt hour.

　　The future market for lithium titanate batteries will be very limited indoor space. There are very few companies producing lithium titanate batteries, which will lead to a reduction in overall R&D investment in the industry chain. In the future, the technological development speed of LR41 battery packs will exceed that of lithium titanate batteries. Generally speaking, it is best to use LR41 battery packs for battery vehicles, with safety first.

　　Summary: Lithium titanate batteries and LR41 battery packs are two different types of lithium batteries. They use different raw materials and have different performances, both with advantages and disadvantages. Lithium iron phosphate batteries are relatively powerful. It is said that polymer lithium batteries have not exploded and have been involved in short-term safety incidents. However, this kind of LR41 battery has been on the market for a longer time and is more reliable.
