Introduction to the advantages of liquid lithium ion batteries and polymer lithium ion batteries

Liquid lithium ion battery 1. The energy is relatively high. It has a high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries; 2. long lasting. The service life can reach more than 6 years. The battery 1C (100% DOD) charge and discharge with lithium iron phosphate as the positive electrode has a record of 10,000 times of use; 3. The rated voltage is high (the single working voltage is 3.7V or 3.2V). It is approximately equal to the series voltage of three nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient to form a battery power pack; lithium-ion batteries can be adjusted to 3.0V through a new type of lithium-ion battery voltage regulator technology, which is suitable for small appliances usage of. 4. With high power tolerance. Among them, the lithium iron phosphate lithium ion battery used in electric vehicles can reach 15-30C charge and discharge capacity, which is convenient for high-intensity start-up acceleration; 5. The self-discharge rate is very low. This is one of the most prominent advantages of the battery, which can generally be less than 1% per month, which is less than 1/20 of the nickel-hydrogen battery; 6. Lightweight. The weight under the same volume is about 1/6-1/5 of the lead-acid product; 7. High and low temperature adaptability is strong. It can be used in the environment of -20℃--60℃, after the process is processed, it can be used in the environment of -45℃; 8. Green. No matter it is produced, used or scrapped, it does not contain or present any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium. 9. Production basically does not consume water. It is very beneficial to our water shortage. Advantages of polymer lithium ion battery 1. Good discharge characteristics. Polymer batteries use gel electrolytes, which have stable discharge characteristics and a higher discharge platform than liquid electrolytes. The self-discharge is small, and its capacity loss is also small after being left for a long time. 2. Shape customization. The manufacturer is not limited to the standard shape, it can be economically made into a suitable size. Polymer batteries can add or reduce the thickness of the battery cell according to the needs of customers, and develop new battery cell models. They are cheap and have a short mold-opening cycle. Some can even be tailored to the shape of the mobile phone to make full use of the battery shell space and improve battery capacity. 3. Strong security. The polymer lithium ion battery uses aluminum-plastic soft packaging in structure, which is different from the metal shell of the liquid battery. Once a safety hazard occurs, the liquid battery is easy to explode, while the polymer battery can only blow up at best. 4. The cell voltage is high. Because polymer batteries use high-molecular materials, they can be made into a multi-layer combination in the cells to achieve high voltage, while the nominal capacity of lithium-ion battery cells is 3.6V. If you want to achieve high voltage in actual use, you need more Only a series of batteries can form an ideal high-voltage working platform. 5. Good conductivity. The solid electrolyte of polymer batteries has low ionic conductivity. At present, it is important to add some additives to make it a gel electrolyte to improve the conductivity. This is just a new addition of ionic conductivity, unlike the conductivity of lithium-ion batteries that maintain a stable value, and will not be affected by the quality of auxiliary materials. 6. Lightweight. The battery using polymer electrolyte does not require a metal shell as a protective outer packaging. The weight of the polymer battery is 40% lighter than the steel shell lithium battery of the same capacity specification, and 20% lighter than the aluminum shell battery. 7. large capacity. Polymer batteries have a capacity of 10-15% higher than steel shell batteries of the same size and 5-10% higher than aluminum shell batteries. They have become the first choice for color screen mobile phones and MMS mobile phones. Nowadays, most of the new color screen and MMS mobile phones on the market are also used Polymer batteries. 8. The internal resistance is small. The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. At present, the internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. Level in line with international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace nickel-hydrogen batteries. 9. Long life, no memory effect. Long life, its cycle life can reach more than 500 times in normal use. There is no memory effect, no need to empty the remaining power before charging, easy to use.
