The lithium polymer battery makes the emergency starting power supply a necessary companion for travel
In recent years, the automotive emergency start power supply market made of lithium polymer batteries has grown rapidly. This battery is light in weight and small in size, which can be easily carried with one hand. It also integrates the function of inflator pump, as well as lighting functions such as flash, SOS signal light and LED light, and can also be used as a charging bank to power various electronic products. It makes the automobile emergency starting power supply become a very practical product.
In the past, automotive emergency start power batteries often use lead-acid batteries, so what is the reason for lithium polymer batteries to quickly replace lead-acid batteries, and quickly spread to automotive emergency start power?
First, lithium polymer batteries have significant advantages in terms of energy density and volume. Lithium polymer battery than lead-acid battery energy density increased by 1 to 2 times, can store more electricity in a smaller volume, the use of lithium polymer battery car emergency start power will be lighter, smaller, convenient for users to daily use and storage in the car, and even as a large charging bank to use. This energy density advantage can not only improve the portability of automobile emergency start power supply, but also save manufacturers‘ production and transportation costs.
Secondly, lithium polymer batteries have significant advantages in storage, charge-discharge performance and life. The self-discharge rate of lithium polymer batteries is 0.5%~3%/ month, which is less than 10-20% / month of lead-acid batteries. It can also be developed as a fast charge function with more than 1C, which can be quickly replenished and reused in the face of emergency situations. It is well known that the life of lithium polymer batteries is also much higher than that of lead-acid batteries.
Thanks to the use of lithium polymer batteries, the car starting power supply reduces the size and weight, and the design redundancy can integrate more practical functions, such as air pumps, LED lighting, USB charging, etc., to meet more emergency or daily use needs of users.
