Project background
The Internet of Things is transforming logistics and supply chain management. Innovation is taking place at the sensor level and network level connected to goods and assets, capturing and transmitting data all the way from the production line to the final delivery point, so battery life will be a key factor in matching this trend. The pulse power required for signal communication from the circuit to the end user is usually above 10s 2 amperes at various temperatures and even extreme temperatures around the world.
Traditional lithium-ion batteries can not meet the requirements due to the lack of peak current output and large capacity loss at extremely low or high temperatures, and their service life will be significantly shortened. The commercially available lithium thionyl chloride battery (Li-Socl2) is one of the longest-lasting primary batteries on the market.However, when you use batteries alone for high-pulse applications, you will face the problem of their power limits. The battery can discharge only a few tens of milliamps of low power. If forced to draw power from the battery, will damage the battery, shorten the service life. Therefore, in order to make a complementary choice for the long life power supply scheme, this project will focus on the development and design of battery materials to develop the type HPC1520 rechargeable lithium ion battery with long cycle performance and excellent extreme temperature performance. Combined with the commercially available ER26500 lithium sulfurous chloride batteries, the HPC1520+ER126500 battery pack can provide sufficient pulse power output under normal or extreme temperatures, and has a long cycle life.
