Lithium battery is an important part of the power battery. Under the development of the battery management system, the lithium battery market has developed rapidly and occupied an important seat in the power battery market. At present, the batteries commonly used in power batteries are lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, solar cells, vanadium batteries and fuel cells. Power batteries are widely used in electric bicycles, electronic products, new energy vehicles and photovoltaic power generation. In recent years, driven by the continuous development of the downstream market, the battery market demand has grown steadily, and the overall development of the industry is improving. In the development of battery systems, the sampling of MICROHM's precision alloy shunts can improve the utilization rate of power batteries, which promotes new energy vehicles power batteries are widely used.

The market for lithium batteries in power batteries is also expanding rapidly year by year. In 2017, the sales revenue of lithium batteries in China has exceeded 150 billion yuan. In the future, driven by power batteries, it is estimated that the sales revenue of lithium batteries will exceed 200 billion yuan in 2019, and will cross the 300 billion yuan mark in 2021.
 
Taking lithium batteries as an example, under the vigorous promotion of new energy vehicles and the accelerated popularization of digital electronic products, the output of lithium batteries in China has increased substantially, and it has become one of the fastest growing markets for lithium-ion batteries worldwide. As of the end of October 2018, the national lithium battery production reached 11.39 billion, exceeding the total output of 11.113 billion in 2017.


Although lithium batteries have developed rapidly, they have high cost and unsatisfactory product performance, especially battery stability, safety, charge and discharge time, and endurance, which have certain inhibition on the development of lithium-ion batteries. At present, lithium-ion batteries mainly improve the specific energy density, specific energy and other aspects to improve battery performance, which requires continuous technical input and progress of lithium-ion batteries, which also means that lithium batteries have much room for improvement in the future.

Although the overall development of the power battery industry is good, there are also some market segments that are under pressure. For example, if there is a highly polluting lead-acid battery, many policies carry out environmental protection actions and pay more attention to green safety. In terms of power battery development, it is also very urgent to reduce the environmental pollution to provide battery recycling. In the future, the battery will be more developed in the battery management system BMS and power management system. This will also promote the performance of various components of the power battery, such as current sensing resistors.
