With the global awareness of sustainable development and environmental protection and the rapid development of the new energy automobile industry, power lithium battery, as one of its core technologies, is gradually becoming a key force to promote the energy revolution. This article will discuss the working principle of power lithium batteries, market status, challenges and future development trends.

How it works

Power lithium battery is a chemical power source that uses lithium metal or lithium compounds as negative electrode materials to achieve energy storage and release through the insertion and removal of lithium ions. Its basic composition includes positive electrode, negative electrode, diaphragm and electrolyte. During operation, lithium ions travel back and forth between the positive and negative electrodes in the charge and discharge cycle, along with the external circuit flow of electrons, thus generating current. This working mechanism makes the lithium battery have the advantages of high energy density, no memory effect, and long cycle life.

Market situation

At present, the power lithium battery market is in a stage of rapid development. According to market research institutions, the installed capacity of global power lithium batteries continues to grow, especially in the field of electric vehicles, which has become the main growth point of the lithium battery market. China, as the world's largest market for new energy vehicles, has a particularly strong demand for power lithium batteries. At the same time, policy support and consumer environmental awareness in Europe, North America and other regions have also promoted the expansion of the power lithium battery market.

Facing challenges

Although the power lithium battery market has broad prospects, its development still faces many challenges. The first is the safety issue, because the lithium battery in the overcharge, overdischarge, high temperature and other conditions there is a risk of thermal runaway, so improve the safety performance of the battery is the industry needs to solve the problem. While the cost of lithium batteries has dropped significantly in recent years, the overall cost of electric vehicles is still high relative to conventional fuel vehicles, which limits the speed of their adoption in the market. In addition, the instability of raw material supply and environmental pollution are also factors restricting the development of power lithium batteries.
