China's lithium battery industry has made significant advancements and holds a crucial position in the global market. However, the industry still faces numerous challenges, including drastic fluctuations in raw material prices within the supply chain, insufficient upstream and downstream industry connections, and unfair market competition.
In response to these challenges, the Chinese government has begun implementing a series of measures, such as promoting coordinated development within the industry, strengthening capacity and investment regulation, and enhancing product quality supervision, to ensure the healthy and stable growth of the lithium battery industry. Currently, three key elements determine the high-quality development of the lithium battery industry:
In the current lithium-ion battery industry, innovation and development of cathode materials are at the core of improving battery performance. Cathode materials directly impact the battery's energy density, safety, cycle life, and low-temperature performance, making them a focal point of battery technology research.
Ternary materials (such as NCM and NCA) and lithium iron phosphate (LiFePO) are the most mainstream cathode materials in the current market. Ternary materials are widely used in high-end electric vehicles due to their high energy density, while lithium iron phosphate, known for its cost advantages and high safety, is suitable for the mid-to-low-end market and energy storage applications.
With the continuous advancement of technology, the development of positive electrode materials focuses on improving energy density, enhancing safety performance, and extending battery life. For instance, high-nickel ternary positive electrode materials increase energy density by raising nickel content while reducing cobalt content to lower costs and environmental impact. However, this also leads to decreased electrode structure stability and thermal stability, resulting in reduced battery cycling stability. Therefore, further material innovation and process improvements are needed to ensure safety and long-term reliability.
Innovation in positive electrode materials is crucial for the development of the lithium-ion battery industry, not only for enhancing battery performance but also for influencing the overall market competitiveness and sustainable development of the industry. With the continuous emergence of new materials and technologies, the performance of lithium-ion batteries will continue to be optimized and enhanced.
Innovation in patented technology is key to driving industry development.
The development of the lithium-ion battery industry is driven by advancements in material technology and innovative patented technologies. In recent years, with the rapid growth of the new energy vehicle market, the demand for lithium-ion battery technology has reached a new peak, leading major battery manufacturers to increase research and development investments, striving to achieve leadership in battery performance, safety, cost, and patented technologies.
Patent data shows that patent activity in batteries and other energy storage technologies grew at an average annual rate of 14% from 2005 to 2018, four times the average level across all technology fields. This growth is primarily driven by advancements in rechargeable lithium-ion battery technology, especially in the consumer electronics and new energy vehicle sectors.
The demand for electric mobility has driven the development of high-performance lithium-ion technologies aimed at improving battery energy density, lifespan, charge/discharge rates, and low-temperature performance. Additionally, to better integrate renewable energy sources like wind and solar power into the power grid, advancements in energy storage battery technology have been promoted.
In the realm of patents, there has been a continuous increase in solid-state lithium-ion battery patent applications. Solid-state lithium-ion batteries are considered the future mainstream direction due to their advantages in safety, energy density, and wide temperature range operation.
According to publicly available patent application data, there are close to 1900 patent applications related to solid-state lithium-ion batteries, with over 1000 applications since 2020, accounting for over 50%. The annual application volume remains between 250-300 applications, showing a trend of increasing each year.
The development of the lithium-ion battery industry relies on continuous innovation in materials and processes, with innovative patented technologies playing a crucial role in this process. This not only drives technological advancements but also supports companies in maintaining a leading position in an increasingly competitive market. As market and technological demands evolve, this innovation activity is expected to accelerate further.
