The lithium battery industry in mainland China has made significant progress and occupies an important position in the global market. However, the lithium battery industry still faces a large number of challenges, including the sharp fluctuation of raw material prices in the supply chain, the lack of links between upstream and downstream industries, and unfair market competition. In response to these challenges, the mainland government has begun to take a series of measures, such as promoting the coordinated development of the industry, strengthening production capacity and investment supervision, and improving product quality supervision to ensure the healthy and stable development of the lithium battery industry. At present, there are three main factors that can determine the high-quality development of the lithium battery industry:
The development of cathode materials is the core of improving the performance of batteries
In the current lithium-ion battery industry, the innovation and development of cathode materials is the core to improve battery performance. Cathode materials directly affect the energy density, safety, cycle life and low-temperature performance of batteries, so they have become a hot spot in battery technology research.
Ternary materials (such as NCM and NCA) and lithium iron phosphate (LiFePO₄) are the most mainstream cathode materials on the market today. Ternary materials are widely used in high-end electric vehicles due to their high energy density, while lithium iron phosphate is suitable for low-end markets and energy storage due to its cost advantage and high safety.

With the continuous advancement of technology, the development of cathode materials is mainly focused on increasing energy density, improving safety performance, and extending battery life. For example, high-nickel ternary cathode materials increase energy density by increasing nickel content while decreasing cobalt content to reduce cost and environmental impact. However, this also leads to poor electrode structure stability and thermal stability, and a decrease in battery cycle stability. Therefore, further material innovation and process improvement are needed to ensure its safety and long-term reliability.
The innovation of cathode materials is crucial to the development of the lithium-ion battery industry, which is not only related to the improvement of battery performance, but also affects the market competitiveness and sustainable development of the entire industry. With the continuous emergence of new materials and technologies, the performance of lithium-ion batteries will continue to be optimized and improved.
The innovation of patented technology is the key to promoting the development of the industry
The development of the lithium-ion battery industry is driven by the progress of material technology and the innovation of patented technology. In recent years, with the rapid development of the new energy vehicle market, the demand for lithium-ion battery technology has entered a new peak period, and major battery manufacturers have increased R&D investment and competed to take the lead in battery performance, safety, cost and patented technology.
Patent data shows that patent activity for batteries and other power storage technologies grew at an average annual rate of 14% between 2005 and 2018, four times the average for all technology sectors. This growth is primarily driven by advancements in rechargeable lithium-ion battery technology, particularly in the consumer electronics and new energy vehicle segments.
The demand for e-mobility has led to the development of high-performance lithium-ion technologies aimed at improving the energy density, service life, charge-discharge speed, and low-temperature performance of batteries. In addition, advances in energy storage battery technology have been facilitated by the better integration of renewable energy sources such as wind and solar into the power grid.

In the field of patents, the number of patent applications for solid-state lithium-ion batteries continues to increase: Solid-state lithium-ion batteries are considered to be the mainstream development direction in the future because of their advantages in safety, energy density, and wide temperature range operation. According to the published patent application data, the patent applications for solid-state lithium-ion batteries are close to 1,900, and since 2020, the number of patent applications for solid-state lithium-ion batteries has exceeded 1,000, accounting for more than 50%, and the average annual number of applications has remained between 250-300, and it is increasing year by year.
The development of the lithium-ion battery industry relies on continuous innovation in materials and processes, and the innovation of patented technologies plays a key role in this process, which not only drives technological progress, but also supports companies to ensure their leading position in an increasingly competitive market. This innovative activity is expected to continue to accelerate as market and technology needs evolve.
The optimization of talent layout is a strategy for sustainable development
The lithium battery industry in mainland China is in a stage of rapid development, so the talent layout is very important. Some strategies for the layout of materials science such as lithium battery in Chinese:
1. Scientific and technological achievements drive productivity
Enterprises should closely focus on the research and development of new technologies, new materials and new products to create high-quality products and advanced technologies, which not only improve market competitiveness, but also the key to attracting and retaining talents.
2. Introduce and nurture top talents
Enterprises should actively introduce high-end talents and cultivate local talents at the same time. Some pioneers in the domestic battery industry have successfully introduced a number of domestic and foreign experts, setting an example for battery companies.
3. Establish a talent training and evaluation mechanism
Plan and sort out the relevant positions in the lithium battery industry, classify and formulate talent standards in the field of lithium batteries and other materials, and establish a standardized talent training and evaluation mechanism to ensure the quality of talents.
4. Retain talent
Provide a good talent environment, starting from two aspects: employee success and solving employees' worries. Through an open and inclusive mindset, we provide security and resources for talents.
In short, a benign organization can not only attract talents, but also cultivate talents, and help enterprises achieve high-quality and sustainable development.
How should the mainland lay out the future development trend?
Although China has a development opportunity in the lithium battery industry, how to maintain market stability and avoid excess capacity while promoting the sustained and rapid growth of the industry has become an important issue that needs to be carefully considered.
With the continuous advancement of technology and the change of market demand, the research and development in the field of lithium batteries is focusing on several key trends, which indicate the future development direction of lithium battery technology:
1. Enhance battery performance
Lithium batteries of the future will continue to evolve towards higher energy density, longer service life, and faster charging speeds. This needs to be achieved through the development of new materials and innovations in battery structures.
2. Improve security
Safety will continue to be at the heart of the development of lithium-ion battery technology. Researchers are developing new battery management and monitoring systems and built-in protection mechanisms to prevent problems such as overcharging, overheating, and short circuits. In addition, potential safety risks can be further reduced by improving battery materials and structural design.
3. Reduce costs
In order for lithium battery technology to be more widely used in various fields, it is necessary to reduce costs. This can be achieved by increasing production efficiency, using lower-cost raw materials, and optimizing battery recycling and reuse processes. The cost reduction will help accelerate the adoption of electric vehicles and the deployment of renewable energy systems.
4. Environmentally-friendly technology
With the global emphasis on environmental protection and sustainable development, it is becoming increasingly important to develop more environmentally friendly lithium battery technology. This includes using more sustainable or degradable materials to produce batteries, improving battery recyclability, and developing more efficient recycling technologies to reduce environmental impact.
