Market Research and Future Development Analysis Report on China's Lithium Battery Negative Electrode Materials Industry from 2023 to 2028

2021-11-12 11:01

The negative electrode material is first made of a mixture of negative active substances, binders and additives to make a paste evenly applied on both sides of the copper foil, and then dried and rolled to form. As an indispensable and important part of lithium batteries, anode materials directly affect the capacity, first efficiency, cycle and other main performance of lithium batteries, accounting for no more than 15% of the cost of power batteries.

Anode materials are generally divided into carbon anodes and non-carbon anodes, of which carbon anodes can be divided into graphite, hard carbon, soft carbon anodes, etc., and graphite can be further divided into artificial graphite, natural graphite, mesophase carbon microspheres; Non-carbon anodes include lithium titanate, tin alloy anode, silicon alloy anode, etc.

With the advancement of technology, anode materials have gradually developed from a single artificial graphite to natural graphite, artificial graphite, and the coexistence of a variety of anode materials such as mesophase carbon microspheres, graphene, lithium titanate, etc.

Based on the comprehensive consideration of cost and performance, artificial graphite has been widely used in the power battery market due to its good cycle performance and relatively superior safety performance. Natural graphite has high cost performance, good performance such as capacity and low temperature, and is suitable for consumer electronics, power batteries and many other fields. New anode materials such as amorphous carbon, lithium titanate, and silicon-based materials are currently in the trial stage, and are expected to be gradually industrialized in the next few years.

The market demand for negative electrode materials is showing a gradual recovery trend

The market demand for negative electrode materials is showing a gradual recovery trend

During a recent investor survey, Zhongke Electric stated that due to the end of the new energy subsidy policy at the end of 2022, combined with multiple factors such as the 2023 Spring Festival sales off-season and destocking, the demand for negative electrode materials in the first quarter decreased month on month. However, with the current production and sales data of new energy vehicles improving month by month, the demand for negative electrode materials in the market is gradually recovering.

The negative electrode material industry is ushering in a new market change

Benefiting from the growing demand in the Chinese power battery market, the shipment volume and output value of negative electrode materials in China increased simultaneously in 2018, driving the growth of negative electrode material enterprises' shipment volume. However, affected by declining subsidies, intensified market competition, rising raw material prices and declining product prices, the concentration ratio of the anode material market has further improved, and the polarization of the industry has entered a new stage of development.
