Current status of lithium battery cathode materials industry at home and abroad

Release date:2018-08-22  source:粉体网  Browse times:1222
       In recent years, the double harvest of China's new energy vehicle production and sales has driven the rapid development of the entire upstream and downstream industry chain, especially the demand for power batteries continues to rise. New energy vehicles put forward higher requirements for power lithium batteries. Energy density, cost, safety, thermal stability and cycle life are the five key performance indicators of power lithium batteries. As the core of the power lithium battery, the positive electrode material accounts for about 30-40% of the new energy vehicle manufacturing cost.

1. Technical status of cathode materials for power lithium batteries

At present, large-scale market applications mainly include lithium iron phosphate (LFP), lithium manganate (LMO) and ternary materials [lithium nickel cobalt manganese oxide (NCM) and lithium nickel cobalt aluminate (NCA)]. Among them, lithium iron phosphate and lithium manganate materials have not much room for technological breakthroughs in basic research, and their energy density and main technical indicators are close to the application limit. From the perspective of technological progress, ternary materials have gradually become the mainstream of power lithium cathode materials due to their high energy density, long cycle life and high reliability.

Third, lithium battery cathode material industry development analysis

Global lithium battery cathode material market size

In 2016, global lithium battery shipments reached 118GWh, of which the shipment of power lithium batteries increased from 1.08GWh in 2011 to 40.52GWh in 2016, and the market share increased from 2.32% to 34.30%.

In 2017, the global shipment of lithium-ion batteries reached 143.5Gwh, of which the shipment of automotive power lithium batteries (EV LIB) reached 58.1Gwh, and the shipment of energy storage lithium batteries (ESS LIB) reached 11.0Gwh, other traditional fields. The shipment of lithium batteries (Small LIB) reached 74.4Gwh.

Driven by the rapid development of lithium batteries and its downstream industries, lithium battery cathode materials grew rapidly. In 2016, global lithium-ion battery cathode materials sales reached 317,400 tons, an increase of 42.1%, and the compound annual growth rate for 2011-2016 was 32.17. %. From the application structure, the lithium battery cathode material market can be subdivided into a small lithium battery cathode material market and a power lithium battery cathode material market. The small lithium battery cathode material mainly includes lithium cobaltate, ternary material and lithium manganate, while the power lithium battery cathode material is mainly lithium manganate, lithium iron phosphate and ternary materials.
China's lithium battery cathode material market size

In 2014-2016, the cathode materials of lithium-ion batteries showed a rapid growth trend. In 2016, the output value of cathode materials for lithium batteries in China reached 21.76 billion yuan, a year-on-year increase of 43.3%, mainly due to the explosive growth of China's new energy vehicle market. The demand for power lithium batteries is growing rapidly.

Fourth, power lithium battery cathode material market outlook

In the past three years, China's new energy vehicle production has exploded exponentially. At present, China has become the largest producer of new energy vehicles. Due to the rapid development of China's new energy automobile industry, the demand for power batteries has also skyrocketed, resulting in the shortage of power lithium-ion battery capacity in China in 2015, and various power battery companies have rapidly expanded their production capacity. In 2015, China's domestic power battery capacity was about 20GWh, and in 2016 it exceeded 60GWh. The explosive growth of new energy vehicles has led to sustained high-speed development of the overall lithium battery industry. It is expected that the total demand for lithium batteries will reach 130GWh in 2018. In 2018, the global lithium battery cathode material is expected to exceed 300,000 tons. Among them, the ternary materials will develop rapidly, with an average annual compound growth rate of more than 30%. In the future, NCM and NCA will become the mainstream of automotive cathode materials. It is expected that the use of ternary materials will account for about 80% of automotive materials in 2018.

Most countries in the world have set planning targets for new energy vehicles. It is estimated that by 2020, the global sales of new energy vehicles will exceed 18 million, of which China has the largest target.

China's cathode materials industry has attracted much attention in the development of global power lithium batteries. On the one hand, some Chinese lithium battery cathode materials manufacturers have continuously improved their technology level with the international lithium battery manufacturers in the past few years, and have gradually approached the international cathode materials counterparts, China. The industrialization of power batteries has already been supported by domestically produced power batteries. On the other hand, China's new energy vehicles and power lithium batteries have achieved remarkable achievements. once the market demand increases, China's lithium battery cathode materials industry will be further promoted. Accelerated development.
