Abstract:

Due to years of cultivation，China′s lithium battery industry chain is fully developed，battery technology has made obvious progress，the lithium market is growing rapidly，and the industry has ushered in more development opportunities.On the one hand，as an emerging industry encouraged by the state，the lithium battery industry is promoted by policies and technological progress and develops rapidly.On the other hand，lithium resources and other problems also restrict the development of lithium battery industry.The development of lithium ion battery technology and industry chain were introduced by studying relevant literature and information，the important factors affecting the development of lithium battery industry including policies，development of lithium battery technology，cost and lithium metal resources were discussed，and the development of global lithium battery market based on relevant data was forecasted.In the next three years，the global lithium ion battery market would continue to maintain rapid growth and was expected to usher in the“TWh”（“100 million kW·h”，i.e.1 000 GW·h，the same below） era.The deficiencies in performance，recycling，industry standardization and energy production were pointed out.It was suggested to increase research efforts and explore appropriate policies to promote industry standardization，and to caution against short?term overheated development and excess capacity.

Key words: lithium ion battery, policy, lithium resources, market
