What are the differences between electric vehicle batteries?

Batteries are currently the battery products with the largest market share and the widest range of applications in chemical batteries. There are no mature alternative products in the application fields such as internal combustion engine starting and large-scale energy storage. From 2013 to 2017, the output of lead-acid batteries in my country showed a fluctuating trend. In 2014, the output of lead-acid batteries was 220.69 million kVA, an increase of 7.64% year-on-year, which was the peak output in the past five years. In the following two years, the output of lead-acid batteries in my country has declined year by year. In 2017, the output of lead-acid batteries in my country has rebounded again, reaching 207.78 million kilovolt-amperes, an increase of 1.10% year-on-year. At present, my country's batteries are mainly used in the three major fields of automobile startup, vehicle power, backup and energy storage. Among them, the automotive start-up field is the largest application field of batteries, accounting for 48% of the total application range. Nickel-metal hydride batteries The early nickel-metal hydride batteries appeared as substitutes for nickel-cadmium batteries. Due to their outstanding safety, stability, and environmental protection characteristics, they quickly occupied the markets of portable electrical appliances, power tools, emergency power supplies, etc., especially The birth of nickel-metal hydride hybrid vehicle batteries has pushed the development of nickel-metal hydride batteries to a peak. At present, nickel-metal hydride batteries are facing challenges from lithium-ion batteries and new fuel power batteries. With the gradual expansion of production, there is a trend of slowing production. In addition, under the influence of the state's policy subsidy reform for new energy vehicles, my country's nickel-metal hydride batteries have been sluggish, and the output has been declining in recent years. According to data from the Prospective Industry Research Institute, my country's nickel-hydrogen battery output showed a gradual decline from 2012 to 2017. In 2017, my country's production of nickel-hydrogen batteries was 635 million, a year-on-year decrease of 8.58%. At present, my country's nickel-metal hydride batteries are mainly used in five fields, hybrid electric vehicles (HEV), vacuum cleaners, personal care, lighting, and power tools. Among them, nickel-metal hydride batteries account for more than 90% of the application share in the HEV field. Lithium-ion batteries my country is the world’s largest production base for lithium-ion batteries, and lithium battery products have accounted for 57% of the global market share. At present, lithium-ion batteries have gradually expanded to the fields of electric bicycles and electric vehicles. The global demand for lithium-ion batteries is increasing year by year with the continuous expansion of application fields. my country is already a major producer of lithium-ion batteries second only to Japan, and the market has huge room for growth. From 2010 to 2017, the output of lithium-ion batteries in my country continued to rise. In recent years, 3C products have steadily increased the demand for lithium-ion batteries, and with the gradual expansion of the market scale of new energy vehicles and the expansion of demand for energy storage batteries, the production scale of lithium-ion batteries in my country has been expanding year by year. In 2017, my country's output of lithium-ion batteries was 11.113 billion, a year-on-year increase of 41.71%. Lithium-ion batteries in my country are widely used in many downstream fields such as mobile phones, notebook computers, electric bicycles, electric vehicles, electric tools, digital cameras, etc. They can be classified into three important categories: electric vehicles (new energy vehicles and electric bicycles), industrial storage Energy and consumer electronics products.
