Historical Review of Lithium Battery Technology Development

Judging from the development trend of lithium-ion battery cathode data at that time, it is in the process of evolving from lithium-cobalt cathode data of consumer electronics products to dynamic lithium-ion batteries. From the data point of view, it is a roadmap for deglobalization. At that time, in the positive data of dynamic lithium-ion batteries, the three technical routes of lithium manganate, ternary data, and lithium iron phosphate formed the competition pattern of the Romance of the Three Kingdoms, each with its supporting company community and technology development ecosystem.

Lithium-ion battery cathode information career development

The lithium-ion battery industry continued to rise in 2011

The global lithium-ion battery industry is expected to rise in 2011. Despite the macroeconomic decline in 2011, the global lithium-ion battery market is still increasing in size. According to CCID personnel statistics, the global lithium-ion battery market in 2011 is planned to reach 15.3 billion US dollars, an increase of 29.7%, a year-on-year increase of 29.7%. The output value of lithium-ion batteries reached 4.64 billion people, an increase of 22.8% over the previous year. Yesterday, the four-year trend from the bag, after 2008, the lithium-ion battery industry has risen relatively steadily.

In 2011, the planned growth rate of my country's lithium-ion battery market was higher than the global growth rate. According to CCID employee company data, in 2011, my country's lithium-ion battery professional market planning was 39.7 billion yuan, a year-on-year increase of 43%, and the annual lithium-ion battery output value was 2.97 billion yuan, a year-on-year increase of 28.6%. According to the data of the past four years, the growth rate of my country's lithium-ion battery industry is about 10-13 percentage points higher than the world's, showing a rapid upward trend, which is consistent with the professional setting of lithium-ion battery capacity.

The proportion of data for lithium manganate and lithium iron phosphate is significantly increased

From the perspective of the growth rate of positive data storage, in 2011, my country's lithium-ion battery positive data sales increased by 33% year on year, higher than the world's 29% growth rate.

In terms of the product structure of positive data, the proportion of dynamic positive data such as lithium manganate and lithium iron phosphate has been significantly increased. In 2008, domestic lithium iron phosphate data sales accounted for only 1.8%, and in 2011 it rose to 6.01%. The proportion of lithium manganate data increased rapidly, from 6.92% in 2008 to 12.61% in 2011. From the perspective of the product share format of the entire cathode data, the rapid rise of dynamic cathode data such as lithium manganate and lithium iron phosphate has significantly reduced the market share of lithium cobalt oxide cathode data.

Skill Circle, Using Pull: Positive Data Three Kingdoms Format

Judging from the development trend of lithium-ion battery cathode data at that time, it is in the process of evolving from lithium-cobalt cathode data of consumer electronics products to dynamic lithium-ion batteries. From the data point of view, it is a roadmap for deglobalization. At that time, in the positive data of dynamic lithium-ion batteries, the three technical routes of lithium manganate, ternary data, and lithium iron phosphate formed the competition pattern of the Romance of the Three Kingdoms, each with its supporting company community and technology development ecosystem.

Three Skills Path to Prehistoric Memories

Nickel-Cobalt-Manganese ternary data adjusts data ratios to enable applications spanning high energy density consumer lithium and power lithium. The development of nickel-cobalt-manganese ternary data has gone through three stages:

The first stage was in the 1990s. The ternary chemical composition of nickel cobalt lithium manganate was obtained by solid-phase doping. The advantages are a simple synthesis process and low cost. The disadvantage is that mechanical stirring and solid-phase sintering are difficult to achieve the standard of uniform distribution of atoms. The electrochemical performance of the product is poor, and the industry has now abandoned the application.

The second stage is the beginning of the 21st century, using the hydrogen-oxygen precursor system to prepare spherical secondary particles. The advantage is that the electrochemical performance is good, and the disadvantage is that the manganese ions are easily oxidized and the process is difficult to control. On the other hand, secondary particles are easily broken during electrode rolling, resulting in low compaction density.
