It is understood that lithium batteries have always been the power batteries favored by new energy vehicle manufacturers. According to the related report, the output of electric vehicles will reach 13.14 million units in 2020, 5.5 times that in 2010. Among them, the output of plug-in hybrid vehicles will increase by 35 times to 1.4 million units, and the production of pure electric vehicles will reach 750,000 units, an increase of 75 times.
Because electric vehicles need high-power electric energy, in actual use, thousands of cells are often used in series to form a battery pack to ensure energy supply. According to estimates from relevant industry reports, a pure electric vehicle requires 40-50 kg of positive electrode material and electrolyte, which is about 10,000 times the consumption of a single cell phone battery. Therefore, the rise of the electric vehicle industry will undoubtedly bring dozens of times of demand growth to the domestic lithium battery industry.
According to statistics, in the first quarter, lithium battery manufacturers basically ended destocking, and the industry showed a preliminary improvement trend. In the first quarter of this year, lithium battery cell manufacturers have basically ended their destocking. The sales of most lithium battery equipment manufacturers have increased significantly. It is expected that a new round of capacity expansion will be completed in April. After April, these production capacities may enter the market one after another, and the industry shows a preliminary improvement trend.
The proportion of lithium polymer batteries and round batteries increased significantly. In the first quarter of 2013, the proportion of shipments of cylindrical batteries, square batteries, and polymer lithium batteries was 41%, 29%, and 30%, respectively. Compared with 2010, the proportion of polymer lithium batteries and cylindrical batteries has increased significantly, mainly because smart phones, tablet computers and other emerging electronic products mostly use polymer lithium batteries; at the same time their large energy consumption has led to mobile power Demand, and most mobile power uses cylindrical batteries. With the rapid popularization of smart phones, tablet computers and mobile power supplies, polymer lithium batteries have risen rapidly and become the mainstream of the future consumer lithium battery market.
The rectification of the lead-acid battery industry and the implementation of the new national standard for electric bicycles have accelerated the replacement of lithium batteries for electric bicycles. The rectification of the lead-acid battery industry jointly initiated by the five ministries and commissions and the implementation of the new national standard for electric bicycles will play a positive role in increasing the proportion of lithium batteries used in electric bicycles. Under the premise of fully complying with national standards, the lithium battery bicycle market will surely grow even further.
