button cell battery cr1620

Advances in diaphragm technology lay the foundation for the development of the button cell battery cr1620 industry

my country's battery industry has shifted from rapid growth to steady growth. From January to July 2011, the total industrial output value of the battery industry rose rapidly, and the growth rate gradually fell. The national battery industry has achieved a total industrial output value of 300.27 billion yuan, up 51.23% year-on-year, and the growth rate has declined month by month. Under the influence of the national rectification of heavy metal pollution, the output of lead-acid batteries has remained basically flat, with a total output of 78.7238 million kilowatt-hours, up 3.33% year-on-year. The national button cell battery cr1620 production reached 1.548 billion (natural units), up 18.96% year-on-year, and the output of lithium-ion batteries has increased rapidly. The national primary battery and primary battery pack (R20 standard) has achieved a total output of 1.8913 million units, up 6.02% year-on-year, and the output has increased steadily. The national solar cell production has achieved a total output of 6.0578 million kilowatts, up 88.9% year-on-year, and continues to maintain a high-speed increase.

Recently, the my country Membrane Industry Association announced the "12th Five-Year Development Guide for Separation Membrane Industry", which lists new energy battery separators as one of the key development priorities for the next five years, and proposes to accelerate the industrial development of high-performance new energy battery separators (including proton fuel cell batteries, lithium-ion batteries and vanadium batteries, etc.), achieve mass production, and achieve performance close to or reaching the international advanced level. The separator is a high-value-added material with the highest technical barriers among lithium battery materials, with a gross profit margin of up to 70%, accounting for 20%-30% of the cost of lithium-ion batteries, and has a direct impact on battery safety and cost. During the "12th Five-Year Plan", the localization of "membranes" became the focus of national support.

Recently, the International Energy Agency (IEA) updated the "Electric Vehicle (EV) and Hybrid Electric Vehicle (pHEV) Technology Roadmap" for 2050, which was announced by the agency in November 2009. The new plan proposes that the industry and the government work together to achieve global EV and pHEV sales of at least 5 million vehicles per year by 2020, and account for more than half of light vehicle sales by 2050.
