How thin can
this material be? In a workshop of an enterprise in Tongling, east
China's Anhui Province, copper foils are made as thin as cicada wings. According to
an employee of the enterprise, the copper foils, which are only 6 mm
(0.23 inches) thick and used in lithium-ion batteries, can be applied in
new energy vehicle, smart phone, aviation and aerospace and other
industries. They can significantly improve batteries' energy density and
thus extend battery life, the employee added. Today, new
discoveries, technologies, products and materials are emerging at a
faster speed, and technological innovation and research are generating
infinite possibilities. This means that those whoever can do a good job
in industrial upgrading and rapidly grasp new technologies and materials
will gain an advantage in industrial reform. For cities,
only by taking advantage of the motivating role of reform, accelerating
the development of advanced manufacturing, and enhancing real economy,
can they find effective paths leading to a new development paradigm. Tongling,
which has been hailed as the "capital of copper" in China since ancient
times, enjoys rich resources, and its industries have also been going
through constant upgrading. To pursue
high-quality development, new industries in the city, represented by the
copper foil sector, have built new industrial clusters based on an
upgrade of their industrial chain. Rolls of
copper foils being produced, as well as boxes of products to be shipped
to downstream enterprises indicate the vitality of the copper foil
sector and development potential of Tongling. Accurate
positioning leads to faster development. In Tongling's Yi'an Economic
Development Zone, there is a metalware industrial park where enterprises
from Jiaxing, east China's Zhejiang Province have settled and
established industrial clusters that integrate the industrial and supply
chains. The
trans-provincial cooperation project effectively allocates geographical,
technological and land resources, forming a tiered industrial structure
in the Yangtze River delta and thus promoting the flow of production
factors and optimizing economic structure. Industrial
development is about both quantity and quality, and the two are
primarily driven by innovation. Some of Tongling's products and
technologies are very competitive, because the manufacturers have to
some extent replaced imported high-end integrated circuit materials with
domestically produced ones. A part of them are the first of their kinds
in China, and some even broke the foreign technological monopoly. To enhance
future-oriented basic research and supply of technologies at the source,
and carry out R&D for generic technology will help break
technological bottlenecks. Practices have proved that as long as
enterprises, universities and institutions work together, technological
breakthroughs can be made, and market entities will also gain an edge in
competition with technological innovation.
