Copper foil is
considered a "neural network" for signal reception of electronic
products and power transmission. It is an indispensable new material for
the development of new industries. 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.
