In 2000, Anhui Tongfeng Electronics Co.,Ltd was listed in Shanghai Stock Exchange.
In 2002, a multifuncational capacitor film line (BOPP-3) went into production. Thus, the annual output of film was up to 8000t, ranking the first in the world.
In 2002, set up a film metalizing plant in Wenzhou.
In 2003, the post doctoral workstation was set up after the approval of National Personnel Board.
In 2004, Anhui TSF Company Limited, a joint venture with SKC Inc. South Korea which is one of the top 500 in the world, was founded to produce BOPET film for capacitor.
In 2005, a heat resistant polypropylene film line (BOPP-4) went into production. This line was designed and installed by Tongfeng on its own.
In 2005, Tongfeng Electronics Co.,Ltd completed the reform of the stock equity distribution.

In 2009, Tongling Jingneng Electronics Co.,Ltd specialized in manufacturing lithium ion battery separator was founded.
In 2010, Tongfeng became the exclusive Chinese film capacitor supplier to Carrier Inc. USA. It marks that Tongfeng has achieved the world-class level in the technology, quality, costs and logistic service of the capacitors for air conditioner.
In 2011, Tongfeng Group became a private enterprise, 100% equity held by Zhejiang Tech-new Company.
In 2012, a number of modern buildings were built, including the office building, R & D Center, staff canteen and a series of standard plant buildings. Meanwhile, many new projects went on, including the expansion projects of power electronic capacitors and AC capacitors, the Sapphire wafers project and the first phase of Tianyuan & new energy project. BOPET-2 line went into production.
In 2012, Tongfeng Electronics Co.,Ltd won Tongling Mayor Quality Award.
In 2013, raised private offering of 756 million yuan in the capital market for projects of thin film used in new energy material and smart grid applications.
