Early life and education
Peng was born in Qianwei County, Sichuan, in November 1962. He entered Sichuan University in September 1978 and graduated four years later with a bachelor's degree in chemistry. He earned his master's degree in polymer chemistry from the same university in 1985.

In July 1985, he was assigned to the Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences, as an assistant research fellow. In 1990, he went to France to study at Pierre and Marie Curie University in Paris, and earned his PhD in polymer materials two years later. He subsequently spent more than a year conducting postdoctoral research at Exxon in France.

Career 
In December 1993, Peng returned to the Chengdu Institute of Organic Chemistry as a research professor. He became vice president of the institute in February 1997, and President in June 1999. He joined the Chinese Communist Party in June 1995. In April 2001, he was appointed Vice President of the Chengdu branch of the Chinese Academy of Sciences.

In December 2009, Peng became party branch secretary of Sichuan Provincial Science and Technology Department, and concurrently served as its head in January 2010. In November 2013 he was appointed Party Secretary of Neijiang City.

In June 2015, Peng was appointed Party Secretary of Mianyang, a city that serves as an important research and production base for the defence industry. He was also the chief of the party's working committee for the Mianyang Sciences and Technology City project, responsible for working with researchers to convert military technology into civilian products. In September 2017, he was promoted to Vice Governor of Sichuan and headed the provincial commission for integrated military and civilian development, and was described as a "czar" of China's military-industrial complex. He was also elected a delegate to the 19th National Congress of the Chinese Communist Party.

Investigation
On 28 April 2019, Peng was put under investigation for alleged "serious violations of discipline and laws" by the Central Commission for Discipline Inspection (CCDI), the party's internal disciplinary body, and the National Supervisory Commission, the highest anti-corruption agency of China. According to The Nikkei, citing overseas Chinese media, Peng was suspected of leaking information on military technology to foreign intelligence agencies. He was formally stripped of his government posts on 12 May 2019.

On 10 October, the CCDI announced its investigation results. It found that Peng had accepted bribes, misspent public funds on excessive travel and dining expenses, and traded power for sex and money unscrupulously. He was expelled from the Communist Party and demoted by several official ranks. According to the announcement, he was given reduced punishment because he confessed to his wrongdoings and returned his illegal gains. He was downgraded to 4th-class investigator (). His qualification for delegates to the 11th CPC Sichuan Provincial Congress and the 19th National Congress of the Chinese Communist Party were terminated.
