PCC Phase Change Material Suppresses Thermal Runaway Spreading In Battery Pack

- Dec 23, 2016-

The composite phase change material PCC is a feasible choice for PCC with graphite and wax composition, when the lithium ion battery discharge or thermal runaway heat production, PCC wax will melt, thus the heat absorption, avoid temperature rise further.          


With the rapid development of electronic technology, lithium ion battery has become an indispensable part of our lives, and the popularity of electric vehicles is to make lithium-ion battery with our travel safety are closely linked, in May 2016 the world total sales of 2 million 500 thousand plug-in hybrid cars, and Nissan in June total sales of 250 thousand pure electric vehicles, electric vehicles have been more and more integrated into our daily life.          


After years of technical development, the safety of lithium-ion batteries has been greatly improved, but thermal runaway is still plagued by serious safety problems of lithium-ion batteries. Especially in the battery pack, in case of thermal runaway, high temperature will cause thermal runaway spread in the battery pack, the consequences be unbearable to contemplate. Tesla Model S, for example, its lithium-ion battery pack consists of more than 7 thousand batteries, once the heat runaway in the battery pack spread, will cause disastrous consequences for the 18650.          


The lithium ion battery thermal runaway feel most probably the number of Boeing, launched in the Boeing 787 Dreamliner, widely used in lithium ion batteries as storage power, used to drive the plane has not been started or mechanical and electronic equipment to stop working in the aircraft engine, the lithium ion battery safety accidents but continuous, let the plane carrying the dream of the future aircraft cast a shadow.          


In January 2013, the event of a fire in the United States Boston Japan Airlines flight 787 lithium ion batteries, according to a survey conducted by the U.S. National Transportation Safety Board, it is hot out of control 75Ah square battery a battery in Japan by Yuasa production after high temperature caused the adjacent battery thermal runaway lead after this incident, the Boeing company should be increased to prevent thermal runaway diffusion in the battery group on all measures.
