US-headquartered Microvast has launched battery technology that it claims can prevent thermal runaway in lithium-ion batteries during a press conference in Beijing, China.
The firm’s research looked at how heat released by electrolytes could be controlled to ensure safety during thermal runaway.
The technology, which can be fully charged in 15 minutes and boasts a 10,000 cycle life, took eight years of intensive research to develop.
The battery also includes a high performance separator, which has a failure point of around 300°C, the company says— an average lithium-ion battery separator shrinks at around 130°C.
The increased temperature performance reduces the chance of short-circuiting, which leads to thermal runaway.
Thirdly, the battery includes Smart Thermal Liquid (STL) technology, which is applied to the battery as a protection system.
Wu Yang, CEO of Microvast, unveiled the product saying that lithium-ion batteries contain a certain risk of random short-circuiting during production and use, which could cause accidents.
He added that even with a high-quality control standard in place (i.e., 2ppm for 18650 cylindrical batteries), in every 100,000 vehicles sold, 1,600 of them would have batteries at risk of bursting into flame.
