BYD has officially announced the launch of the Blade Battery, a development set to mitigate concerns about battery safety in electric (EV). At an online launch event themed “The Blade Battery – Unsheathed to Safeguard the World”, Wang Chuanfu, BYD Chairman and President, said that the Blade Battery reflects the firms’ determination to resolve issues in battery safety while also redefining safety standards for the entire industry.

The firm also highlighted a video of the Blade Battery successfully passing a nail penetration test, which is seen as the most rigorous way to test the thermal runaway of batteries due to its sheer difficulty. “In terms of battery safety and energy density, BYD‘s Blade Battery has obvious advantages,” said Professor Ouyang Minggao, Member of the Chinese Academy of Sciences and Professor at Tsinghua University.

The Blade Battery has been developed by BYD over the past several years. The singular cells are arranged together in an array and then inserted into a battery pack. Due to its optimised battery pack structure, the space utilisation of the battery pack is increased by over 50 percent compared to conventional lithium iron phosphate block batteries.

The Blade Battery also passed other extreme test conditions, such as being crushed, bent, being heated in a furnace to 300°C and overcharged by 260 percent. None of these resulted in a fire or explosion.

He Long, Vice President of BYD and Chairman of FinDreams Battery, covered four distinct advantages of the Blade Battery including a high starting temperature for exothermic reactions, slow heat release and low heat generation, as well as its ability to not release oxygen during breakdowns or easily catch fire.

“Today, many vehicle brands are in discussion with us about partnerships based on the technology of the Blade Battery,” said He Long. He added that BYD will gladly share and work with global partners to achieve mutually beneficial outcomes for all industry players.
