March 30, 2020—BYD launched Blade Battery in an effort to solve some safety issues regarding battery safety in electric vehicles. 

The singular cells are arranged together in an array and then inserted into a battery pack. The space utilization of the battery pack is increased by over 50 percent compared to conventional lithium iron phosphate block batteries..

While undergoing nail penetration tests, the Blade Battery emitted neither smoke nor fire after being penetrated, and its surface temperature only reached 86 to 140°F.

According to the press release, in the past few years, EV manufacturers have fallen into a competition for ever-greater cruising range. When the range becomes the prime factor to consider, this focus is then transferred to power battery makers, leading to pursuits of "energy density" in the battery industry. It is due to this  focus on "energy density" that allegedly safety has been sidelined from power battery development.
