The news from BYD this week about its Blade Battery is important because many people are nervous about electric car batteries, fearing they will short circuit in a car wash or a heavy rain, or burst into flames in the garage at anytime.

The company says, Blade Battery can withstand all sorts of punishments that cause ordinary lithium battery cells to implode or explode — things like being penetrated by a nail, crushed, bent, heated in a furnace to 300°C, or overcharged by 260%.

In nail penetration tests, the Blade Battery did not smoke or catch fire and its surface temperature never exceeded 60° C. Under the same conditions, a ternary lithium battery exceeded 500°C and burned violently, while a conventional lithium iron phosphate battery reached dangerously high temperatures of up to 400°C.

Developed by BYD over the past several years, the cells in the Blade Battery can be arranged in such a way as to increase the space utilization in a battery pack by 50% compared to conventional lithium iron phosphate batteries.

The first BYD model to use the Blade Battery will be the Han, which is scheduled to go on sale in June. It will be the star of BYD’s Dynasty lineup, boasting a cruising range of 605 kilometers and acceleration of 0 to 100 km/h in just 3.9 seconds.
