BYD Remains Loyal To LFP Battery For The Safety Of Electric Cars

JAKARTA Electric car manufacturer from China, BYD, reiterated its commitment to the use of lithium-iron phosphate (LFP) batteries as the main technology for all electric vehicle models. This step was taken because LFP batteries are considered to have a higher level of safety than other types of batteries.

General Manager of Brand & Public Relations BYD, Li Yunfei, said that security is the company's top priority. "Security is fundamental. Security is the greatest luxury. Security is the basic product goal," he said as quoted by Carnewschina, Saturday, November 8.

According to Li, one of the reasons BYD continues to use LFP batteries is because its thermal stability is higher and its life is longer than other types of lithium-ion batteries. He added that many reports of electric vehicle fires actually came from the use of non-LFP batteries, but the public generally does not understand the difference in types of batteries.

"As a key actor in this sector, we hope that all parties will contribute positively and prioritize security as a basic standard," said Li.

Data from BYD shows, from January to September 2025, the total installation of LFP batteries in China reached 493.9 GWh, an increase of 42.5 percent compared to the same period the previous year. Of that figure, LFP batteries control more than 80 percent of the market share of electric vehicle batteries in the country.

Technically, the LFP battery has better charging cycle resistance, capable of maintaining its capacity after more than 3,500 refills. While the lithium ternary battery on average only lasts up to 2,000 cycles.

In terms of security, LFP batteries can withstand thermal runaway temperatures of more than 500 degrees Celsius, while ternary batteries are below 300 degrees Celsius. BYD also highlighted the track record of using LFP batteries in the public transportation sector for more than 15 years, particularly on electric buses in various major cities in China.

This experience is clear evidence that LFP batteries are proven to be safe and reliable for high-risk vehicles. In the midst of the increasing interest of the automotive industry in solid state batteries as a future technology', BYD actually chooses to continue to strengthen the development of LFP as a medium-term solution. The reason is that this technology is considered more mature, stable, and supported by established charging infrastructure.
