Big increase in lithium iron phosphate batteries

Will a lithium phosphate battery be the future of battery-powered technology?

Past experience suggests improvements in battery-powered technology will be forthcoming for decades to come. This week, Hyundai Motor Group announced it has set an ambitious goal to develop a lithium iron phosphate (LFP) battery with an energy density of 300 Wh/kg by the end of 2025.

Can lithium iron phosphate batteries be improved?

Although there are research attempts to advance lithium iron phosphate batteries through material process innovation, such as the exploration of lithium manganese iron phosphate, the overall improvement is still limited.

How does CEO affect a lithium iron phosphate battery?

For example, the coating effect of CeO on the surface of lithium iron phosphate improves electrical contact between the cathode material and the current collector, increasing the charge transfer rate and enabling lithium iron phosphate batteries to function at lower temperatures .

What happens if you overcharge a lithium iron phosphate battery?

Overcharging is extremely detrimental to lithium iron phosphate batteries; it not only directly causes microscopic damage to the cathode material but also induces chemical decomposition of the electrolyte and the generation of harmful gasses, which can lead to thermal runaway, fire, explosion, and other catastrophic consequences in extreme cases.

What is a lithium iron phosphate battery circular economy?

Resource sharing is another important aspect of the lithium iron phosphate battery circular economy. Establishing a battery sharing platform to promote the sharing and reuse of batteries can improve the utilization rate of batteries and reduce the waste of resources.

Who is involved in the development of a lithium phosphate battery?

Hyundai Motor Group is directly involved in the battery design, while its partners handle the development process. The newly developed lithium iron phosphate batteries are expected to be installed in mid- to low-cost small electric vehicles that typically rely on nickel cobalt manganese batteries today.
