Is LFP an alternative to electric vehicle batteries? This is what the Unair teacher said

MidLand, Jakarta – One of the innovations that stands out from the trend electric vehicle it’s the use drums lithium ferrophosphate (LFP) which promises to have environmentally friendly advantages over conventional batteries.

Technical advantages of LFP batteries

Agus Mukhlisin, professor of electrical engineering at the Faculty of Advanced and Multidisciplinary Technology (FTMM), Airlangga University (Unair), said that LiFePO4 (LFP) batteries, also known as lithium iron phosphate batteries, offer a number of attractive technical advantages.

“The materials used in LFP batteries, such as iron and phosphate, are more abundant and easier to recycle than other types of batteries that use rare materials. “This supports efforts to reduce dependence on limited natural resources,” he said in a written statement, Monday, Feb. 12, 2024.

Furthermore, LFP batteries are known to have high chemical stability. This reduces the risk of fire or explosion often associated with other types of lithium-ion batteries. This safety factor is very important, especially in the context of the use of batteries in electric vehicles.

He also highlighted the long life cycle of LFP batteries. Reaching up to 2 thousand cycles, the battery has a longer life than other types of lithium ion batteries. This not only extends battery life, but also reduces the amount of e-waste generated.

Challenges related to the use of LFP batteries

While they have a number of advantages, Agus pointed out that the use of LFP batteries still faces some challenges, one of which is lower specific energy.

“The lower specific energy makes it less suitable for use in electric motorcycles where space is limited. “However, it is still possible to use LFP batteries in electric cars and buses,” he said.

In addressing environmental issues related to batteries, Agus has highlighted the importance of battery recycling programs. This program can help reduce electronic waste and reuse raw materials from unused batteries. It also highlighted the potential for reusing recycled batteries in energy storage systems such as solar power plants (PLTS). This is an effort to maximize the benefits of existing technology.

“With the full support of various parties, it is hoped that the use of LFP batteries in electric vehicles can be an important step towards a cleaner and more sustainable future,” he said.

Previously, Bandung Institute of Technology (ITB) automotive observer Yannes Martinus Pasaribu said lithium iron phosphate (LFP) batteries could be recycled. However, recycling this type of battery does not require economic costs.

“Technically, LFP batteries that are completely damaged or have reached the end of their useful life are not economical to recycle, as this process requires very high costs in the form of labor, energy and special equipment,” Yannes said.

Yannes then revealed that the price of the raw materials used in the production of the batteries is actually low, apart from lithium which represents around 5-6% of the total weight of the battery.
