BRIN Develops Active Materials To Create New Generation Batteries

JAKARTA The National Research and Innovation Agency (BRIN) is focusing on developing active materials for the new generation of batteries. This battery is expected to be safer, more efficient, and environmentally friendly.

BRIN's main research, through the Energy Material Research Center, includes the development of a high nickel cathode (Ni-rich NMC) to increase battery energy capacity. In addition, they also researched the Li4Ti5O12 (LTO)-based anode known for its stability.

One of the important breakthroughs in this study is the Li3PO4-based solid electrolyte synthesis using the Spark Plasma Sintering (SPS) method. This solid electrolyte offers better thermal stability and is not flammable.

BRIN Main Expert Evvy Kartini explained that lithium-ion (Li-ion) batteries are the backbone in the global clean energy transition. This battery excels due to high energy density, fast charging efficiency, and long lifespan.

It should be noted that the Li-ion battery consists of four main components, including cathodes, anodes, electrolytes, and separators. Each of these components has a very important role. This type of battery is often used in electric vehicles (EVs) and energy storage systems (ESSs).

"The lithium-ion battery is not just a component of technology, but is a strategic element in efforts to decarbonize transportation and national energy independence," Evvy said, quoted from the official BRIN website on Monday, November 10.

To support research, BRIN has developed a battery performance and safety testing facility with its partners. This facility includes testing cells and battery packages, vibrations, mechanical shocks, and resistance to extreme temperatures.

The testing facility supports the implementation of international security regulations, such as UNR 100 and UNR 136 for electric vehicles. The UNR 136 adoption is essential to ensure the safety of electric energy storage systems (RESS) on electric vehicles.

Evvy explained that facilities supporting UNR 136 standards should not experience electrolyte, explosion, or fire leaks after intensive testing. This regulation ensures that the batteries used are safe in various operational conditions.
