Jakarta –
Vice presidential candidate number two Gibran Rakabuming Raka touched on nickel material for electric vehicle batteries. On the other hand, many electric vehicle technologies are now starting to use LFP (lithium ferro-phosphate) batteries.
Gibran asked the position of vice presidential candidate number one Muhaimin Iskandar regarding this matter. According to Gibran, the success team (timses) of the number one presidential candidate pair is touting LFP batteries which do not require nickel from Indonesia. In fact, Indonesia has the largest nickel reserves in the world so it can become a strength. If he continues to discuss LFP, he said, it will be the same as promoting Chinese products.
“We, Indonesia, are now the country with the largest nickel reserves in the world, this is our strength, our bargaining, don’t even discuss LFP, it’s the same as promoting Chinese products,” said Gibran.
Even so, LFP battery technology is considered safer than nickel cobalt manganese (NCM) batteries. Quoted from Forbes, LFP batteries are predicted to be the batteries for future electric vehicles. Because this type of battery is considered safer from heat.
“The nickel-cobalt chemical is also somewhat susceptible to heat release if physically damaged or has a manufacturing defect that has led to six different recalls in the last three years including the Chevrolet Bolt,” wrote Forbes.
According to him, the nickel-cobalt mixture has oxygen which is released when the battery cells experience an internal short circuit and heat up. It is known that fire is created because of the fire triangle, namely a source of ignition, fuel and oxygen. Extinguishing an NCM type battery fire is somewhat difficult because the battery produces its own oxygen. Meanwhile, LFP batteries do not contain O2 so even though they can release some gas when a short circuit occurs, they will not burn like nickel batteries. This makes it much safer and more durable.
One of the electric car manufacturers that uses LFP batteries has proven this. At BYD’s electric vehicle battery manufacturing facilities in Chongqing and at BYD’s headquarters in Shengzen, China, there are test props. Electric vehicle batteries are simulated by being pricked by a needle.
In the simulation, it was demonstrated that an LFP type battery made by BYD and an NCM type battery in another electric vehicle were pierced by a needle. First, the NCM type battery is pierced by a needle. When pricked by a needle, the temperature of the NCM battery increases drastically, even up to 600-1,000 degrees Celsius. And… tworrrr the battery exploded and burst into flames. The flames continued to burn, burning the battery.
The next demonstration was piercing an LFP battery made by BYD. In the same simulation, the battery is pierced until the needle penetrates. However, there wasn’t any problem after the battery was punctured. Even if pricked by a needle, batteries made from LFP material do not get hot. As a result, the battery is safe and will not explode.
