The US Inches Toward Building EV Batteries at Home
The history of battery science is filled with short circuits, surges– and, occasionally, tales of redemption. One of these is the story of the lithium-iron-phosphate battery.
LFP, as it’s known, (the “F” refers to the Latin name for iron) was discovered as an excellent battery material in the University of Texas laboratory of John Goodenough. He was (and is, at 99) a famous battery scientist, best understood for developing the cathode– the crystal structure that releases and captures lithium ions as the battery charges and gets utilized– that caused the very first business lithium-ion battery in 1991. LFP, coming a few years after that, appeared to have lots of advantages over its predecessor. The cathode was stable and lasting, and potentially well-suited to powering electric vehicles. And unlike Goodenough’s previous cathode, it did not depend on cobalt, a reasonably costly metal, but rather on ordinary iron.
When Venkat Srinivasan started working on LFP as a postdoc in the early 2000s, his consultants suggested he believe about doing something else. “They said, ‘Why are you bothering with this?'” he recalls. For all its promise, LFP did not appear to have an intense future. The federal government was striving to cultivate an LFP battery industry together with a new market for electric cars and trucks, putting cash into the cause. However electrical cars and trucks weren’t taking off as quickly as hoped, so there was barely a market for batteries to power them. On the other hand, LFP was being overtaken by newer battery recipes that integrated cobalt with nickel to load more energy.
LFP, as it’s understood, (the “F” refers to the Latin name for iron) was discovered as a good battery product in the University of Texas lab of John Goodenough. He was (and is, at 99) a legendary battery researcher, best understood for creating the cathode– the crystal structure that catches and releases lithium ions as the battery charges and gets used– that led to the very first commercial lithium-ion battery in 1991. The government was trying tough to cultivate an LFP battery industry along with a brand-new market for electrical cars, pouring cash into the cause. Tesla’s partner in this undertaking is CATL, the massive battery maker in China, where the innovation was tended to over the years and quietly flourished, enhancing to the point that LFP batteries can now appropriately power a family sedan. The administration has stated the US is putting too much stake in battery technology that could just come from overseas– especially China.
There are indications that the battery market is heeding its own caution. Last month, GM and Posco Chemicals, a Korean cathode materials company, revealed strategies for an US factory to produce cathode materials. In Europe, where the battery market is not much even more ahead, Volkswagen has actually partnered with the Belgian materials company Umicore. In September, Redwood Materials, a company maybe best understood for recycling battery materials, revealed that it was also getting into the cathode-making company with strategies to construct an US factory that will produce adequate cathodes for 5 million electrical lorries by 2030. It’s a start, Srinivasan says:”For every announcement that’s made, that’s great. Now we simply require 20 more of them. ”
How odd it is then that 20 years later on LFP is everywhere. Thank Elon Musk. Over the previous year, the Tesla CEO has revealed a significant shift to the older battery chemistry– a necessity, in big part, because batteries are now in such high need that the market is headed for a products supply cliff composed mainly of nickel and cobalt. Tesla’s partner in this undertaking is CATL, the huge battery maker in China, where the innovation was tended to over the years and quietly grew, enhancing to the point that LFP batteries can now suitably power a household sedan. Like many of the significant cathode chemistries still in usage today, the battery was established in a United States or European lab, however its future is directly in China, which today manufactures 90 percent of LFP battery cells, according to Benchmark Minerals. For the United States,”LFP is a missed chance,”Srinivasan states. Srinivasan, who is now head of Argonne National Lab’s Collaborative Center for Energy Storage Science, leads a United States federal government initiative planned to avoid comparable misses. Called Li-Bridge, the program was formed this fall after the Biden Administration set an objective of making 50 percent of brand-new cars and truck sales electric. The administration has stated the US is putting excessive stake in battery technology that could just originate from overseas– especially China. Automakers likewise fear a situation similar to the present microchip supply crisis, which is requiring them to desperately jockey to be at the front of the queue as fresh chips come off the line. “The last thing I wish to be doing is to negotiate with the Asian countries to guarantee supply,” Robert Schilp, Ford’s director of purchasing for electric cars, cautioned at a conference last month. “We need to get it here.” If not, that means United States car manufacturers may end up selling less EVs than consumers desire.
