Lithium-Ion Battery Cost Per Kwh

Introduction

This is a rechargeable battery in which lithium-ion produces power. The lithium-ion battery consists of negative and positive electrodes. This is a rechargeable battery in which lithium ions travel from the negative electrode to the positive electrodes via an electrolyte. The discharge goes forward and backward when charging. Many devices employ lithium-ion (Li-ion) cells, including gadgets, games, Bluetooth headphones, portable power instruments, small and big utilities, electric cars, and electrochemical energy storage devices. They can endanger health and the environment if not appropriately handled at the end of their lifecycle.

Trend

The rising market demands for Li-ion batteries may be attributed in large part to their high "power density." The quantity of energy that a system holds in a given number of spaces is referred to as its "energy density." While retaining the same quantity of electricity, lithium batteries can indeed be thinner and lighter than some other battery types. This downsizing has accelerated consumer acceptance of small transportable and wireless devices.

Lithium-Ion Battery Cost Per Kwh Trend

A rise in battery prices might push out benchmarks such as the $60 per kWh set by the US Energy department as the break-even threshold for EVs against engines of the internal combustion. As per the annual battery pricing study of Bloomberg New Energy Finance (BNEF), world average battery costs declined 6% between 2020 and 2021, however they may be on the increase in the future.

According to the research, lithium-ion battery pack costs were $132 per kWh in 2021, dropping from $140 per kWh in 2020, and $101 per kWh on a cell level. As per the analysis, increased commodity prices are already pulling prices back up, with a $135 kwh median pack price expected for 2022. According to BNEF, this might imply that the moment at which costs fall below $100 per kWh—generally regarded as a critical milestone for EV affordability—will be postponed by two years.

Car manufacturers have lofty goals of their own, such as Toyota's objective of cutting EV prices in half in ten years. So do entire countries and states. Will it fight back objectives if cells are becoming more costly in a year or two? That remains to be observed as a new component in this complicated EV-adoption trendline.

Battery Price Increase

Lithium-ion battery prices have increased to a greater extent. The reason behind the surge in the prices is the materials.

The prices of the materials of Lithium-ion Have Increased Significantly.

Although the cost of batteries has been dropping since 2010, significant price increases in key cell metals like lithium have thrown doubt on their longevity. How will EV battery prices develop in the future? The price of lithium-ion batteries may increase in the upcoming future to a greater extent.

The Surge In Price Is Not A New Thing.

It's not the first research to point to raw material shortages as a possible precursor to increasing battery pricing. Other publications have identified nickel as a possible shortfall, not all cells require it.

However, according to BNEF, supply-chain concerns have even driven up prices of raw materials for the lower-cost lithium iron phosphate (LFP) chemical, which is now favored by many big Chinese manufacturers and battery manufacturers and is being progressively embraced by Tesla. According to the research, Chinese LFP cell makers have boosted their pricing by 10% to 20% since September.

How Much Does A Lithium-Ion Battery Cell Cost?

Let us break down the price of a lithium-ion battery cell cost. According to BloombergNEF statistics, the price of each cell's cathode accounts for more than half of that amount cell price. 

V Battery Cell Component % of Cell Cost
Cathode 51%
Housing and other materials 3%
Electrolyte 4%
Separator 7%
Manufacturing and depreciation 24%
Anode 11%

From the above breakdown of lithium-ion battery price, we have discovered that the cathode is the most expensive material. It accounts for 51% of the entire price. 

Why Do Cathodes Have Higher Prices?

The cathode has a positive charge electrode. When the device drains the battery, electrons and lithium ions travel from the anode to the cathode. They remain there until the battery gets fully charged again. Cathodes are the most important component of batteries. It strongly impacts the range, performance as well as thermal safety of the batteries. Hence, this is also an EV battery. 

The cell consists of various metals. For instance, it consists of nickel and lithium. Nowadays, the common cathode compositions are:

Lithium iron phosphate (LFP)

Lithium nickel cobalt aluminum oxide (NCA)

Lithium nickel manganese cobalt (NMC)

The battery elements that comprise the cathode are in great demand, with manufacturers such as Tesla scrambling to obtain materials as EV sales surge. In reality, the goods in the cathode, together with others in other cellular components, make for around 40% of the total cell price.

Prices of Other Components of Lithium-Ion Battery

The remaining 49 percent of a cell's cost consists of components other than the cathode. The production process, which includes making the electrodes, integrating the various components, and completing the cell, accounts for 24% of the entire cost. The anode is another essential part of the batteries, accounting for 12% of the overall cost—roughly one-fourth of the cathode's portion. A Li-ion cell's anode consists of the organic or inorganic graphite, which is less costly than other battery materials.

Conclusion

However, increased raw material prices suggest that average pack costs might grow to 5/kWh in nominal terms by 2022. In the absence of external advances that might reduce this effect, the time at which costs drop below 0/kWh may be delayed by 2 years. This would have an influence on EV affordability and manufacturer profits, as well as the economy of energy storage installations.

Continued R&D investment, as well as capacity growth throughout the distribution network, will assist to advance battery technology and lower prices over the next generation. BloombergNEF anticipates that next-generation innovations like silicon and lithium-based anodes, solid-state chemistries, and novel cathode substance and cell production techniques will play a significant role in facilitating these price decreases.
