The price of lithium-ion battery cells declined by 97% in the last three decades. A battery with a capacity of one kilowatt-hour that cost $7500 in 1991 was just $181 in 2018.
The cost of raw materials, particularly lithium carbonate, plays a significant role in the pricing of lithium-ion batteries. The recent decrease in lithium prices has been a major factor in lowering battery costs. As lithium is a key component in these batteries, fluctuations in its price directly impact the overall cost of battery production.
In 2023, lithium-ion battery pack prices reached a record low of $139 per kWh, marking a significant decline from previous years. This price reduction represents a 14% drop from the previous year's average of over $160 per kWh.
The price of lithium-ion batteries has been on a downward trend, reaching a record low of $139 per kWh in 2023 and continuing to decrease into 2024. The reduction in lithium prices, increased production capacity, and technological advancements have all contributed to this trend.
Effect on Battery Prices: The decrease in lithium prices is expected to further lower the prices of lithium-ion batteries, continuing the trend observed in 2023. In June 2024, the average prices for EV battery cells saw a decrease: Square Ternary Cells: Priced at CNY 0.49 per Wh, down 2.2% from May.
In 2023, for instance, the price of a battery pack accounted for approximately 30% of an EV's total cost, a notable decrease from the 49% recorded in 2016. Following CATL's price cuts, a 60-Kilowatt Battery Pack will now cost manufacturers less than $4,000.
Direct cathode recycling provides the greatest potential for carbon reduction. LFP might be the only lithium-ion battery to achieve the $80/kWh price target. Cost reductions from learning effects can hardly offset rising carbon prices. Recycling is needed for climate change mitigation and battery economics.

A solar cell fabrication process uses several high-temperature steps including a phosphorus diffusion process and a metal contact firing. The silicon wafer is p-type doped to 1 · 10 15 cm −3. The required surface doping and depth for the diffused part of the pn junction are 1 · 10 19 cm −3 and 200 nm, respectively.
Hence, the gettering process further purifies the silicon wafer. This gives room for using lower quality (and lower cost) silicon material to fabricate the wafers, knowing that they will be further purified during the solar cell fabrication.
Wafer preparation Once the monocrystalline or multicrystalline ingots are fabricated, they must be shaped and sawed into wafers for subsequent solar cell fabrication. This process implies a material loss. First, the head and tail of the ingot are discarded, and the ingot is given a square shape by cutting off the edges.
