CATL with CTP: 570 yuan (75 euros) per kWh; BYD with CTP: 420 yuan (55 euros) per kWh; Are you sure BYD battery costs just 55 euros. CATL being a pure battery maker should be able to sell at a much lower cost than BYD which is a dual (auto / battery maker). But the average battery cost should still be much higher. According to BloombergNEF’s annual lithium-ion battery price survey, average pack prices fell to $139 per kilowatt hour this year, a 14% drop from $161/kWh in 2022. This is the largest decline In May, commodity price reporting agency Fastmarkets said that it expected nickel manganese cobalt (NMC) Li-ion battery pack prices to fall below US$100/kWh in 2027, and lower-cost lithium iron phosphate (LFP) packs to hit the sub-US$100 threshold even sooner, by 2025. In summary, the total cost of ownership per usable kWh is about 2.8 times cheaper for a lithium-based solution than for a lead acid solution. We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology. The reason is related to the intrinsic qualities our base case, we expect innovations to contribute US$45/kWh battery cost deflation over 2020-2025, of which higher commodity prices could erode US$13/kWh, on net, leading to a US$32/kWh decline in the battery pack price (from US$138/kWh in 2020 to US$105/kWh in 2025); in a scenario of material prices reaching decade-high levels, we Fig. 10 Lithium-ion price per service regressed against a variety of possible determinants. Lithium-ion cell price per service (in kW 2 h 2 L −1) regressed against year (a), cumulative market size (b), and cumulative patent filings (c) for all (orange asterisk marks) and cylindrical (blue circles) cells. Prediction intervals (95% level) are Xb9M.
