For electric car , power batteries have an important impact on both battery life and cost. Having a battery that is both cheap and can bring long battery life has always been the goal pursued by many battery companies and car companies. Recently, an American energy storage company called Next Energy (ONE) launched an anode-free lithium-ion battery cell with extremely high energy density. The biggest feature is that it can meet the above two major needs: cheap and very high energy density.
The company claims that the 240 Ah prism-shaped anode battery developed in-house has a unit energy density of 1007Wh/L, which is probably the largest energy density large-format battery ever. Although the company did not disclose how much unit energy density it was finally equipped on the power battery, this theoretical parameter does look very excellent.
Ultra-high energy density battery pack
High energy density is not the only advantage of this anode-free battery, because there is no need for graphite anode and anode manufacturing equipment, and its price is expected to be only half of that of a conventional battery. The company estimates that when mass production is made, the new battery may cost only US$50 per kilowatt-hour, which means that even a large-capacity battery with 100kWh will cost only US$5,000 (about RMB 35,000). For reference, the 100kWh battery pack launched by NIO was bought out at a price of up to RMB 138,000.
High energy density battery pack
Compared with traditional batteries, anode-free batteries usually have lower cycle life, which limits their prospects for use in the field of power batteries. However, the company has launched a dual-chemical battery architecture called "Gemini", which consists of lithium iron phosphate battery and anode-free battery. In daily short-distance traffic, the vehicle is powered by lithium iron phosphate batteries, while anode-free batteries will increase the overall energy density of the system and provide a stable power output when long-distance travel (up to 724 kilometers of range).
"Gemini" dual-chemical battery architecture
This company's strategy can theoretically reduce cycle life and peak power requirements by 90%, which is enough to commercialize anodized batteries in electric vehicles. It is estimated that the life expectancy of the entire battery system can reach 400,000 kilometers, which is also a significant lead in current power batteries.
power battery car chassis
Earlier this year, the company had received $265 million in financing from BMW html, and the company's battery pack is also planned to be equipped with the test car of BMW iX pure electric SUV this year, with the goal of achieving a range of 600 miles (965 kilometers).
