Tesla released details of a new electric vehicle battery that might last 100 years before it needs replacing. Battery Industry believes this comes about as a result of long-term collaboration with Dalhousie University in Canada. Tesla’s battery design reveals fresh insights into the direction the company is traveling, following astronomical increases in lithium prices.
Fresh Insights That Tesla’s New Battery Design Reveals
Tesla’s Advanced Battery Research Division first partnered with Dalhousie University in Nova Scotia, Canada in 2016. Their combined efforts now have delivered a nickel-based product Battery Industry believes ‘offers far greater longevity compared to other EV batteries’.
Tesla is currently relying on batteries with lithium iron phosphate cathodes teamed with graphitic carbon anodes. And this combination provides high energy density, and longer ranges between charges. But the new design is nickel based, according to the Battery Industry post.
Researchers from Tesla and Dalhousie University claim to be ‘theoretically able’ to overcome the design’s current limitations, they say. While offering a ‘vastly improved cycle’ after overcoming energy density and durability limitations. We append a link to the associated research paper below.
How Would the New Nickel-Based Design Work?
Moreover, the abstract to their report reads tantalizingly as follows in simplified form:
1… Demand for increasing energy with lower costs first focused interest in lithium ion batteries.
2… However, other options on the table have placed a higher priority on cycle and calendar life.
3… The latter designs suit vehicle-to-grid storage, stationary energy storage and battery leasing.
4… Their pouch cells have only sufficient graphite for operation to 3.80 V (rather than ≥ 4.2 V).
5… Such lower voltage cells therefore suit applications that require massive cycle and calendar-life.
Tesla’s new battery design reveals fresh insights into a future where low-voltage devices may have batteries that seem to go on forever.
