Tesla has developed a ‘very long-lasting’ battery. The nickel-based battery can last for 100 years without losing the benefits of today’s lithium iron phosphate batteries.
The battery in question should be placed in a place where a constant ambient temperature of 25 degrees can be maintained. Such conditions are somewhat difficult to imitate in practice. However, reference comparison with other technologies is possible. This shows that the battery cells described in the article last much longer than current, conventional lithium iron phosphate batteries. The benefits of energy density and charging speed are retained. Also, the service life will be longer when environmental conditions change drastically, such as higher temperatures of 40, 50 or 70 degrees.
The improved values are the product of using LiFSi lithium salts. The advantages also apply to other nickel-based processes where little or no use of cobalt is needed. The latter is important because cobalt mining results in polluted air, water and soil.
In 2016, Tesla established ‘Advanced Battery Research’ in Canada in collaboration with Jeff Dahn’s battery lab at Dalhousie University in Halifax, Canada. Tesla recently extended its contract with the group until 2026. The group has published a research paper explaining the above story.
