High-performance Lithium Ion batteries

The technology relates to a sol-gel based, uniform carbon-coating method for producing high-performance lithium-ion batteries. This method makes use of organic phosphoric acid as carbon and phosphoric sources to produce uniformly carbon-coated lithium-ion batteries that overcome the challenges of low capacity and low energy density that ultimately result in battery failure. This method allows the manufacture of batteries that can be used in applications requiring a long-life cycle and significant safety.
