During recent years, the popularity of electric vehicles and hybrid electric vehicles has markedly increased worldwide. However, the main disadvantage of electric vehicles is their limited driving range, due to low battery capacity. Increasing driving range requires more batteries contributing to price, weight and volume. A practical solution would be high voltage and high energy density cathode materials.
However standard electrolyte solutions based on alkyl carbonates are oxidized at high voltage above 4.5V.
In order to use high voltage cathode materials, the electrolyte solution must resist oxidation above 4.5V. Partially fluorinated solvents demonstrate an enhanced oxidation resistance above 4.5V and are favorable to high voltage cathodes.
We propose a novel an electrolyte solution compatible with high voltage batteries, having superior performances in terms of enhanced stability, reduced manganese dissolution from the cathode and reduced capacity fading upon cycling.
The Commercial Benefit
The invented electrolyte solutions enable the development and manufacturing of high voltage and high capacity cathode material namely Lithium Manganese Rich (LMR) cathode materials.
The global electric vehicle market was valued at $118.864 million in 2017, and is expected to reach $567,300 million by 2025, growing at a CAGR of 22.3% from 2018 to 2025. Primarily designed to replace conventional ways of travel that cause environmental pollution, electric vehicles have gained popularity owing to numerous technological advancements. The electric vehicle outperforms the conventional vehicle providing higher fuel economy, low carbon emission and maintenance, convenience of charging at home, smoother drive, and reduced sound from engine.
