Advanced battery technology can enhance the range and charging speed of electric vehicles

At the IDTechEx conference, start-up companies demonstrated new battery technologies and improved the design of today’s lithium-ion batteries. These developments will increase the mileage of electric vehicles, reduce costs, extend the service life, speed up the charging speed, and reduce the risk of fire.

  

Currently, these improvements are mainly carried out in the laboratory, many of which will not be realized until the next ten years. But they are an important foundation for the dreams of electric vehicle supporters. They want to see those traditional cars that emit greenhouse gases with cleaner and quieter electric cars. They also want to see electric trucks, tractors, excavators, and public vehicles. Cars and even airplanes appeared.

The most important improvement in batteries is the energy density, which is the amount of kilowatt hours that can be stored under a given mass. This can expand the cruising range, reduce battery costs and reduce the weight of the vehicle, thereby expanding the cruising range. Start-ups are racing to achieve this goal by changing anodes, cathodes and other components.

Enevate is a Colorado start-up company whose investors include battery giant LG Chem, hoping that its products can have larger storage capacity and faster charging speeds. The company believes that the charging time for a half charge of its products is reduced to only 5 minutes, while the charging time for a full charge is reduced to 15 minutes, allowing traditional gas stations to be converted into “refueling stations.” Global Graphene Group also plans to improve the battery by wrapping silicon in the anode with graphene. The result will reduce the cost of the battery by 30% and power electric vehicles with a range of 700 miles. These batteries can be fully charged in 5 to 15 minutes. .
