Better battery technology can expand electric vehicle range and speed up charging

At this week’s IDTechEx conference, the start-up showcased new battery technology that improves today’s lithium-ion battery design. These advances will increase the mileage of electric vehicles, reduce costs, extend service life, speed charging, and reduce the risk of fire.

At present, these improvements are mainly in the laboratory, many of which will not be realized until the next decade. But they are an important foundation for the dream of electric car supporters, who want to see traditional cars that completely replace greenhouse gas emissions with cleaner, quieter electric vehicles, and electric trucks, tractors, excavators, buses and even planes.

The most important improvement in the battery is the energy density, the amount of kWh that can be stored at a given mass. This increases the range, reduces battery costs and reduces vehicle weight, thereby increasing the range. Start-ups compete to achieve this by changing anodes, cathodes and other components.

Enevate, a Colorado start-up whose investors include battery giant LG Chem, expects its products to have more storage capacity and faster charging speeds. The company thinks its half-charge dying time is reduced to just five minutes, while the fully charged charge time is reduced to 15 minutes, allowing traditional gas stations to be converted into “plus power stations”.

The global graphene group also plans to improve batteries by wrapping silicon in anodes, resulting in a 30 percent reduction in battery costs and a power supply to electric vehicles with 700-mile range, which can be fully charged in five to 15 minutes.
