3M and LG Chem signed a patent deal to develop large capacity lithium-ion batteries that would power an electric vehicle for 500 kilometres.

They will focus on further expanding the use of nickel, cobalt, manganese (NCM) in lithium ion batteries. Cathode compositions of previously mentioned NCM offer a remarkable "balance of power, energy, thermal stability and low cost". Changing the composition and morphology makes it possible to customize the NCM cathode materials, so they satisfy the many individual customer requirements, may it be from the field of consumer electronics or high-power electric vehicles.

According to LG Chem, which produces lithium-ion batteries based on a manganese spinel chemistry for Chevy, Ford, Hyundai, and Renault, expects the next-generation technology will pave the way for affordable electric cars with a 320 kilometers driving range by 2017. Moreover, in the near future the company will begin to offer large capacity lithium-ion batteries, holding between 80 and 120 kWh. With that kind of 'juice', a single full-charge of the battery should secure a range of 300 or 500 kilometers. By introducing electric vehicles with such a long range, they believe things may change drastically in favor of EVs, becoming more and more appealing to wider crowds of potential buyers.
