GEM-7-L3

Product Features

Nickel content of 70% or above, appearing as a black solid powder. Offers advantages such as low cost and high energy density, meeting the demand for extended driving range.

Product Applications

Primarily used in power batteries for mid-to-high-end new energy vehicles. While achieving relatively high energy density, it offers better thermal stability and safety compared to the 8-series. It is also commonly used in high-rate batteries for plug-in hybrid electric vehicles (PHEVs) and some energy storage systems.
