NCA 8-series

High-Ni materials must be annealed in O2, whereas mid-Ni materials can be annealed in air. High-Ni materials require LiOH as the lithium source, while mid-Ni materials can use Li2CO3; LiOH may lead to equipment corrosion. High-Ni materials are more sensitive to humidity compared to mid-Ni materials, resulting in higher lithium residuals.

Process difficulty

Advantage

Good performance balance and relatively low cost

Moderate energy density, good cycle life, and safety

High energy density, high stability

High energy density and therefore lower cost per kWh

Good energy density, good rate capability, better stability

Applications

Heavy duty EV Long range EV

EV, Powertools, twowheelers.

*5-series means there are ~50% Ni in the composition Source: MTI, MSE, Fangzheng Report, SMM
