Alternative to cobalt-based cathodes in li-ion batteries

Oak Ridge National Laboratory researchers have developed a potential replacement for cobalt-based cathodes in li-ion batteries called NFA (nickel-, iron- and aluminum) – a derivative of lithium nickelate. “Lithium nickelate has long been researched as the material of choice for making cathodes, but it suffers from intrinsic structural and electrochemical instabilities,” says ORNL’s Ilias Belharouak, “in ...

LDDI market tightening; prices rising

The market for large display driver ICs (LDDIs) has tightened, says TrendForce, as foundries shifted their 8 inch capacity to other products. This transformed a 3.3% supply surplus in 2019 to a 1.7%  surplus in 2020 and resulted in 20-30% q-o-q price increases in H2. As well as foundry price increases, assembly capacity has been insufficient ...
