QuantumScape introduces a new cell format for solid-state EV batteries
QuantumScape, a US battery company, has introduced a new cell format, FlexFrame, for solid-state EV batteries. FlexFrame combines pouch and prismatic cells. The FlexFrame architecture has a frame that wraps around the cell stack and a flexible polymer laminate outer layer like pouch cells. The cell is anode-free and the cell stack is contracted, with… Read more »
Layered oxide cathode could make sodium-ion batteries an attractive option for EVs
Researchers at the US Department of Energy (DOE)’s Argonne National Laboratory have invented and patented a new battery cathode material that replaces lithium ions with sodium and could be significantly cheaper. The research team has developed a layered oxide cathode for sodium-ion batteries. A layered sodium nickel-manganese-iron (NMF) oxide cathode efficiently inserts and extracts sodium,… Read more »
H&T Recharge to supply EV battery cylindrical cans to Panasonic Energy
There’s more to a lithium-ion battery cell than a handful of lithium in a little metal can. Actually, the enclosure is called a can, but it’s a highly engineered piece of hardware, designed to reduce the incidence of issues such as cell rupture and ignition. Battery supplier Panasonic Energy has signed a long-term agreement with… Read more »
Microchip’s new integrated motor drivers include controllers, gate drivers and communications in a single device
Microchip Technology has launched a new family of dsPIC digital signal controller-based integrated motor drivers. These devices incorporate a dsPIC33 digital signal controller (DSC), a three-phase MOSFET gate driver and optional LIN or CAN FD transceiver into one package. This integration is designed to reduce the component count of a motor control system design, and… Read more »
LFP batteries responsible for 36% of global EV graphite demand
According to Adamas Intelligence, 493,472 tons of graphite were deployed globally in the batteries of all newly marketed passenger EVs and hybrids from January to October 2023, up 45% or 153,034 tons from the same period in 2022. Over the same period, passenger EV unit sales rose 33% and sales-weighted average battery capacity in kWh… Read more »
