Method for Preparing High-Energy Electrodes with Controlled Microstructures for Energy-Storage Devices
TS-061848 — The current manufacturing methods for Lithium-Ion Batteries are limited to around 200 Wh/kg. Power density is a factor
of the battery construction and is highly dependent on the electrodes.
The Need
Conventional Li-ion batteries consist of electrodes constructed of stacks of 70 µm films. The thin electrodes then require current collectors and separators for assembly, which increase mass without adding charge capacity. The need for these inactive components limits the power densi…
