Battery world has agreed that next generation of high-performance batteries will run on metallic lithium anodes.
Sigma Lithium has the solution
Truly lithium metal anode means high charge/ discharge power at longer cycle life
Lithium content of more than 95% meaning high energy density for Li batteries with 3D-Li inside. High surface area for efficient reduction in current density, proportional to the increase in surface area
No volume change in the anode and
dendrite free
The use of porous scaffold with high surface area eliminates uncontrolled volume change during cycling and enables higher C rates at longer cycle life and low risk of dendrite formation
Scalable manufacturing process allows quick market uptake
3D-Li production involves dry, low-vacuum, energy saving process. 3D-Li is mechanically strong, can be safely handled during assembly and easily integrated into existing Li-ion battery production lines as drop-in solution
Platform anode material for various battery chemistries
3D-Li anode is battery chemistry agnostic and can be used in batteries of Gen 4b, Gen 4c with solid polymer electrolytes and in Gen 5 batteries
Copper-less anode design
No copper substrate is used as current collector. Instead, 3D Lithium metal anode utilises just lithiated carbon matrix as current collector. This makes batteries with 3D-Li inside smaller, lighter and cheaper
Anode protection:
Sigma Lithium can also provide a bespoke electrolyte additives optimised for operation in batteries with Li metal /3D-Li inside.
Our anodes can make you fly
Our porous metallic lithium electrodes will give you the energy density of 500Wh/kg combined with power of 5kW/kg required for flying.
Dendrite protection of Lithium anode is supported by proprietary 3D material structure and its interface layer.
You're in Good Company
Sigma Lithium is highly rated by some of the worlds leaders in energy technologies.
