Lithium Iron Phosphate Storage Systems

Lithium Iron Phosphate (LiFePO4) is one of the most interesting and promising cathode materials for lithium accumulation systems of energy.

Thanks to a close and well-established cooperation with Lithops, a company that develops and implements highly innovative and technological processes for the chemical synthesis of the active material and the production of Lithium Iron Phosphate cells and storage systems, Soimar has now a very important and qualified know how of all the stages of realization of such accumulation systems.

Chemical synthesis of the active material
Lithium Iron Phosphate (LiFePO4) has numerous advantages compared to other materials: high specific capacity, high discharge and constant voltage during almost all of the charge and discharge, high cyclability (low degradation of the material), possibility of use even in high temperatures applications, low environmental impact, low cost.
In this context, R&D constantly endeavors to implement new procedures for the chemical synthesis of the active material, the most effective and economic, and to optimize time, cost and results of the existing ones.

Anodes and cathodes formation
The electrode of a lithium battery is a porous composite tape, deposited on a current conductive support composed of active material, an electronic conductor and a polymeric binder.
The composition of the electrodes and, in particular, of the cathode tapes needs to be designed and implemented as a function of the nature and content of the various components and the realization process type in order to obtain optimal mechanical / thermal characteristics, porosity and electronic (and ionic) conductivity for applications in lithium storage systems, which can be used in many and different sectors (industrial, automotive, domestic use, etc ..)

Cells and customized systems
The anodic and cathodic materials selected and developed in the previous points are then integrated into a complete electrolyte cell (liquid and / or polymeric), specifically defined and designed for the application at which is aimed (high specific energy or, alternatively, high specific power; in lab scale for performance verification in the next operating conditions to the end-use ones or in industrial production scale).

Thanks to this in-depth process knowledge, Soimar is able to plan, manage and coordinate all the development and implementation of:
– Research laboratories
– Pilot plants
– Establishments of small, medium and large dimensions

for the synthesis of the active material up to the large-scale production of customized plants through the various steps of:

  • Feasibility analysis
  • Basic and detailed engineering
  • process equipments definition and purchasing
  • construction of all process and auxiliary plants
  • dry rooms: walls, ceilings, floors, related plant
  • commissioning and start up
  • validation
