Why use Valence Lithium Phosphate Batteries?
Long life, high capacity and excellent safety ensure an advanced energy storage solution for modern applications.
Unlike other lithium ion battery companies, Valence Technology offers safety in addition to lithium advantages, ensuring no memory effect, high C-rate capability, superior energy storage and maintenance-free usability.
But other lithium ion battery companies do not have Valence’s unique technology advantages:
- Cycle life 3-4 times that of lithium cobalt with deep cycling life at 100% DoD
- Reduced battery size & pack weight delivering better payloads
- Fast charging capability enabling higher cycles per day
- Excellent safety. Lithium oxide / mixed oxide products that have been subjected to a puncture or short-circuit will heat up and can suffer a thermal runaway event
- Advanced monitoring and control logic through Valence Battery Management System
- Our batteries are manufactured in standard industry module dimensions and supported by global application engineering support teams
Used in everything from automotive and marine transportation to medical and military equipment, Valence lithium iron magnesium phosphate (LiFeMgPO4) cathode material was derived from high investment in research & development and commercialized into the widely used U-Charge® XP & RT range of modules and supporting peripherals.
The processes and materials used in developing lithium iron magnesium phosphate (LiFeMgPO4) as the core of Valence U Charge® technology make for a technologically advanced, intrinsically safe cathode material for lithium powered applications in the market today.
Because this material has a high resistance to the liberation of oxygen, no significant exothermic event occurs upon heating. The redox voltage is low enough that no electrolyte decomposition occurs, thereby affording long cell life.
Valence Cathode Materials are prepared using a unique and versatile preparative method called Carbothermal Reduction (CTR), a process to develop lithium iron magnesium phosphate cathode powder in a very efficient, cost effective, stable and scalable way.
CTR makes Valence lithium iron magnesium phosphate powder longer-lasting, with more sustained conductivity, enhanced performance and ultimately a better cathode material that is more easily manufactured into cells.
CTR also enables Valence to efficiently convert Fe3+ into Fe2+ which can then be used in Valence Lithium Iron Magnesium Phosphate cathode powder. It uses carbon oxidation reactions to reduce iron oxides to a lower oxidation state. When carbon is used to reduce the iron oxide, a bond is formed between the remaining carbon and the iron. The stronger this bond, the greater the conductivity and overall performance of the cathode powder in any energy storage solution.
