Appendix A – SimpliPHI Battery Safety &
Green Attributes, Certifications
This Appendix section covers the SimpliPHI Battery safety attributes and certifications, such as the lack of
thermal runaway with fire propagation, off-gassing, UN DOT certification and UL compliance and certification.
It also covers the SimpliPHI Battery’s green attributes – from products to materials to disposal, as well as
relevant environmental and ecological considerations.
A.1 – Safety Attributes and Certifications
A.1.1 – Intrinsically Safe Operation and Installation
The SimpliPHI Lithium Ferrous Phosphate (LFP) battery cell component is made with an intrinsically safe
cathode material (iron phosphate). This creates a strong molecular bond, which withstands extreme conditions,
prolongs cycle life, and maintains integrity with little or no maintenance over extended periods of time. There is
virtually no danger of Thermal Runaway with fire propagation, as there may be with Lead Acid, NiCd, and
Lithium Cobalt type batteries (NCA, NMC, LCO). No venting or cooling is required. No precautions or special
structural considerations are necessary when installing SimpliPHI Batteries.
A.1.2 – No Safety Hazards due to Off-Gassing, Exposure to Acids, Thermal Runaway
SimpliPHI Batteries do not vent dangerous gasses during normal operation, such as hydrogen and oxygen,
because chemicals contained in Lithium Ferro Phosphate cells’ electrolyte do not electrolyze to any appreciable
extent within the SimpliPHI Battery’s operating voltage range. In contrast, lead acid batteries which contain
water and sulfuric acid experience significant electrolysis into H2 and O2 during normal operation. There are
no dangers of exposure to sulfuric acid because SimpliPHI Batteries do not have caustic electrolytes. Thermal
runaway with fire propagation is not an issue with SimpliPHI products due to the basic nature of Lithium Ferro
Phosphate cell chemistry utilized in all our power storage products.
A.1.3 – SimpliPHI Battery Control and Protective Circuitry
SimpliPHI batteries utilize balancing, voltage regulation, thermal and current controls, as well as other
protective measures, in its SimpliPHI Battery Management System (BMS). This protective circuitry is
embedded in the architecture of each SimpliPHI Battery.
A.1.4 – UN DOT Certified Cells
The Lithium Ferrous Phosphate (LFP) cells are independently certified to withstand the UN DOT 38.3 testing
guidelines with no special circuitry added. These tests include short circuit, over-voltage, overcharging,
extreme temperature, high altitudes, shock and extreme vibration testing.
A.1.5 – UL Compliance
The Lithium Ferrous Phosphate cells within the SimpliPHI Batteries fully comply with the safety testing
parameters of UL 1642. Batteries have been tested to UL 9540A and are certified to UL 1973.
A.1.6 – RoHS Compliant
SimpliPHI 4.9 Batteries are RoHS compliant. Any RoHS compliant component is tested for the presence of Lead
(Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and
Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than
0.01% of the substance by weight at raw homogeneous materials levels. For Lead, PBB, and PBDE, there must
be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS
