Finally, for the minerals and metals resource use category, the lithium iron phosphate battery (LFP) is the best performer, 94% less than lead-acid. So, in general, the LIB are determined to be superior to the lead-acid batteries in terms of the chosen cradle-to-grave environmental impact categories.
Lithium iron phosphate battery refers to a lithium-ion battery using lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt, lithium manganese, lithium nickel, ternary material, lithium iron phosphate, and so on.
The names of LIB refer to the chemicals that make up their active materials, such as nickel cobalt aluminum (NCA), lithium iron phosphate (LFP), and nickel manganese cobalt (NMC). However, extraction, processing, and disposal of battery materials are resource-intensive (Tivander, 2016). These impacts should be quantified and analysed.
Lithium iron phosphate LFP is a common and inexpensive polyanionic compound extensively used as a battery cathode. It has a long life span, flat voltage charge-discharge curves, and is safe for the environment. Sun et al. prepared 3D interdigitated lithium-ion microbattery architectures using concentrated lithium oxide-based inks .
The cycle life of a long-life lead-acid battery is about 300 times, the highest is 500 times, and the cycle life of the lithium iron phosphate battery is more than 2000 times, and the standard charge (5-hour rate) can be used for 2000 times.
Lithium iron phosphate batteries are generally considered to be free of any heavy metals and rare metals (nickel metal hydride batteries need rare metals), non-toxic (SGS certification), pollution-free, in line with European RoHS regulations, for the absolute green battery certificate.

In Ghana, donor cooperation in solar PV projects started in the 1990s and has been increasing thereafter. Since 2009, a total of 9536 solar systems have been installed in remote off-grid communities in over 70 districts nationwide with support from JICA, the World Bank and the Spanish Government.
Solar photovoltaic generation is a proven renewable energy technology and has the potential to become cost-effective in the future, for it produces electricity from the solar radiation. In Ghana, the electricity demand is rapidly increasing at a rate of 10% annually.
Ghana׳s location in this region makes it natural that the application of solar energy should be given priority. The dependency on hydro energy and fossil based fuels for electricity generation has been far too long and the time has come to make use of the solar resource potential of the country .
Daily solar insolation levels range from 4 kWh/m 2 to 6 kWh/m 2 with an annual sunshine duration range between 1800 and 3000 h per annum which offers a high potential for solar electricity generation . This data is further confirmed in the Solar Wind Energy Resource Assessment (SWERA) report on Ghana . Fig. 4. GHI solar map of Ghana .
The objective of this study is to investigate the potential contribution of solar energy in achieving universal access to electricity in Ghana by 2030. The study further assesses the CO 2 emission reductions that could result from the deployment of solar energy projects towards achieving universal access to electricity.
Energy policy is at the heart of the issues affecting the implementation of solar energy in Ghana. Others include solar energy usage in power generation as well as heating and cooling purposes, technical feasibility, equipment supply, and manufacture, as well as financing. Fig. 6.

The depth of discharge in conjunction with the battery capacity is a fundamental parameter in the design of a battery bank for a PV system, as the energy which can be extracted from the battery is found by multiplying the battery capacity by the depth of discharge. Batteries are rated either as deep-cycle or shallow-cycle. . Over time, battery capacity degrades due to sulfation of the battery and shedding of active material. The degradation of battery capacity depends most strongly on the interrelationship between. . The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid. . Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic. . Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. [pdf]
The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them. The most important lesson here is this:
A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.
It turns out that the usable capacity of a lead acid battery depends on the applied load. Therefore, the stated capacity is actually the capacity at a certain load that would deplete the battery in 20 hours. This is concept of the C-rate. 1C is the theoretical one hour discharge rate based on the capacity.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
So many lead acid batteries are 'murdered' because they are left connected (accidentally) to a power 'drain'. No matter the size, lead acid batteries are relatively slow to charge. It may take around 8 - 12 hours to fully charge a battery from fully depleted. It's not possible to just dump a lot of current into them and charge them quickly.
Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
