About Li-Ion Batteries
Li-ion batteries are rechargeable batteries that use lithium ions which move from a negative electrode to positive electrode. They are popular batteries for use in consumer electronics because they provide good energy density, no memory effect, and a slow loss of charge when not in use. These batteries come in a wide variety of shapes and sizes. In addition, compared to lead-acid batteries, Li-ion batteries are lighter and provide a higher open circuit voltage, which allows for power transfer at lower currents.
These batteries have the following characteristics:
- Enhanced safety
- Exceptional low temperature performance
- Good cycle life
- High abuse tolerance
- High capacity
- High rate capability
- High temperature performance
Li-Po batteries differ from Li-ion batteries, based on the chemical used to contain the lithium salt electrolyte in the battery. Li-Po batteries contain the lithium salt electrolyte in a solid polymer composite. Li-Po batteries provide several advantages over Li-ion batteries because they cost less to manufacture, can be packaged into a variety of shapes (which is important for use in electronics such as cell phones), light in weight, and are rugged.
LiFePO4 (Lithium Iron Phosphate Batteries)
Lithium Iron Phosphate (LiFePO4) batteries use a new type of cathode material that provides several advantages over both Li-ion and LiPo including:
- Higher specific capacity
- Superior thermal and chemical stability
- Enhanced safety
- Improved cost performance
- Enhanced charge and discharge rates
- Compact size
- Light weight
- Longer cycle life
About Solar Power
Why do we need solar power?
Today, people rely on sources of external energy for the manufacturing of goods and the delivery of services. This energy allows us to live in diverse climates, in large populations, and often in controlled environments. The level of dependence on those sources varies according to the climate, level of comfort, and general needs of a community. Energy is expensive to acquire, yet easy to waste. To date, the greatest sources of energy have been fossil fuels, of which the three most commonly used are: coal, petroleum and natural gas. Unfortunately, the combustion of fossil fuels releases pollution into the atmosphere. Fossil fuels are also non-renewable. Its availability will decline.
Conversely, comfort can also be achieved with lower energy consumption through an energy efficient approach. Well planned energy use balances human comfort with reasonable energy consumption levels by allowing for the development and implementation of effective ways to create and utilize energy.
Solar energy is both a renewable and clean source of energy, which improves our environment and protects our earth from pollution. Solar power harnesses the usable energy from the sun’s light for heating, electricity generation, and desalination of seawater. The 89 petawatts of sunlight that reaches the earth’s surface far exceeds the 15 terawatts of average power consumed by humans. Solar electric generation has the highest power density among all renewable energy sources, is pollution free, needs little or no maintenance after initial set-up, and is increasingly economically competitive.
How does solar power work?
Solar cells, also known as photovoltaic (PV) cells, are panels that use the PV effect of semiconductors to produce electricity directly from sunlight. Historically the use of solar cells has been limited due to expensive manufacturing costs and relatively low solar cell efficiency. More recently, advances in research and scale of production have both reduced costs and increased efficiency, allowing for varied and innovative applications.
Photovoltaic cells generate electrical energy from sunlight and are typically used at the small to medium scale. Presently, larger arrays of solar modules are being used for pure electricity generation feeding into the power grid. Up to 20% of solar energy available at the earth’s surface can be captured by these cells. Most cells are made of silicon which act as a semiconductor, absorbing some of the light and then converting it. Unlike pure silicon, where negatively charged particles are locked in the structure and cannot move, silicon in a solar cell, which is a combination of p type and n type, has a deliberate addition of impurities so that the electrons, are free to move and carry electricity. When light hits the solar cell, the electrons move, creating an electric current that can be drawn off and used as electricity.
How do I select a portable solar generator ?
The first item to determine when purchasing a portable solar generator is total power consumption (or power wattage) of the electrical appliances, electronics, etc. that you wish to power. This will determine the selection of the appropriate system.
The second item to consider are the dimensions of the system. Portable solar generators range from sizes of a few inches to over 20 feet. Small solar generators are limited in the amount of power provided. For example, small low power solar generators can be used to power laptops, mobile phones, lamps, portable radios, portable TVs, fans, and other small appliances. Most small to medium solar generators are able to generate AC voltages found in your home (110/120 VAC) and DC voltages found in your car (12 VDC).
Where can portable solar generators be used?
Portable solar generators can be used for a variety of locations including in remote areas, while traveling, camping, boating, in an RV, or at the beach. Also, these portable solar generators can be used during and after natural disasters such as hurricanes, tsunamis, earthquakes, tornadoes, thunderstorms, and snow/ice storms. In areas where it is not practical to construct power distribution lines or to use gasoline powered generators, portable solar generators can provide a robust and economic solution.
Research and Development
The solar industry is seeing phenomenal growth because of new product innovations. These new products are a result of years of research and development in the solar field. Bioenno Power conducts on-going, in-house research and development work in the areas of : (1) New-generation of low-cost thin film solar cells using amorphous/nano-crystalline silicon and copper indium gallium di-selenide (CIGS) alloys; (2) High-efficiency, compact solar generator systems; and (3) high-power, high-energy Li-ion Battery technologies.
Next-generation Thin Film Solar Cells and Modules
Thin film solar cells are manufactured from amorphous silicon or copper indium gallium diselenide (CIGS). Thin film solar cells cost less compared to traditional mono and polycrystalline PV panels. However, at the present time, their efficiency is less compared to traditional PV panels. Future goals for thin film solar cells is to improve efficiency to meet or exceed the efficiency of traditional PV panels. Bioenno Power has also conducted extensive leading research on new-generation thin-film solar technology based on low-cost nanomaterial processing that would result in the production of high-efficiency, cost-effective thin film solar cells and modules. The core technology for advanced thin-film solar cells and solar modules is the development of high-performance photovoltaic materials that have high energy conversion efficiency.
High-power, High-energy Li-ion Battery
Bioenno Power has also conducted extensive leading research on new-generation Li-ion battery technologies based on advanced nanostructured electrode materials which would lead to the production of high-energy-density, long-service-life battery cells and the resultant battery modules/packs. The related research also includes Li-ion battery–based energy storage system for solar power and other applications.

Supercapacitors, also referred to as ultracapacitors, are energy storage devices with power and energy densities between those of a traditional capacitor and battery. But batteries store charges chemically, whereas supercapacitors store them electrostatically. Supercapacitors use electrolytes and configure various-sized cells into modules to meet the power, energy, and voltage requirements for a wide range of applications. Supercapacitors store energy using either ion adsorption (e.g. found in electrochemical double layer capacitors) or using fast surface redox reactions (e.g. found in pseudo-capacitors). These supercapacitors can potentially provide on the order of one hundred times or greater the capacity compared to standard electrolytic capacitors.
Supercapacitors offer high energy and power densities, have excellent cycle life, and can also withstand harsh temperatures. This class of energy devices has become increasingly attractive in various applications including: (1) electronic devices for consumers, and (2) weapons, tactical vehicles, and EM armor for the military.
Presently we are developing a novel class of high-energy-density, high-power-density supercapacitors using nanostructured carbon and graphene materials. These materials provide high energy density, high power density, and extremely long service life. We are also conducting work on the development of hybrid energy storage systems that combine Li-ion batteries and supercapacitors.
