Solar power plants need to store the energy they produce, and this is one of the challenges the alternative energy sector faces nowadays. A new type of LiFePO4 battery developed by UK researchers fits perfectly for this task.
The novelty has been the replacement of lead acid batteries regularly used in such cases with the LiFePO4 (Lithium Iron Phosphate) batteries. More precisely, researchers have attached the battery to a photovoltaic system from a building and sat back to see what happens.
They observed an increase in the energy storing efficiency up to 95% compared to the 80% obtainable today from lead-acid batteries. Not to count the fact that lithium doesn’t weigh as much and its electrodes are definitely more durable (up to 1,600 charge/discharge cycles before recycling it).
The finding is part of a joint research project between the University of Southampton and a company named REAP Systems, and has been conducted by MSc Sustainable Energy Technologies student, Yue Wu and his supervisors Dr. Carlos Ponce de Leon, Professor Tom Markvart and Dr. John Low. As in any project, the battery needs further testing, but what they found so far looks pretty promising.
The consequences are long-term, especially since the battery is like the heart of a photovoltaic system: a good battery means more electricity stored for longer and less cost to purchase and maintain the system.

The Lithium Iron Phosphate (LiFePO4) batteries are based on Lithium Ion, but they offer many advantages over LiCO2 (Lithium Cobalt), frequently used in laptops, mp3 players and cell phones. They also offer a greater range, power and safety, in an electric vehicle – they will not explode or catch fire if overcharged.
DuPont, a science-based products and services company has created a new polymer-based separator for lithium-ion batteries that will improve their life and power and make them perfectly suited for electric and hybrid vehicles.
Standardization is a necessity in anything from computers, communication protocols and certain systems in the automotive industry that have to be the same with all the others, for the benefit of all car manufacturers and customers.
A Malaysian company called ETI Tech Corporation Bhd has developed the world’s first lithium-polymer battery system for solar-powered homes. â€Ã…“The lithium ion battery is 100 per cent environment-friendly, unlike the more commonly used lead acid battery,†said ETI Tech Corporation Bhd managing director K. K. Lee.
Plug-In Supply, Inc has just unveiled the “PbA10″ Conversion System last week at the Plug-in 2008 conference in San Jose. Their system is based on the CalCars’Open Source design, and it turns a standard 2004-2008 Toyota Prius into a Plug-in Hybrid Electric Vehicle (PHEV) with an all-electric range of 10-15 miles and improved average mileage of up to 100 miles per gallon (plus 1 cent/mile of electricity).
