Lithium-ion battery benefits
Technological improvements in rechargeable solid-state batteries are being driven by an ever-increasing demand for portable electronic devices. Lithium-ion batteries are the systems of choice, offering high energy density, flexible and lightweight design, and longer lifespan than comparable battery technologies. We present a brief historical review of the development of lithium-based rechargeable batteries, highlight ongoing research strategies, and discuss the challenges that remain regarding the synthesis, characterization, electrochemical performance and safety of these systems
Lithium Ion battery cells are known for their enormous energy density. They are able to store more energy per pound than any of the traditional battery packs. That makes them very popular for portable electronics, vehicles, etc. They don't have the memory effect that nicad does, and they perform the best at deep discharge applications compared to nicad or nimh. Environmentally they are safer to dispose than nicad as they don't taint water supplies, and from a mining point of view, there is no benefit or negative aspect either way.
Li-Ion is not a good battery chemistry for extreme temperatures. According to Nasa, the maximum capacity of lithium ion cells at -40 degrees C is 12% of its room temperature capacity. We've had customers who have had li-ion radio batteries stop working at -5 degrees farenheit.
Safety is another issue with lithium Ion. All lithium ion batteries have to be controlled with an integrated circuit to control input and output voltage. If the circuit is not present, the cell could have thermal runaway. I'm sure you've all heard of laptop batteries catching fire. That is an instance of thermal runaway. Another safety issue is water. In the presence of H2o, li-ion will oxidize extremely rapidly (hint explode).
The life cycle of li-ion is approximately 400 to 750. This is ever changing with the testing of different lithium salts but as of November 2012, when you purchase batteries for your consumer electronics, this will be the approximate range.
The charge and discharge curve of li-ion is extraordinary. It can handle heavy input and output voltage, making it ideal for use in power tools, electric vehicles, mobility devices, and the like.
The availability of lithium Ion is very good. There are several areas of the world that mine it, and pricing should be stable for the foreseeable future. Efforts from Wall Street to commoditize it would have negative effects on its price and availability.
