Introducing Lithium Batteries

The 2L76 Battery is really a 3 Volt Lithium Non-rechargeable Battery. The 2L76 Battery is really a 3 Volt Lithium battery utilised in cameras, toys, pet containment systems, and any personal electronics that use CR1/3N lithium batteries. This battery includes a long shelf life-if this retains 90% of original service life capacity after approximately 7 years in storage.

Between electric cars, mobile phones and laptops it appears as though batteries are everywhere. This may not be planning to change sooner. Global electricity use is skyrocketing and smart phones, tablets and e-readers are increasingly common. Furthermore, batteries find applications in energy storage because the renewable energy sector keeps growing. Engineers and scientist have developed many novel technologies to provide our storage needs, but none offers established itself as the ultimate technology. Flywheel, compressed air and thermal storage are strong contenders for grid-scale storage while lithium-ion, nickel-cadmium and nickel-metal-hydride batteries compete for portable electricity storage. What is all depends upon is that we have not found an optimal approach to store our electricity. This article will discuss the technology and potential of lithium batteries.

Until the 1990s nickel-cadmium (NiCad) 2l76 battery were practically the sole choice in rechargeable batteries. The main challenge with these devices was they had a higher temperature coefficient. This meant the cells' performance would plummet after they heated up. Moreover, cadmium, one of several cell's main elements, is costly and environmentally unfriendly (additionally it is found in thin film panels). Nickel-metal-hydride (NiMH) and lithium-ion emerged as competitors to NiCad inside the 90s. Ever since then a mind numbing range of technologies have appeared on the market. Amongst these lithium-ion batteries get noticed to be a promising candidate for a wide range of uses.

Lithium-ion cells have been found in many applications including electric cars, pacemakers, laptops and military microgrids. They are extremely low maintenance and energy dense. Unfortunately commercial lithium ion cells involve some serious drawbacks. They are really extremely expensive, fragile and also have short lifespans in deep-cycle applications. The way forward for many budding technologies, including electric vehicles, will depend on improvements in cell performance.


Battery power is undoubtedly an electrochemical device. This means that it converts chemical energy into electrical power. Rechargeable batteries can convert inside the opposite direction because they use reversible reactions. Every cell is made up of a positive electrode known as the cathode and a negative electrode called an anode. The electrodes are put inside an electrolyte and connected by using an external circuit that allows electron flow.

Early lithium batteries were high temperature cells with molten lithium cathodes and molten sulfur anodes. Operating around 400 degrees celcius, these thermal rechargeable batteries were first sold commercially from the 1980s. However, electrode containment proved a critical problem because of lithium's instability. Ultimately temperature issues, corrosion and improving ambient temperature batteries slowed the adoption of molten lithium-sulfur cells. Though this can be still theoretically a really powerful battery, scientists found that trading some energy density for stability was necessary. This lead to lithium-ion technology.
