Lithium-ion, Lithium Polymer and Lithium Iron Phosphate
Lithium offers the very best capability (ampere-hours or “Ah”) per unit weight of all metals, making it a great materials for a lithium anode. Lithium battery pack methods supply distinct advantages over different battery techniques, especially with respect to long life, reliability and capability.
A lithium energy source offers a big benefit if:
– A excessive voltage is needed (i.e. 3.Zero to 3.9 volts per cell)
– A recharging circuit just isn’t available or too expensive
– The power source must be as light weight as potential
– Long shelf life is required
– A large temperature vary is required
– Reliability is essential
– Extremely high energy density is required
– Environmental concerns corresponding to temperature, vibration or shock are particularly severe
– Your software demands a steady source of power for extensive intervals of time
Li-Ion and Li-Poly battery packs ought to at all times be used with a protection circuit to forestall the cell from over charging or over dis-charging. Choosing the proper circuit and making use of it appropriately is vital to the longevity your batteries and your individual safety.
* Important Note! We suggest that it’s best to by no means use lithium ion/polymer batteries with out safety cells. Without the safety, a slight mistake in their use may destroy the battery and they have a a lot greater danger of exploding or catching on fire.
Lithium batteries are disposable (major) batteries which have lithium steel or lithium compounds as an anode. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V to about 3.7 V, over twice the voltage of an abnormal zinc-carbon battery or alkaline cell battery.

Lithium-Ion Batteries
Lithium-ion batteries are a sort of rechargeable battery during which lithium ions move from the unfavourable electrode (anode) to the optimistic electrode (cathode) during discharge, and from the cathode to the anode throughout cost. Lithium-ion batteries are widespread in portable shopper electronics because of their high vitality-to-weight ratios, lack of reminiscence impact, and sluggish self-discharge when not in use.
The three major functional parts of a lithium-ion battery are the anode, cathode, and electrolyte, for which a wide range of supplies could also be used.
Commercially, the most popular material for the anode is graphite. The cathode is generally one in every of three materials: a layered oxide (corresponding to lithium cobalt oxide), one primarily based on a polyanion (corresponding to lithium iron phosphate), or a spinel (reminiscent of lithium manganese oxide), though materials similar to TiS2 (titanium disulfide) initially had been additionally used.
Depending on the selection of material for the anode, cathode, and electrolyte, the voltage, capacity, life, and safety of a lithium-ion battery can change dramatically.

Lithium Polymer (LiPo)
Lithium-ion polymer batteries, polymer lithium ion, or lithium polymer batteries are rechargeable (secondary cell) batteries, usually composed of several similar secondary cells in parallel addition to extend the discharge present functionality.

Lithium Iron Phosphate (LiFePO4)
Phosphate based mostly know-how possesses superior thermal and chemical stability which supplies better security traits than these of Lithium-ion know-how made with other cathode materials. Lithium phosphate cells are incombustible in the event of mishandling throughout cost or discharge, they’re more stable under overcharge or short circuit situations and they will withstand high temperatures with out decomposing. When abuse does happen, the phosphate based mostly cathode material will not burn and is not liable to thermal runaway. Phosphate chemistry additionally affords a longer cycle life.
