Like lithium ion batteries, they do not suffer from battery memory but are also effected by gradual capacity loss caused by oxidization. It happens over a span of years from the manufacturing date, and lithium polymers (lipos) are basically lithium ion batteries that are easier to mold into various shapes needed for certain applications.

Which is more powerful lithium ion or nickle cadium battery?
well your question is kind of awkward. a lithium battery is a cell battery, so i will outline all types of batteries and you can pick which you meant. Lithium Ion/ Lithium Polymer batteries- These are the most expensive, longest lasting, and lightest batteries. they have the highest power density and have no battery memory (that's when u recharge a battery before its empty and it wont go back to empty)- making them the best batteries for most applications. they have high amperage and voltage. BUT BEWARE lithium batteries have two flaws; you need a special charger and you CAN NOT let them completely run out of battery. if you don't follow these rules, you battery will not hold a charge and become useless.... these are rechargeable. Nickle Metal Hydride- these are great all purpose durable batteries. they have slightly lower chaarge life amperage and voltage that lithium, but they do not have the care problems that come with lithium batteries. NiMH batteries MAY be fully discharged if you wish, but do not need to be. also they can work with the normal battery chargers.... these are rechargeable Nickle Cadmium- these are probably the WORST rechargeable batteries. They MUST be fully discharged or else they lose part of their chargelife- this is called battery memory. this means either leaving whatever ur running on until it dies, or buying a special discharger. these batteries also have less power than NiMH in terms of both amperage and voltage. Regular non-rechargeable batteries- lowest amperage, variable voltage. non-rechargeable by definition >.< i wouldn't use these except for cheap, low power applications... like... flashlights. nothing you should be using often.
What is a special polymer?
It is a polymer which has special properties such as a memory shape polymer.
How do you prolong lithium-based batteries?
Simple GuidelinesAvoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.
What is a neat polymer?
A new and usefull polymer is new polymers that are developed to help society- for example shape memory polymers are used to cure cuts.When a shape memory polymer is used to stitch a wound your body tempreture makes it tighter and close around the wound.This is just one example of a new polmer which is usefull. Hope i helped.
Is there a difference between ni-cd batteries and ni-mh batteries?
Quite a few differences. Nickel-metal-hydride (ni-mh) batteries: Charge Faster; Hold a charge longer; Have far less 'memory effect'; Last longer; But are generally more expensive. Ni-mh batteries are by far the better choice.
Lithium Batteries Have No Memory Effect?
When you buy lithium polymer batteries, you can do so with the knowledge that they do not have the dreaded memory effect. This new technology is much better than the batteries that used to be used in computers, phones, and the like. These batteries would remember how full they were when you plugged them in, and they would count that as being empty, even if they were not. The lithium polymer batteries do not do this.
What rechargeable battery has not memory?
Lithium-Ion (li-ion) batteries have no memory, new laptops use these
Get Full Power From Your Batteries,Uuse AA Lithium Batteries?
Remember batteries with memories? You had to go through all the nonsense of completely discharging then recharging your batteries or your battery developed a memory. After a while you only got half the use from your battery. Batteries are too expensive for that nonsense. Get AA lithium batteries and get full power from them first time and every time. Lithium batteries are especially important for high power items like cameras and flashes.

What is a mobile phone battery made from?
cellphone batteries are made of LITHIUM ions. u all must have noticed the symbol "Li+", on the battery which denotes lithium ions. cellphone batteries are made of LITHIUM ions. u all must have noticed the symbol "Li+", on the battery which denotes lithium ions.
Laptop Battery Types?
When not plugged in, laptops require batteries to power the device. Battery types for notebooks can differ. Nickel Cadmium (NiCd) batteries are low in cost, versatile, and the first rechargeable batteries for laptops. Nickel Metal Hydride (NiMH) batteries are significantly better due to improvements in capacity, safety, and reliability. Lithium Ion (LiON) batteries are most popular due to being lightweight and improved memory effect. "Smart" or "dumb" batteries are better at managing battery energy and reporting charge state.
What are the benefits of lithium ion batteries compared to other batteries?
All rechargeable batteries develop a "memory effect", which occurs over time. This effect limits the ability of the battery to recharge close to its fullest potential charge. How quickly this problem manifests itself can directly depend on the discharge/charge cycle of the battery during its lifetime. It is always best to discharge a battery completely - or close to it - before recharging it. NiCAD and NiMH are older types of batteries where NiMH had more resistance to the "memory effect" than NiCAD. Hence, NiMH was a breakthrough in battery technology once upon a time. Now we have LiION batteries that are a major improvement over the NiMH batteries.
Why is nicad batteries different from regular batteries?
Ni-cad batteries first became popular as portable rechargeable batteries. The "regular batteries" used in cars are mostly lead-acid rechargeable batteries. The "regular batteries" used in toys, remote controls, flashlights and such, are mostly the non-rechargeable types. Ni-cad batteries use nickel and cadmium. The latter is a toxic substance, difficult to dispose of, and ni-cad batteries have a nasty tendency to lose capacity (the "memory" effect). For that and other reasons, makers of lightweight rechargeable batteries have switched to using nickel-metal-hydride or lithium batteries. (Lithium-metal = explosive, lithium-ion = very popular, lithium-polymer = extremely lightweight, lithium-iron-phosphate = next generation for hybrid and electric cars.) The Prius Hybrid uses nickel-metal-hydride battery cells. When weight or size is not as much of a concern, lead-acid batteries are used due to their lower cost. Most automobiles and many industrial uninterruptable power supplies use lead-acid batteries, which are capable of providing several hundred amperes of current for a short time. Ni-cad batteries are rechargeable, regular are not rechargeable.
What has the memory a phone or its battery?
The phone circuits contain the working memory of the phone. Most lithium ion rechargeable batteries (like those used in phones and laptops) contain a tiny printed circuit board with a Flash memory chip, temperature sensor, etc. inside its case. The microprocessor in the phone (or laptop) will periodically update statistics in this Flash memory chip to keep track of battery health. When you replace the battery this Flash memory chip goes with it.
Do you need to completely drain the battery the first time you charge your ipod touch before charging it again If you do not do this what happens?
this is what is says on apple.com FAQ;Question: Do I need to completely empty the battery before charging it, and does doing this prevent the so-called "memory effect"?Answer: You don't need to empty the battery before charging it. Lithium-based batteries, like those used in iPod, have none of the memory effects seen in nickel-based rechargeable batteries.
If I charge my phone battery tonight which has 2 bars left will the battery go flat quicker?
All batteries have different characteristics. One of the noted properties of nickel cadmium batteries is that they develop a "memory" if they are frequently charged without a full discharge before. If is this battery type that has generated the belief that rechargeable batteries will all have a memory. Cell phones almost all use lithium ion batteries. These store far more energy than other types, for a given battery volume and they do not have a memory effect. They are therefore ideal batteries for compact and lightweight devices like phones and MP3 players. However, they are by no means the perfect battery. Lithium ion batteries are hazardous if they are not charged correctly. One way that chargers avoid over charging the battery is to monitor the charge being used by a device and then only put in that same amount of charge. Sometimes, if the measurements are not exactly right, the charge can be less than the discharge and the battery charge will creep ever lower. The appearance is that the battery has developed a memory. The normal method to overcome this is to fully discharge the battery at intervals, which will then allow the charger to deliver a full charge. The precise charging method varies from one device to another so this isn't a universal fix. The second problem is that of battery life. Most rechargeable batteries will be less effective after a certain number of charges. Lithium ion batteries will simply decay over a period of time. This ageing process is accelerated when the battery is at a high temperature. The technology is improving continually but some lithium ion batteries would lose up to half of their storage capacity after less than a year. A camera that is stored in a glove compartment of a car (a very common place to leave it) could require a replacement battery in just a few months. So, to get the best out of a cell phone battery, allow it to discharge completely once every month or so and try not to leave the phone in hot places more than is necessary.
ARE nicad batteries subject to memory effect or not?
Yep. This type of battery is most famous for suffering from the memory effect, which is one of the reasons for why NiMH batteries have largely replaced them.
