A new battery: Lithium - air batteries

In addition, the industry has also been the other attempts, while still using an organic solvent, but different is a new composition to improve the energy density of batteries(lenovo battery). This is the lithium - air batteries. In this attempt, the Japanese Institute of Industrial Science and Technology and Japan Society for the Promotion has developed a new structure of lithium - air batteries.

Lithium - the concept of air batteries have long brought up. Because the positive use of oxygen in the air as the active material, so in theory the capacity of positive density is infinite, can increase the capacity. In addition, if the use of lithium metal anode, theoretical capacity than lithium-ion rechargeable battery(thinkpad t60 battery,thinkpad t61 battery) to improve a few.

However, lithium - air batteries, so far none popularity. The reason is that there is a fatal flaw, namely, reaction products of solid lithium oxide (Li2O) accumulate in the anode, so that the electrolyte had been cut off contact with the air, leading to discharge stops.
Made in Japan & Research Institute is divided into two kinds of electrolyte solution through this problem. In the negative (lithium) side of the use of organic electrolyte in the cathode (air) side of the use of water-based electrolyte. Set between the two electrolyte lithium-ion only through the solid electrolyte membrane, to divide them. This will prevent the electrolyte mixture, and to promote the battery react.

The negative use of lithium. Cathode is used in combination with the electrolyte containing organic lithium salt electrolyte. Although we can not abandon the organic solvent, but it limits the use. Water-based alkaline electrolyte cathode using water-soluble gel, and after the micro-based catalyst for the formation of oxides of carbon and low-cost combination of the positive.

In the cell, generated by the discharge reaction is not a solid Li2O, but easily dissolved in the aqueous electrolyte in the LiOH (lithium hydroxide). Therefore, the oxidation of lithium accumulation in the air after the electrode does not lead to work was stopped. In addition, water and nitrogen through the solid electrolyte and will not next door, so there is no place with a lithium metal anode reaction risk. Moreover, in charge, if the configuration-specific positive charge, but also conductive to prevent charge-induced corrosion and aging of the air electrode.

To 0.1A / g discharge rate of discharge, the discharge capacity is about 9000mAh / g. The previous lithium - air battery discharge capacity of only 700 ~ 3000mAh / g, can be said to achieve a substantial increase.The better than li-ion batteries(thinkpad t60 battery)

In addition, if the use of aqueous solution to replace the water-soluble gel can be in the air to 0.1A / g discharge rate of continuous discharge for 20 days, the discharge capacity of about 50000 mAh / g, compared with the original high-single digits. As the lithium metal battery capacity than lithium-ion battery had a high a number, so the value of a total of more than lithium-ion rechargeable batteries–thinkpad t400 battery,thinkpad t40 battery. high double-digit. High performance solution, but in ease of use even better on the gel. In the future need to consider which of these two, one for development.

This technology could also be considered with a simple to use rechargeable batteries(lenovo laptop battery) of different ways. If no battery charging, but replace the cathode through the aqueous base electrolyte, card boxes, etc. in order to recharge the lithium metal anode, cars will be no need to charge waiting time, immediately running. Through the recycling of used water-based electrolyte, the electric means to regenerate lithium, but also achieve the repeated use of lithium. It can be said is a new type of lithium-fueled fuel cell

Lenovo Offers Replacement for Malfunctioning Notebook Batteries

Lenovo Offers Replacement for Malfunctioning Notebook Batteries

IBM supply batteries is very well.Now,you can say “lenovo”,it is offering free replacements for batteries in six ThinkPad models that claim they’re damaged or can’t be recharged - but at least they aren’t catching on fire.

Previously, when you bought a Lenovo ThinkPad you got a 1 year battery warranty. If you had a 3 year system warranty, your lenovo battery only had a 1 year warranty. We all know that batteries are not good for a lifetime and will likely need replacement several times within the lifespan of the laptop itself.

Beginning May 19th, Lenovo launched an extended battery warranty program for ThinkPads. You do have to purchase the battery warranty within 90 days of system purchase, which I believe applies for a regular extended warranty as well, and the term of the battery warranty must match the system warranty.

Computer maker Lenovo is offering replacements for batteries in six of its Thinkpad notebook computer models that claim they cannot be charged or are “irreparably damaged.” The impacted models include the ThinkPad T60 battery, R61 battery, R60 battery, T61 battery , X60 battery, and X61 battery, span a range of part numbers; Lenovo has posted a lenovo battery diagnostic tool to help users determine if their battery is affected. Lenovo is offering replacement batteries for free.

Unlike several other notebook computer battery recalls over the years, this Lenovo battery replacement program isn’t about batteries overheating or posing a burn or fire dangers to users or property. Instead, the batteries report (via the Power Manager or Message Center) that they cannot be charger or have irreparable damage, or they exhibit inordinately low battery capacities.

To use the battery diagnostic tool, users must have the battery installed in the computer and have an active Internet connection.

Lenovo (IBM) Recalls ThinkPad Battery Packs

Lenovo (also applicable to IBM brand) has recalled 205,000 9-cell lithium-ion extended life laptop batteries made by Sanyo that used in ThinkPad notebook computers, of which about 100,000 of the battery packs are in the United States. The battery packs were installed in ThinkPad laptop computers that shipped worldwide between November 2005 and February 2007, where it could cause a fire hazard, overheat and spark if dropped hard on to the ground. This latest round of recall was second for Lenovo, previous recall was part of the recall exercise around September 2006 where 4.1 million lithium-ion lenovo batteries made by Sony for various brand such as Dell, Apple and Lenovo were recalled, also due to potential fire hazard.

The problem is not due to internal battery cells defect. Instead, casing design is the problem where if a user drops the laptop to the ground and sustains a hard strong external impact from a certain angle, the battery pack can be damaged.

Lenovo/IBM ThinkPad models which battery packs are affected include R Series (thinkpad R60 battery and R60e), T Series (thinkpad T60 battery and T60p battery) and Z Series (Z60m, Z61e, Z61m, and Z61p). The batteries comes with ThinkPad laptop, and may be purchased as optional or replacement batteries for these models too. The recalled 9-cell batteries have the part number FRU P/N 92P1131, which can be found on the battery label. 6-cell batteries are not affected.

Those with recalled lenovo battery packs can get a free-of-charge replacement batteries. Lenovo also suggests that those who might be using the laptop in a manner that might subject it to a strong external impact should remove the battery and only power the ThinkPad with an AC adapter.

How to avoid and resolve lenovo battery can not be discharge?

1. The reasons:

How to correctly use Lenovo laptop battery

First, activate the Lenovo batteries (used for the first time after the purchase of batteries or a long time do not use batteries)

Random allocation by the notebook battery for high-energy lithium-ion batteries, in the first before using the following method to activate the lenovo battery: the first use of lithium-ion battery, the battery may power only a few remnants of the need to let the battery discharge and then charge . Charge in the shutdown state.

Battery fully charged, you can use. The first three use battery power to end all use of another charge. Moreover, the charging time can not charge less than the first time. To ensure maximum battery is activated to ensure the effective use of battery time.

The process known as activation of the lenovo laptop battery. After three complete charge and discharge, the battery can be used normally.

Second, the battery initialization

Notebook batteries after a long period of use, and gradually find the actual battery discharge time than would reduce the discharge time of the original many, it is lithium-ion battery caused by the memory effect.

Can initialize the battery to remove the memory effect. Initialization refers to the battery fully charged after the release to make electricity, and once again filled with the process. Follow these steps to complete an initialization:
