Panasonic has developed the industry's highest-capacity lithium-ion battery

Matsushita Battery Industrial use of positive use of nano-technology surface treatment of nickel acid lithium laptop battery, developed the energy density than the old products of the company higher capacity, "the industry's highest level" (Matsushita Battery Industrial) high-capacity lithium-ion rechargeable batteries. For example, the standard-sized notebook computer power, "18650" cylindrical battery, energy density than the old products increased by 15%, "the realization of the industry's highest energy density of 600Wh / L" (Matsushita Toshiba Battery Industrial). At the same time ensure the safety of the product.

In addition the battery compared to the past, "trickle charge" (to supplement the battery to discharge through the small current for auxiliary recharging) of the discharge after the excellent performance. Charging voltage and for the past with the +4.2 V, thus can be used with the previous lithium-ion rechargeable battery system, the same charge. Matsushita Battery Industrial to develop the technology will be applied to a square cell with cylindrical batteries, as mobile phones, notebook computers, digital cameras, such as power production. Scheduled for the beginning of October 2005 production.

At present, lithium-ion rechargeable battery cathode of lithium cobalt generally used, or used by Matsushita Battery Industry by nickel (Ni) / Mn / (Mn) / cobalt (Co) composed of lithium nickel manganese oxide materials, but products such as manufacturers want to through the use of new materials to achieve high-capacity lithium-ion rechargeable batteries. For example, in February 2005, Sony released a new type of lithium-ion rechargeable battery, by changing the cathode and anode materials used in their own, so that current capacity than the company's previous products increased 30%.

This time, Matsushita Battery Industrial in the cathode to the use of nickel oxide into the main melt metals such as cobalt and aluminum oxide compound. With past lithium and nickel-cobalt acid lithium manganese oxide, this material does not change even if the charging voltage may also increase the electrode capacity. The past, acidification nickel cathode material as the main body while improving battery capacity as the materials were high hopes, but low thermal stability due to the existence of security issues. At the same time in the charge-discharge cycle as it will react with the electrolyte resulting from the gas, so the preservation of life and there are some problems and so on.

Matsushita Battery Industrial use of nanotechnology in the surface of cathode material had a "nano-coating" At the same time, the composition of the electrolyte is optimized, thereby lowering high capacity to resolve the safety issues. Specific surface is plated with a few nm thick layer of stability. This positive in enhancing the thermal stability at the same time, but also control the charge-discharge cycle due to the electrolyte reacts with the gases generated. In the electrolyte, the current finding is also applicable to the composition of the new cathode. Did not disclose the details, there may be further controlled through the cathode and electrolyte, so that nickel oxide is more applicable to a lithium-ion rechargeable toshiba tecra a2 battery, toshiba tecra m5 battery. The stability of cathode allegedly met with the same over the past Lithium cobalt level. Anode materials is still the use of carbon, as in the past.

Johnson Controls to Acquire Delphi's Global Automotive Battery Business

Johnson Controls (Johnson Controls, Inc.) (NYSE: JCI), today announced that it has with the Delphi Corporation (Delphi Corporation) signed a non-binding letter of intent to acquire Delphi's about 212.5 million U.S. dollars in the global automotive battery operations (the specific amount to be adjusted). In addition, in conjunction with the acquisition, Johnson Controls is expected to be a global long-term contracts, which supply GM with original equipment batteries.

The acquisition of the business that can be generated by about 600 million U.S. dollars in consolidated revenues to cover the Delphi Corporation in more than 10 countries and regions of the battery business, including China and South Korea joint venture. Delphi's U.S. automotive battery manufacturing locations are not included in the transaction. In the transitional period in 2007, Delphi's contract manufacturing relationship will be from New Brunswick, New Jersey and Georgia, Fitzgerald of Johnson Controls factory to supply the battery.

The acquisition enables Johnson Controls International, Inc. to intervene in the rapidly growing Asian automotive battery market, especially the Chinese market. China is expected to total the car will double in the next five years, while new production will be double-digit growth. Access to the business in the field of original equipment batteries in China a leading position in the secondary market in China is also the case.

The transaction is expected to be completed in the summer of 2005, and ultimately depend on the due diligence process to the successful completion of a definitive acquisition agreement and the negotiation and implementation of the necessary legal recognition received.

Anshan University of Science and Technology "eradication" of used batteries

March 23, Anshan University of Science and Technology to promote the use of students is no longer a one-time ordinary toshiba tecra m2 battery, toshiba tecra m6 battery, used batteries to control the pollution of the environment and strive to create China's first "no-battery junk campus."

Anshan University of Science and Technology to support the creation of "no-battery junk campus," Application of Environmental Science and Technology Anshan Anshan University of Science and Technology Association, the campus provides a 10 dollar battery automatic teller machines, to provide services 24 hours a day. It is understood, Anshan University of Science and Technology students, after paying the deposit may be paid to the association of cells and membership cards, then, we can take no battery exchange the rechargeable battery fully charged, the battery can be returned to the Association to recover the full deposit. Anshan City, Environmental Science and Technology Association, will be regularly applied in the radio ATM cell processing carried out.
