Problems solved by technology

Although my country has implemented the production license system since 2005, due to some problems in the approval and implementation, it has not really promoted the production enterprises to achieve clean production, and many manufacturers that do not meet the standards have been converted to legalization, causing serious environmental problems.
The battery life of lead-acid batteries has not been developed by leaps and bounds. How to break through the efficiency of existing lead-acid batteries is a technology that researchers have been working hard to achieve, so that batteries can be used for a longer period of time.

Embodiment 1

[0022] Using lead as the base material, it is mixed with an alloy of antimony, arsenic and tin, in which antimony is 2% of lead (weight), arsenic is 0.02% of lead (weight), tin is 1.0% of lead (weight), and is produced by smelting Electrode plate, with calcium silicate as electrolyte, assembled into a lead crystal storage battery. After 680 charge and discharge tests, the lead crystal storage battery still has 78% of the rated capacity, and the discharge rate is 9C.

Embodiment 2

[0024] Using lead as the base material, it is mixed with an alloy of antimony, arsenic and tin, in which antimony is 4% of lead (weight), arsenic is 0.05% of lead (weight), tin is 0.5% of lead (weight), and is produced by smelting Electrode plate, with calcium silicate as electrolyte, assembled into a lead crystal storage battery. After 700 charge and discharge tests, the lead crystal storage battery still has 73% of the rated capacity, and the discharge rate is 10C.

Embodiment 3

[0026] Using lead as the base material, it is mixed with an alloy of antimony, arsenic and tin, in which antimony is 5% of lead (weight), arsenic is 0.1% of lead (weight), tin is 0.3% of lead (weight), and is produced by smelting Electrode plate, with calcium silicate as electrolyte, assembled into a lead crystal storage battery. After 650 charge and discharge tests, the lead crystal storage battery still has 70% of the rated capacity, and the discharge rate is 9C.

Abstract

The invention discloses an accumulator, specifically a lead accumulator. An electrode plate in the invention is implemented by taking lead as substrate, lead, stibium, arsenic, copper, sulphur alloys as plate materials with electrolyte replacing fluoro-sulphuric acid solution with silicate. Advantages of the invention lie in that the lead accumulator has long service life, great high-rate charging and discharging performance, rapid charge, great deep discharging performance, great low temperature resistance performance and environment protection features. Products of the invention can be widely applicable for various bicycle dynamos, automobiles and so on.

Description

technical field [0001] The invention relates to a storage battery, in particular to a lead crystal storage battery. technical background [0002] The battery industry is an important part of the new energy field and a new hot spot in the global economic development. In 2006, two of the top ten technology plans in the United States were battery projects, accounting for one-third of the total sales of the lead-acid battery industry. It is closely related to the development of industries such as transportation, information, etc. It is in a controlling position in transportation tools such as automobiles and forklifts and large-scale uninterruptible power supply systems, and is an indispensable product in social production and business activities and human life. The lead-acid battery industry is a new type of green energy system with the most promising development and application prospects in the 21st century, and it is also related to the realization of the national sustainable...
