Lead/acid battery myths

摘要

The lead/acid battery deserves a more positive image than has been traditional heretofore — particularly with respect to a number of aspects that relate to its utility as a power source for electric vehicles. Recent results from a large internationally coordinated research programme indicate that: (ⅰ) with proper attention to construction, valve-regulated lead/acid batteries can be deep-discharged many times without capacity loss; (ⅱ) lead/acid batteries can be recharged extremely rapidly so that long journeys of electric vehicles become a realistic possibility; (ⅲ) ranges of over 150 km between charges are achievable, and (ⅳ) the introduction of significant numbers of lead/acid-powered electric vehicles does offer a beneficial environmental impact.
