bater\u00eda 21700<\/a> alberga m\u00e1s de 40% de capacidad en comparaci\u00f3n con las celdas 18650. Todo ese extra de energ\u00eda significa que las bater\u00edas 21700 pueden te\u00f3ricamente alimentar tus dispositivos considerablemente m\u00e1s tiempo antes de necesitar una recarga.<\/p>\nTasa de descarga<\/h3>\n
Gracias nuevamente a m\u00e1s espacio interno, las celdas 21700 soportan tasas de descarga de hasta 75A, superando con facilidad a la mayor\u00eda de las bater\u00edas 18650 que alcanzan un m\u00e1ximo de menos de 35A de descarga continua.<\/p>\n
Una mayor capacidad de descarga se traduce en dispositivos capaces de un mayor consumo de energ\u00eda. Por ejemplo, la misma herramienta el\u00e9ctrica equipada con una bater\u00eda 21700 funcionar\u00eda m\u00e1s r\u00e1pido, con m\u00e1s fuerza y durante m\u00e1s tiempo en comparaci\u00f3n con el uso de celdas 18650 de menor potencia.<\/p>\n
Densidad de Energ\u00eda<\/h3>\n
La densidad de energ\u00eda mide cu\u00e1nta energ\u00eda puede almacenar una bater\u00eda por unidad de volumen. Y gracias a su tama\u00f1o optimizado, la mayor\u00eda de las celdas 21700 alcanzan una densidad de energ\u00eda alrededor de 20% mayor en comparaci\u00f3n con las bater\u00edas 18650.<\/p>\n
M\u00e1s energ\u00eda empaquetada en el mismo espacio significa tiempos de funcionamiento m\u00e1s largos en los paquetes de bater\u00edas 21700 sin aumentar el tama\u00f1o o peso.<\/p>\n
Disponibilidad<\/h3>\n
Dada su popularidad en port\u00e1tiles, herramientas el\u00e9ctricas y otros dispositivos, las bater\u00edas 18650 actualmente disfrutan de una disponibilidad m\u00e1s amplia entre las principales marcas de bater\u00edas. Desde Samsung hasta Sony, todos producen sus propias celdas 18650.<\/p>\n
El mercado de bater\u00edas 21700 es, admitidamente, m\u00e1s peque\u00f1o pero est\u00e1 creciendo. A\u00fan as\u00ed, los principales fabricantes de bater\u00edas est\u00e1n aumentando r\u00e1pidamente la producci\u00f3n de celdas 21700 para satisfacer la demanda creciente.<\/p>\n
Costo<\/h3>\n
Por volumen de producci\u00f3n, las celdas 18650 tienden a ser la opci\u00f3n m\u00e1s econ\u00f3mica, al menos por ahora. Sin embargo, su menor capacidad significa que se necesitan m\u00e1s celdas 18650 para lograr los mismos voltajes en los paquetes de bater\u00edas que las opciones 21700.<\/p>\n
Y a medida que la producci\u00f3n de 21700 aumente hasta el nivel de las 18650, las econom\u00edas de escala deber\u00edan traducirse en celdas 21700 con mejor coste por mAh en un futuro cercano.<\/p>\n
\u00bfSon mejores las bater\u00edas 21700 que las 18650 en general?<\/h2>\n
Aunque la comparaci\u00f3n entre 21700 y 18650 tiene matices, 21700<\/strong> suelen ganar en la mayor\u00eda de las m\u00e9tricas de rendimiento directo.<\/p>\nEl formato cil\u00edndrico de tama\u00f1o \u00f3ptimo de 21700 desbloquea una capacidad y una capacidad de corriente considerablemente mayores en comparaci\u00f3n con las alternativas 18650. Y su precio, que desciende lentamente, junto con su creciente disponibilidad, auguran que las celdas 21700 se conviertan en una opci\u00f3n preferida en muchas industrias.<\/p>\n
Sin embargo, las bater\u00edas 18650, con m\u00e1s tiempo de prueba, siguen funcionando excelentemente para dispositivos de bajo consumo. Su tama\u00f1o m\u00e1s peque\u00f1o tambi\u00e9n hace que las celdas 18650 sean ideales cuando el tama\u00f1o reducido sigue siendo cr\u00edtico, como en dispositivos port\u00e1tiles compactos.<\/p>\n
Pero para la mayor\u00eda de los usos de alta demanda \u2014 ya sean veh\u00edculos el\u00e9ctricos, herramientas el\u00e9ctricas o bancos de bater\u00edas \u2014 las bater\u00edas 21700 son mejores. Su abundancia de capacidad significa ofrecer tiempos de funcionamiento mucho m\u00e1s largos y un rendimiento superior que las bater\u00edas 18650 podr\u00edan lograr de manera fiable.<\/p>\n
Por lo tanto, si se presenta la opci\u00f3n, elegir 21700 en lugar de celdas 18650 suele tener mucho sentido si tu dispositivo puede aprovechar las capacidades de 21700\u2026 siendo los tiempos de funcionamiento prolongados y la operaci\u00f3n de alta potencia solo el comienzo de las ventajas que ofrecen estas celdas cil\u00edndricas de mayor tama\u00f1o.<\/p>\n
Puntos clave: Diferencias entre bater\u00edas 18650 y 21700<\/h2>\n\n- Las bater\u00edas 21700 tienen un tama\u00f1o f\u00edsico mayor de 21mm x 70mm en comparaci\u00f3n con las 18650 que miden 18mm x 65mm<\/li>\n
- Las celdas 21700 ofrecen en promedio 40%+ m\u00e1s capacidad (3000-5000 mAh) frente a las 18650 (2000-3500 mAh)<\/li>\n
- Las bater\u00edas 21700 alcanzan tasas de descarga continua m\u00e1s altas, t\u00edpicamente m\u00e1s de 75 amperios frente a menos de 35 amperios para las 18650<\/li>\n
- Las celdas 21700 ostentan una mayor densidad de energ\u00eda, aproximadamente 20% m\u00e1s, gracias a un volumen interno aumentado<\/li>\n
- Las bater\u00edas 18650 actualmente se benefician de mayores vol\u00famenes de producci\u00f3n y disponibilidad<\/li>\n
- El precio por mAh deber\u00eda favorecer a las bater\u00edas 21700 a medida que la producci\u00f3n aumenta para satisfacer la demanda<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
