AG5 battery!Analyze the differences in R&D and design of power lithium-ion batteries and ordinary lithium-ion batteries

Differences in the research and development design of power lithium batteries and ordinary lithium batteries: 1. The research and development design of lithium iron phosphate power lithium-ion batteries need to consider reliability and consistency more. After all, it takes a long time (at least 5 ~ 10 year), environment (low temperature in winter, summer sun, rain and snow), large amounts of electricity

Differences in R&D and design between power lithium-ion batteries and ordinary lithium-ion batteries:

1. The research, development and design of lithium iron phosphate power lithium-ion batteries must consider reliability and consistency. After all, it takes a long time (at least 5 to 10 years), the environment (low temperature in winter, the sun in summer, Rain and snow), a large number of batteries are used in series and parallel groups, considering reliability and consistency, it is considered that the car uses 1000 power lithium batteries. Under ideal circumstances, the manufacturer hopes that 100000 car models are not required according to the scale of the problem. Problems with power batteries (safety, storage, circulation, etc.) are more likely to be less than one part per 100 million (of course, regarding the most high-end consumer batteries, Apple also requires this level from its suppliers. Considering reliability, power lithium batteries are usually Designed to be more redundant, with thicker membranes, foils and casings, they have about half the energy density of regular batteries.

2. Ordinary consumers should consider safety and durability when developing and designing lithium-ion batteries, not long-term reliability (don't cycle it, because it will last one or two years), and usually don't use matching sets alone. , so there is not much consistency requirement, but because the pad space of consumers’ mobile phones and tablets is limited and very precious, consumers have strict requirements on the size, capacity and energy density of lithium-ion batteries.

3. The difference between lithium-powered lithium batteries and lithium-ion batteries Regarding product safety, more external power lithium battery protection circuits, heat dissipation layout, etc., of course, also face harsh conditions (external high voltage, large current, more complex (external environment), consumers reduce battery protection and must resist safety risks based on a higher energy density battery material and design; high-end consumer mobile phone lithium-ion batteries use the most advanced technology and materials, while power Lithium batteries require more advanced process control, consistency control and quality management.
