三星又陷“电池门” 不过这次大概不会炸了_我的网站

一 |     GLASTONBURY, Conn. -- A former Connecticut police officer is suspected of being a serial burglar and committing 30 or more thefts in three states, including the community he had patrolled until recently. A newly unsealed warrant says former Glastonbury Police Officer Patrick Hemingway is believed to have targeted safes and cash registers at restaurants and businesses in Connecticut, Rhode Island and Massachusetts. The warrant, cited in multiple news reports and released Thursday, says surveillance videos show a suspect possibly resembling the former officer.Hemingway, 37, was charged last month with computer crimes and making a false statement. A judge at his arraignment said more charges were expected. In one surveillance video, a tall male wearing a mask, gloves and a hooded sweatshirt is seen holding a flashlight “in a tactical manner.” The suspect is also holding “a coiled, corded object to his left ear” that resembles the portable police radios used by the Glastonbury Police Department, the warrant said.“Lock-picking tools” were used in some of the burglaries, according to the warrant. Hemingway left behind a bag that included a lock-picking tool kit when he resigned Sept. 1 from the Glastonbury Police Department, the warrant said. Cell phone data and images of a vehicle resembling one owned by Hemingway's wife and spotted at multiple break-ins are also cited in the warrant.As the burglary part of the investigation continues, Hemmingway is being held on a $1 million bond. His lawyer argued in court that the bond was too high. “I've seen murder cases where the bond is that high,” James E. Sulick said. “I want to withhold any comment until I’ve had a chance to review things with my client,” Sulick said Saturday. “And I just haven’t been able to do that yet.”Hemingway was initially arrested as a fugitive from justice on Sept. 22 at a New Jersey airport where Sulick said he was studying to become a commercial pilot. He was extradited to Connecticut. The warrant for the computer crime, signed when Hemingway was in New Jersey, stems from allegations he misused a police database 80 times. According to the warrant, Sulick made 28 queries about his own vehicle from Feb. 26, 2019, as well as 19 queries about his wife's vehicle from April 11, 2022 to Aug. 23, plus other queries."A possible explanation for Patrick running such information so frequently would have been to determine if he was being investigated by police,” the warrant said. Last month, the Glastonbury Police Department issued a news release saying they had been alerted to the possibility that a former officer was a person of interest in a recent burglary and had contacted the Connecticut State Police Major Crimes unit because the investigation involved multiple jurisdictions. The officer was not named and the department said it would not comment further.。    
在与其他人交流后，他发现其他数码 UP 主也注意到了类似的情况。

二 | 出现问题的手机覆盖范围很广，从古早的三星 Galaxy S4 ，一直到相当近的 Galaxy S20 FE 甚至是Z Fold 2 ，都有出现问题。他说，自己在公开曝光这件事之前，已经等了 50 天，然而三星一直没有给出回复。
一直到视频发出半个月后，三星终于给出了啥也没给的回复：得知这件事的托尼立刻进行了一次身边统计学，结果出人意料，又在情理之中：情理之中的是，整个编辑部能找到的三星手机加起来少于 5 部。你说这图和三星无关？无关就对了……▼
而意料之外的是，在抽屉里长期储存的那些三星手机，都没有出现那位 UP 主描述中的鼓包现象。不过上微博转了一圈，托尼发现在事件发酵前， 就已经有不少中国用户反映三星的电池容易鼓包了：


由于这次“ 电池门 ”涉及到的型号和生产时间跨度太大，托尼认为这事不太像是品控或电池厂商问题，更有可能是三星的某种系统性失误。而这个失误， 最先让人想到的就是三星的电池选型。在 Note7 成为哑火手雷之后，三星痛定思痛，决定改用不太可能起火的凝胶电池。在此之前，市场上只有索尼采用这种电池。

三 | 大多数手机电池用的是 液态电解质的 锂离子电池，也就是说，电池内部有很多流动性不错的有机液体。

四 | 这种有机溶液一旦碰到高温（ 比如电池短路 ）或水蒸气就会分解，产生大量气体。

五 | 一旦电池包装被气体吹爆或是被外部刺穿，电解液就会流出电池，与空气大面积接触，造成起火。而凝胶电池的电解质类似于果冻，即使包装破裂，也不会有电解液流出，大大降低了起火几率。

六 | 与一般锂离子电池相比，凝胶电池更安全，而且充放电时对电极的损耗更小，容量衰减慢。

七 | 但凝胶电池生产工艺复杂，价格高；能量密度低，而且电池内阻大。这就导致凝胶电池既贵，容量又小，充电还慢，属于是完美地反向切中手机的续航痛点。因此，没有产品大“ 爆 ”过的手机厂商，一般不会选择凝胶电池。三星延续至今的 25W “ 快 ”充估计就有电池的因素 ▼
当然，凝胶电池作为一种三星特色，最容易让人怀疑与这次三星独占的“ 电池门 ”有关，但也不是三星电池鼓包的唯一可能原因。

八 | 毕竟这次爆出的鼓包手机并不全都使用了凝胶电池，比如较早发布的三星 Galaxy S4 和 S7 就是一般的锂离子电池。
因此托尼同样怀疑，三星在电池管理方面有缺陷。这可能导致三星手机在长期关机的情况下，电池快速进入过放状态。现代手机关机后，主板上的某些元件可能仍然在工作。

九 | 比如大多数手机都支持的关机闹钟和定时关机，就需要记录时间的芯片不断电。
但如果三星的电池管理方案，不会在电池电量低的情况下完全切断主板电源，就会造成过度放电。过放会对电池造成相当严重的损伤。其中一个表现就是电解质在电极上分解，产生大量气体，进而导致鼓包。
当然，相比过度充电或电池内部短路造成的损伤，过放不太可能造成燃烧和爆炸，因为过放状态的电池，能量已经基本耗尽了。但无论是什么原因，鼓包的电池都不该重新充电，它的内部结构可能已经损坏，充电时说不定就会给你来一下狠的。这次三星电池门，从 Mrwhosetheboss 首次报告到现在已经过去两个半个月了，但三星依然没有给出一个有用的答复。虽说电池鼓包并不罕见，但让一群数码大 V 不得不公开质疑产品来为自己要个结果，三星这次无论是产品还是公关，都有不小的问题。还好这次电池不会突然烧起来，不然三星又要挨上一棒了。
